If you find this milkshake in the oil cap, and not the coolant as well, then check the oil dipstick. If the oil on the dipstick is not mixed with water, the head gasket is fine and you need to take longer drives in cold weather to allow the PCV system to clear the condensation buildup.
That white "cream" is not a sing of a blown gasket ;) when you use the car for short rides then it's built up(in older cars) but when you go long distance then it must disappear. when it doesn't then have you a gasket problem. but the oil in the coolant is a clear sign :/

As many have pointed out, white sludge on the oil cap is not a definitive measure of head gasket health. In VW's, a leaking seal around the oil cap or the oil filler head could be to blame. You need to test your coolant system for exhaust gases to get a sure answer.
It's condensation caused by short trips. Engine gets warm and your bottom rocker is still cool, when the engine hasn't been on a long enough trip to burn off the oil, this sludge forms. You'll see on cars with bigger engines (that take longer to warm up) that they will have an oil catch can. Trick is to just clear some of that out then take it for a big run on higher RPM
A lot of the times, the oil cap will become milky like so if the vehicle is only driven lightly. The oil cap will become milky from condensation in the oil, and of course everyone knows water evaporates with heat, causing the water to rise to the highest point of the engine (the oil filler cap) there the oil mixes with the oil a lot easier since it is in a vaporized state. causing the milky cap. Judging by the coolant level, the condition of the coolant, colour of said coolant etc i would say this vehicle does not have a blown head gasket.
I have a vw bora with the 1.6SR(8V) engine that does the same thing. It doesn't mix coolant with oil at all. I've changed the oil multiple times and i've never had to fill more coolant. These vw engines just tend to gather more moisture inside the engine than other engine types. I've driven ~45 0000km with my car in a year with moisture forming in the oilcap, no problems at all. I drive long trips too and there is still some condensation in the engine so even though you drive the engine warm, it may still form some condensated water in the engine. TL;DR My vw does the same, no blown headgasket.
I'm glad I read these comments. My wife's Equinox has slight amount on her cap. We had a manifold replaced and the guy said we might have one cause of that. I been worried and looking at videos. There is nothing in the reservoir and nothing on the dip stick. And she only drives 10miles round trip to work and back. This really helped thank you.
really like your videos and respect you as a mechanic but this is not a sure symptom of a blown head gasket. can be caused by internal condensation or a dodgy PCV vale.
This can sometimes happen in a smaller amount in the winter when you get condensation under the oil cap. It will tend to not happen in the summer months..
I used to have a 2litre Octavia it had that mayonnaise on oil cap it's a known VW/Skoda issue , condensation getting into engine not head gasket, if head gaskets gone you will have that milky colour stuff on the oil dipstick,or oil will be in the coolant expansion tank.
Hi Good advice .but be carefully as older vw engines have the issue that if they are not run up to temp regually or do short trips they do collect condensation in the cam cover .which will give you that mayo stuff at the top of the oil filler .everyone's first thought is omg my head gasket has blown .but this is a commen thing on vw.s Regular oil changes and longer runs up to temp and it gets rid of the issue but like a lot of things its not always the obvious head gasket But as you say just to be safe watch you water levels and check water for oil also Love your vw bids keep em up mate
Utter bollocks! If the oil in the sump isn't emulsified (or Mayonnaise as you call it) but the filler cap is. Then thats caused by condensation because the engine is not run hot for long periods to boil the condensate off completely so it emulsifies the oil where it settles high up in the engine. You really shouldn't do these videos when you don't know what you're talking about fella. See if there's any goldfish in the diff while you're under there
Exactly lol he didn’t even say to look inside the valves and see if you see the milky cream most the times the cap is milky and the valves look beautiful
I'm by far an expert but as already ready stated in the previous comments this isn't a sure sign of the head gasket going it's just condensation building up due to short journeys and not allowing the car to reach temperature, if you pulled the dip stick out and it looked like that I'd be slightly more worried 😳
It's condensation iv just bought a car what only got ran maybe once a month by an old man who went literally a half a mile to the shops. Cleaned it out and it hasn't came back 👍
In the cold or just from driving short distance the condensation it has no we’re to escape so it goes up this guy is a little off that doesn’t mean it’s blown
Accumulation of sediment on the oil cap on these and 1.4 engines is caused by poorly solved moisture venting from the engine, and the return is connected to the part below the oil cap, so sediment accumulates on it and often leads to clogging, which can cause oil to break out on the oil quantity gauge and in in extreme cases, it also affects the condition of the engine,
Oh yeah. Very good suggestions. When gasket is gone oil become white and water become dark. Another suggestion I feel to add is this. Many idiot seller of used cars change the water and clean the oil cap to sell the car. If it's possible try to open the valve compartment cap. You can see the situation of the valves and gasket in a more accurate way. On many European cars this is made by removing only 2 10mm bolts.
VW's are notorious to having some milky stuff on the oil cap. Every VW i have worked on has had this stuff on it and it's never had a bad head gasket they just make allot of condensation. Probably a design flaw.
Sam Stocks Looking at this myself currently because a car I just got I think has a head gasket blown. You can buy a block testing kit from ebay which uses the vapours from your radiator / coolant bottle and passes through a chemical which changes colour to indicate a leak of exhaust gases into the coolant, if you take it to a garage they should be able to take a HC reading using an exhaust gas analyser from your coolant bottle to indicate the same. It's true that Mayo under the filler cap CAN indicate a gasket problem but it can also form from condensation built up due to only making short journeys, I've had air cooled cars that did this and there's no way coolant is mixing on one of those.
No. My 2.0L TSI engine doesn't have any milky oil on the oil cap. Never has. Though I do have a catch can which has milky oil. But all catch cans ever have milky oil.
Most oil caps have a slightly milky looking substance on the cap. It does look like a bad head gasket but sometimes it’s just condensation and oil inside the cap. Just because the cap has it doesn’t mean the oil is that way. Check the oil not the cap
I had this problem on a fiat the oil filler cap was like that but there was no water in the expansion tank changed the head gasket all was good again :) now I had the same problem with a mk 4 golf 1.6 petrol, oil filler cap full of shit like on the video but the coolant was full and no signs of oil contamination and no overheating this time it was condensation so not always a head gasket failure.
stuart robinson ive got gunk on my cap really bad my top breathers wer blocked theres none on the dipstick i changed the oil and done a engine flush i found a tiny blob in the oil filter and i can see a tiny leak i say tiny as ive had the gunk for about 2 months i park it in the same place evrey night and there is not one drop on the floor im not really loosing oil no over heating no loss of water just normal it looks like the leak is comming from i think its a fuel or oil sensor near the rocker cover at the top its above the air con motor i know this as thats coverd do you know if a rocker cover or sensor could cause this or no a way of finding the leak cheers?
I owned a Peugot 405 with a cracked head gasket at 187,000 miles. The symptoms were water vapour and burnt oil coming out of the exhaust (tailpipe). You'll know it's going because you have to keep topping up the oil level and oil puddles are left on the road beneath the car when parked. The spherical container you are checking is for anti-freeze into the radiator. Steam coming out of there is also a sign the head gasket has cracked.
@@Zoldier92 Because at 0:55 he says "...there could be water in your oil" while removing the coolant tank cap! Not once does he refer to coolant / anti-freeze while fiddling with that cap - misleading.
Failing or failed PCV can also cause some mayo, at the same time also burning white smoke from the excessive oil vapour passing through the intake, cylinders and exhaust, giving same symptoms as a failing/ failed head gasket, pourus/cracked head
My oil looked like a mayonnaise shake. Most of my coolant was in my oil. Owner of a garage for almost 40 years told me I had at least a blown head gasket if not a cracked or warped head and said I was delusional for believing that something else besides the head gasket could do that. Glad to say that it wasn't my head gasket. It was my first thought that the lower intake gasket may have been bad. I came up with that conclusion when I noticed above the number six cylinder the intake gasket had looked a little damp like oil or something was on it and while it was running I seen a few tiny bubbles around the same area. Every couple weeks I like the lift up the hood start the car and just stand there and listen to it while I'm looking the motor over.
@@Gra1947eme Don't know what you were going to say but the van is still running strong and doesn't burn oil even after that mess I had there. My Windstar has over 278,000 miles on it now. And I still every week or two let it run and just listen and look around.
get a block tester that will tell you if there are combustion gases in the cooling system or if u want to no if any of the cylinders are cracked perform a cylinder leak down test
For me it creates only before winter time, and when you drive short distances, long distances disappear. Amount of oil is not increasing or decreasing. And that appeared since the last oil change. It's a VW Golf Mk3 1.8 55kW. The mechanic told me he wants before the cold weather and the bad oil.
BMAC VAGS It also said the mechanic-condensation. Now the cold weather, and now appeared. One hour at 1000rpm all disappears. Provided that the thermostat is ok, 90 C. Short distances create the an emulsion.
Thats totally normal! If u drive the car for short distance it gets like this, totally normal. It's when the hot air in the breather mixes whit cold air that suck in. Drive the car hot for a long distance and it goes away
if a car has been stored for a long time with say 1/2 full gas tank you get condensation build up in the tank. running the car for a short while you will see steam and water vapor coming out of the tail pipe. it should go away , if it's still there after warm you have a blown gasket.
Vauxhall Astra 2002 8 valve engine does this all the time, not because the head is damaged, because the cooling system is shite and constantly over cools. This can be a sign of cyl head damage but its not conclusive
Look dealt with blown headgaskets before. To the point if your car is getting hot on the guage pull over immediately. If your head gadget is blown. Buy k seal it works and it is permanent if the engine is not completely shot. You need to be having severe problems to replace a headgasket due to the cost. K seal and other things create foam in the radiator. Some say foam is a sure sign of a blown headgasket no no it is not. You need to have severe severe issues for kseal or another good sealer not to work. People trying to put fear in people and tell blown gasket from the roof. Even if it is a headgasket my answer is so what. Very easy to fix with k seal done it before drove the car for a year and a half still runs. You need a couple confirming signs of a blown gasket. People spread fear so much that when my car had white smoke when it was cold I thought blown gasket. I seen a mailtruck blowing more white smoke then my car the same day. I was relieved and was able to start thinking logically without fear clouding my judgement.
Condensation (water) builds up inside your engine every single time you drive it. If you don't get it to running temp on a regular basis you don't get it hot enough for the condensation to evaporate and you will have milky build up on the cap like you see. Check to see if the oil on your dipstick is milky, if your antifreeze needs to be regularly topped up but you're not leaking and or if you have white smoke from the exhaust at running temp. Those are ways to tell if your head gasket is gone, sir.
Mine looks like that but there are no other signs of a blown head gasket, no smoke from exhaust, no loss of power or funny noises. I do have a coolant leak however, but it's coming from the water pump.
I had that oil cap sign in a VW Jetta, where there was coolant leaking from the external coolant hose flange to the outside, causing secondary overheating. The milk on the oil cap was grossly milky, more dramatic than you show here, though the oil at an oil change was normal. A leaking coolant hose flange is a fairly common problem with that (early 2000's) generation of gasoline Jetta. Although I was worried about a head gasket leak, the finding permanently resolved when I replaced the $20 coolant hose flange! I did a vid of that repair. As far as why it did that, I can only speculate, and I'm still puzzled. Perhaps trapped air in the cooling system caused enough of an overheat that steam formed inside the engine, mixing with oil as it later cooled. Or maybe steam in the engine compartment was somehow drawn back through the oil cap or intake to create that milky appearance. I suppose the driver may have left the oil cap off one day, but I didn't get a good history of that. The lesson for me was not to consider a milky oil cap as a completely reliable sign of head gasket problems. I would want to find combustion gasses in the coolant before committing to a head gasket diagnosis.
Headgasket failure can be pretty tough to diagnose properly, and this symptom alone is not 100% accurate. But I have also seen bubbles in the return hose in conjunction with irregular overheating. This milk has also been getting progressively worst, so that kinda eradicates the condensation theory. The diagnostic also registered a misfire on cylinder 1, once again maybe nothing, may be something, however I am just collecting the evidence before I come to a conclusion. Thanks for subscribing to the channel
I think a lot of these problems came from the owner buying one of those cheapy thermostats. when I had the car on the diagnostics it was reading 76c, but on the gauge in the cluster is was reading 90c. As you know these cars are ultra sensitive to temperature and voltage readings. For this reason I always preach that when it comes to the temperature sensor, always buy original.
On that same problem referred to above, I had a coolant temp sensor code, but just by replacing the coolant hose flange and burping properly, that code disappeared. In retrospect I think the coolant temp sensor was giving spurious readings (too low) because of trapped air. Trapped air has been a great source of humility for me.
Hello my golf 2.0 mk4 gti has the same on the oil cap my car uses no oil or water did 120 miles round trip it didn't miss a beat it's just condensation
my VR6 Jetta GLX with 316,000 miles had a head gasket go, cus I ran it with a broken belt serpentine, then belt and power steering pump that took out belt was fixed ran engine and you could hear the gurgling in the water tank, then I bought a new GTI.....even more fun..I may still be driving it, if I just stopped as soon as the belt let go, but I kept going another 7 miles with over heat alarm steam under the hood, didn't want to be staying on the highway...poor VR6, it never let me down ever, until it had the major issue...
you do a compression test and leak down test, and check the head for flat , oh yeah when your oil looks like that guys,.... your bearings are shot too and so are the crank jounals.
Wow !!!........you also might wanna check the front fork seals on that too could be blown! Or the bearings in the muffler are broke and clogged something?
I THING THAT MIGHT BE THE SENSOR BEARINGS, THEY JUST SEIZED UP, IF NOT IT CAN BE PROBLEMS IN THE EGR VALVE , TOO PRESSURE AND IT BLOW JOB IT,,, MILKIN THE WATER RESEVOIRE. OR MAYBE ITS JUST FUKIN NORMAL , ABNORMAL.
ammmmmm this can ALSO happen to any car that does short journeys because the oil is not heating up enough to boil off and dispurse moisture in the oil from the atmosphere, and the car is not getting regular enough oil changes. wipe the cap and take it for a really long drive it will clear up. if the head gasket is gone the car may over heat and when running the expansion bottle will bubbling it will be a sign of pressure leak. with that much so called water in the oil the water bottle should have a layer of oil on it that you could mistake for skin. also on some cars ie vws you may find when car reaches running temp the heaters go cold. so just saying unless the car is over heating i would not take that as a sure sign the head gasket is gone
+Phil Murphy I'm currently having this problem and is making me have nightmares....I only use my car to drive to work and it's only 2 miles away from home. also the weather just changed from cold to hot(I've read that could be it too) but my car is not overheating when I drive it. Ive had the car for almost 3 years and this never happened and ive always had the same routine. What should I do?
Drain all water cut a broom handle put it in the pipe that feeds the expansion bottle put a pipe clip round it so on water can get in to the engine refill expansion bottle change oil take it to auction will run sweet for about 5 minutes 👍👍👍
When I bought my mkiv GTI the oil cap had all kinds of gunk like that but it was because the car had been sitting at auction for months turned out to be just moisture in the oil still driving to this day with no problems 200k miles and not a single problem not even a check engine light lol🤪
Hi and many thanx for your informative videos! Maybe u can help me out a little. My golf IV 1,4 AHW keeps losing huge amounts of engine oil. The red oil can sign illuminates also ofcourse. We´re talkin about 1,5 litres per 400kms. The oil doesn´t leak out from anywhere, theres no pool of oil under the car. Is it a stuffed egr / pcv valve hoses that forces the oil to the cylnders or what? Cheers, .Nicolas
That’s not entirely accurate, sometimes if the car has been sitting a while especially if there is a lot of humidity the oil cap will look like this. The only way is to actually check the oil and coolant for mixing. Or if you want to get real technical, do a compression or leak down test.
I had water leak through steam.for 4 years.Then it started to overheat when pushed.one year later I decided to change the head gasket, drive wheel (because I had to) and clutch After that I started to get maionese on the oil and the car didn't pushed has it used to. The mechanic said that maybe the turbo was dirty and the oil difuser gone. I said "Fuck off" . Bought a new car. Probably he fitted used parts on the drive wheel/clutch kit and god knows what he did with the head gasket. I miss putting water on my golf...I loved the car. Hope the mechanic gets sued and goes bankrupt.
Hello just watched your video I have a mk4 2.0 it's a w reg I have milky on my oil cap my car uses no oil or water engine is breathing heavy when the cap is of runs very well I have cleaned some of the hoses out what could be wrong
That could be caused by moisture upon cold start ups. The moisture caused by combustion ends up as blow by and ends up on your oil cap. Now if you have oil in your coolant, that is a sign of a head gasket leak. Moisture can also accumulate in your oil because of blow by and create the known milkshake substance people fear as a blown head gasket.
Wrong. It is oil that leaks into the coolant passages when head is blown 'cause oil pressure is greater. The first thing to check is the quality of coolant.
Hi pal, my golf mk4 2.0 has this under oil cap, but not as much water just foamy mayo, and the oil at dipstick is fine with no mayo! Coolant bottle also fine, how long will the car last if continued to be driven as is? And would a gasket sealant solve the problem? If so which do you recommend? Any help/advice is appreciated my man! Thanks for your time :)
It could just be condensation, you will need a little more evidence before 100% confirming that is the problem. Is your car giving you andy mechanical problems for you to worry about?
Not that I know of? I have just dropped the oil and changed filter, changed coolant to g12, the foam takes a few days to come back once I clean it off? It has a strange smell sometimes when I smell in the filler, its only used twice a week or so for short journeys at the min but im wanting to start up a business and sign write the golf? Any ideas! Also do you recommend a gasket sealant that's safe if it is this? Many thanks
I don't really believe in gasket sealants so I personally would not advise it. The short journeys could be causing your problems, you may have more of a condensation issue rather that a head gasket. If you develop further problems, then I would suggest that you look into it otherwise just keep a eye on it.
Sorry for all the questions, but what problems shud I look out for? And if my car stays the same will it be okay to carry on driving as it is ( its a v reg ) with 104,000 on clock? Any main things I should look out for? Im fairly new to motors ive learned off your vids for my services, brakes etc... Thanks again for your time/advice :)
Steve West hi there i have the same problem with my octavia (i think the engines are the same) and i think may be is the head gasket gone. But i drive the this car almost 4 years(about 10,000miles) like that and still drives fine :)
I have had the head gasket go on 3 of my cars so far. One of the other signs that I found was that there was loads of pressure when opening up the radiator cap. Thankfully the gasket has not gone on my VW but will pressure build up there on these too?
that's not completely true. it can just be condensation that got in the gas cap I have a car lot and that happens a lot need to pull the dipstick out check oil that way if you see milky oil then there's definitely a problem
I have this on a 1.6 golf runs sweet but has a milky cap and quite a bit of water coming out of exhaust. it's been stood for 2 months so could it just be condensation from that.also quite a bit of vapour/mist out of exhaust
Replace head gasket if only your car engine was overheating. Overheating also may cause by other parts. Please check on cooling system,sensor, radiator,fan,hose,waterpump,thermostat and leakage which will cost cheaper and easier to do before jump to conclusion of blown head gasket and replacing it. Unless your car is 7yrs old and above, you may do top overhaul which cover most of the problem and bring back your car perfomance as new. Top overhaul probably around $800-1k, change head gasket+skim head $500-700. If your car does not overheat, rather kept that money and do one time top overhaul. DIY should be below $200 replace without skim head(high risk + problem may occur again),send to machinist for skim add another $200-300 (depend on machinist price) , this is average rate or may i say common price for this kind of repair.
I find unless you clean it off every month or 2 mostly in the winter months, There will always be some milkyness up there on the cap. It is normal on those engines. sometimes the seal on the oil cap isn't perfect seal and you always get some condensation build up around the cap and the lip of the oil filler especially if the car does short journeys. That stuff also gets sucked into and melts away the rubber pipe which feeds a valve back to the air intake too it's worth taking that apart and cleaning it on oil changes if needed. However if you see that stuff much below the cap around the entire oil filler neck or on the rockers like on that example on the video. If it's around the dipstick too. There's clearly an issue.
I have this milky stuff! I drive about 2miles every evening in the winter and 2miles back at night uk wether no oil in reservoir and it’s not losing any coolant is this condensation or head gasket
I have oil i believe a light slush in my resivour, i noticed it last night but my car has never been out of water or oil and runs the same , really dont know whats going on question is do i drain my resivour and see if it returns? Dont mustard on my oil cap
VW watercooled lumps all get this. condensation, not blown HG. Usually caused by short runs. my wife's Golf 1,8T has worse than this for the last 5 years.....
If you find this milkshake in the oil cap, and not the coolant as well, then check the oil dipstick. If the oil on the dipstick is not mixed with water, the head gasket is fine and you need to take longer drives in cold weather to allow the PCV system to clear the condensation buildup.

Are you a mechanic or just gloves user:) this sign of a short trip driven car, not a sign of any blown gasket.
DO YOU WANN TELL ME THE LOTTERY NUMBERS?, I WOULD THNAK YOU A LOT.
the mayo appears for me only in the winter, and its the same stuff that appears in differentials aswell, its just condensation :D
In the cold or just from driving short distance the condensation it has no we’re to escape so it goes up this guy is a little off that doesn’t mean it’s blown
Sure sign of living in Seattle, probably may parts of UK, as well.
Accumulation of sediment on the oil cap on these and 1.4 engines is caused by poorly solved moisture venting from the engine, and the return is connected to the part below the oil cap, so sediment accumulates on it and often leads to clogging, which can cause oil to break out on the oil quantity gauge and in in extreme cases, it also affects the condition of the engine,
Oh yeah. Very good suggestions. When gasket is gone oil become white and water become dark. Another suggestion I feel to add is this. Many idiot seller of used cars change the water and clean the oil cap to sell the car. If it's possible try to open the valve compartment cap. You can see the situation of the valves and gasket in a more accurate way. On many European cars this is made by removing only 2 10mm bolts.
Could also be the oil cooler that has colapsed internally.
Not just straight to a head gssket.
VW's are notorious to having some milky stuff on the oil cap. Every VW i have worked on has had this stuff on it and it's never had a bad head gasket they just make allot of condensation. Probably a design flaw.
matthebest018 I've heard about that, my dad told me about it when he owned a mk 2, is there another way to check if the head gasket has gone?
Sam Stocks Looking at this myself currently because a car I just got I think has a head gasket blown.
You can buy a block testing kit from ebay which uses the vapours from your radiator / coolant bottle and passes through a chemical which changes colour to indicate a leak of exhaust gases into the coolant, if you take it to a garage they should be able to take a HC reading using an exhaust gas analyser from your coolant bottle to indicate the same.
It's true that Mayo under the filler cap CAN indicate a gasket problem but it can also form from condensation built up due to only making short journeys, I've had air cooled cars that did this and there's no way coolant is mixing on one of those.
IN A SECOND I CAN TELL YOU FOR SURE IF YOUR GASKET IS BLONW, DONT NEED TO ANALIZE THE SPERM WAHEL.
No. My 2.0L TSI engine doesn't have any milky oil on the oil cap. Never has. Though I do have a catch can which has milky oil. But all catch cans ever have milky oil.
Hi its 15th April 2020...Yesterday I saw that there is a sludge in the coolant, I have read most of your comments, but I will get a 2nd opinion, tks
Most oil caps have a slightly milky looking substance on the cap. It does look like a bad head gasket but sometimes it’s just condensation and oil inside the cap. Just because the cap has it doesn’t mean the oil is that way. Check the oil not the cap
this is not a sign of blown head gasket its only condensation. If your head gasket is blown you se gray oil on the dipstick.
I agree with you, but that's got to be blown head gasket?
I had this problem on a fiat the oil filler cap was like that but there was no water in the expansion tank changed the head gasket all was good again :) now I had the same problem with a mk 4 golf 1.6 petrol, oil filler cap full of shit like on the video but the coolant was full and no signs of oil contamination and no overheating this time it was condensation so not always a head gasket failure.
stuart robinson ive got gunk on my cap really bad my top breathers wer blocked theres none on the dipstick i changed the oil and done a engine flush i found a tiny blob in the oil filter and i can see a tiny leak i say tiny as ive had the gunk for about 2 months i park it in the same place evrey night and there is not one drop on the floor im not really loosing oil no over heating no loss of water just normal it looks like the leak is comming from i think its a fuel or oil sensor near the rocker cover at the top its above the air con motor i know this as thats coverd do you know if a rocker cover or sensor could cause this or no a way of finding the leak cheers?
Old cars are simpel and cheap to fix :-)
can you explain. Why grey?
That’s condensation caused by short trips, the only thing if the head gasket is gone is if the exhaust is blowing white smoke
Condensation possibly, quite common. I would look for other signs before diagnosing this as head gasket personally.
good channel though!
THE POSSIBILITY IS ALWAYS THE LOOSERS ANSWER. HOWEVER, THERE IS A POSSIBILITY YOU LOOSE A BET, DO YOU WANNA BET WITH ME?
GET A FUKING METALING DETECTOR AND FIND THE TREASURE|! THE POSSIBILITY IS HIGHT,.
Check if creamy stuff inside oil filler cap on a parts, not only on a cap or neck. Look deeper. It might be condensation.
mine does not have those signs but keeps on overheating on high way drive
I owned a Peugot 405 with a cracked head gasket at 187,000 miles. The symptoms were water vapour and burnt oil coming out of the exhaust (tailpipe). You'll know it's going because you have to keep topping up the oil level and oil puddles are left on the road beneath the car when parked. The spherical container you are checking is for anti-freeze into the radiator. Steam coming out of there is also a sign the head gasket has cracked.
yes
"the spherical container is for anti-freeze" . Why are you telling him like he doesn't know this?
@@Zoldier92 Because at 0:55 he says "...there could be water in your oil" while removing the coolant tank cap! Not once does he refer to coolant / anti-freeze while fiddling with that cap - misleading.
Failing or failed PCV can also cause some mayo, at the same time also burning white smoke from the excessive oil vapour passing through the intake, cylinders and exhaust, giving same symptoms as a failing/ failed head gasket, pourus/cracked head
Very true
My oil looked like a mayonnaise shake. Most of my coolant was in my oil. Owner of a garage for almost 40 years told me I had at least a blown head gasket if not a cracked or warped head and said I was delusional for believing that something else besides the head gasket could do that. Glad to say that it wasn't my head gasket. It was my first thought that the lower intake gasket may have been bad. I came up with that conclusion when I noticed above the number six cylinder the intake gasket had looked a little damp like oil or something was on it and while it was running I seen a few tiny bubbles around the same area. Every couple weeks I like the lift up the hood start the car and just stand there and listen to it while I'm looking the motor over.
Shawn Young I
@@Gra1947eme Don't know what you were going to say but the van is still running strong and doesn't burn oil even after that mess I had there. My Windstar has over 278,000 miles on it now. And I still every week or two let it run and just listen and look around.
Check the dipstick, not the oil cap. If the dipstick looks like chocolate milk, then it's a blown gasket.
get a block tester that will tell you if there are combustion gases in the cooling system or if u want to no if any of the cylinders are cracked perform a cylinder leak down test
For me it creates only before winter time, and when you drive short distances, long distances disappear. Amount of oil is not increasing or decreasing. And that appeared since the last oil change. It's a VW Golf Mk3 1.8 55kW. The mechanic told me he wants before the cold weather and the bad oil.
Do you live in a cold environment? Condensation can look the same sometimes.
BMAC VAGS It also said the mechanic-condensation. Now the cold weather, and now appeared. One hour at 1000rpm all disappears. Provided that the thermostat is ok, 90 C. Short distances create the an emulsion.
Nemanja Sreckovic It sounds like more of a condensation issue. Do you have any other symptoms?
BMAC VAGS No
Then I would not worry at all
Thats totally normal!
If u drive the car for short distance it gets like this, totally normal. It's when the hot air in the breather mixes whit cold air that suck in.
Drive the car hot for a long distance and it goes away
if a car has been stored for a long time with say 1/2 full gas tank you get condensation build up in the tank. running the car for a short while you will see steam and water vapor coming out of the tail pipe. it should go away , if it's still there after warm you have a blown gasket.
Thank you very much ,quick to the point👍
Good thing there's a lot of real mechanic here . That's just condesation build up and mixing with oil trap on the top baffle.
You have some really great videos that are really helpful. Delete this one.
Thank you
Vauxhall Astra 2002 8 valve engine does this all the time, not because the head is damaged, because the cooling system is shite and constantly over cools.
This can be a sign of cyl head damage but its not conclusive
Look dealt with blown headgaskets before. To the point if your car is getting hot on the guage pull over immediately. If your head gadget is blown. Buy k seal it works and it is permanent if the engine is not completely shot. You need to be having severe problems to replace a headgasket due to the cost. K seal and other things create foam in the radiator. Some say foam is a sure sign of a blown headgasket no no it is not. You need to have severe severe issues for kseal or another good sealer not to work. People trying to put fear in people and tell blown gasket from the roof. Even if it is a headgasket my answer is so what. Very easy to fix with k seal done it before drove the car for a year and a half still runs. You need a couple confirming signs of a blown gasket. People spread fear so much that when my car had white smoke when it was cold I thought blown gasket. I seen a mailtruck blowing more white smoke then my car the same day. I was relieved and was able to start thinking logically without fear clouding my judgement.
Condensation (water) builds up inside your engine every single time you drive it. If you don't get it to running temp on a regular basis you don't get it hot enough for the condensation to evaporate and you will have milky build up on the cap like you see. Check to see if the oil on your dipstick is milky, if your antifreeze needs to be regularly topped up but you're not leaking and or if you have white smoke from the exhaust at running temp. Those are ways to tell if your head gasket is gone, sir.
Did you just look in the coolant and call it the oil?
Mine looks like that but there are no other signs of a blown head gasket, no smoke from exhaust, no loss of power or funny noises. I do have a coolant leak however, but it's coming from the water pump.
I had that oil cap sign in a VW Jetta, where there was coolant leaking from the external coolant hose flange to the outside, causing secondary overheating. The milk on the oil cap was grossly milky, more dramatic than you show here, though the oil at an oil change was normal.
A leaking coolant hose flange is a fairly common problem with that (early 2000's) generation of gasoline Jetta. Although I was worried about a head gasket leak, the finding permanently resolved when I replaced the $20 coolant hose flange! I did a vid of that repair.
As far as why it did that, I can only speculate, and I'm still puzzled. Perhaps trapped air in the cooling system caused enough of an overheat that steam formed inside the engine, mixing with oil as it later cooled. Or maybe steam in the engine compartment was somehow drawn back through the oil cap or intake to create that milky appearance. I suppose the driver may have left the oil cap off one day, but I didn't get a good history of that. The lesson for me was not to consider a milky oil cap as a completely reliable sign of head gasket problems. I would want to find combustion gasses in the coolant before committing to a head gasket diagnosis.
Headgasket failure can be pretty tough to diagnose properly, and this symptom alone is not 100% accurate. But I have also seen bubbles in the return hose in conjunction with irregular overheating. This milk has also been getting progressively worst, so that kinda eradicates the condensation theory. The diagnostic also registered a misfire on cylinder 1, once again maybe nothing, may be something, however I am just collecting the evidence before I come to a conclusion.
Thanks for subscribing to the channel
Sure, I'm looking forward to watching your repair. I would burp the cooling system and then use one of those testers to look for CO2 in the coolant.
I think a lot of these problems came from the owner buying one of those cheapy thermostats. when I had the car on the diagnostics it was reading 76c, but on the gauge in the cluster is was reading 90c. As you know these cars are ultra sensitive to temperature and voltage readings. For this reason I always preach that when it comes to the temperature sensor, always buy original.
On that same problem referred to above, I had a coolant temp sensor code, but just by replacing the coolant hose flange and burping properly, that code disappeared. In retrospect I think the coolant temp sensor was giving spurious readings (too low) because of trapped air. Trapped air has been a great source of humility for me.
spelunkerd I will keep that in mind when diagnosing the fault
check coolant or oil for cross contamination of either.
I find the first sign is it's got that VW symbol on the front. And it's NOT just a head gasket. The WHOLE CAR is a heap....
I had a air cooled vw bug back in the day that did this all the time.
Hello my golf 2.0 mk4 gti has the same on the oil cap my car uses no oil or water did 120 miles round trip it didn't miss a beat it's just condensation
yep.
my VR6 Jetta GLX with 316,000 miles had a head gasket go, cus I ran it with a broken belt serpentine, then belt and power steering pump that took out belt was fixed ran engine and you could hear the gurgling in the water tank, then I bought a new GTI.....even more fun..I may still be driving it, if I just stopped as soon as the belt let go, but I kept going another 7 miles with over heat alarm steam under the hood, didn't want to be staying on the highway...poor VR6, it never let me down ever, until it had the major issue...
you do a compression test and leak down test, and check the head for flat , oh yeah when your oil looks like that guys,.... your bearings are shot too and so are the crank jounals.
Wow !!!........you also might wanna check the front fork seals on that too could be blown! Or the bearings in the muffler are broke and clogged something?
I THING THAT MIGHT BE THE SENSOR BEARINGS, THEY JUST SEIZED UP, IF NOT IT CAN BE PROBLEMS IN THE EGR VALVE , TOO PRESSURE AND IT BLOW JOB IT,,, MILKIN THE WATER RESEVOIRE. OR MAYBE ITS JUST FUKIN NORMAL , ABNORMAL.
mine has exactly that, zero compression on 4. im changing the head anyways LOL
ammmmmm this can ALSO happen to any car that does short journeys because the oil is not heating up enough to boil off and dispurse moisture in the oil from the atmosphere, and the car is not getting regular enough oil changes. wipe the cap and take it for a really long drive it will clear up. if the head gasket is gone the car may over heat and when running the expansion bottle will bubbling it will be a sign of pressure leak. with that much so called water in the oil the water bottle should have a layer of oil on it that you could mistake for skin. also on some cars ie vws you may find when car reaches running temp the heaters go cold. so just saying unless the car is over heating i would not take that as a sure sign the head gasket is gone
+Phil Murphy I'm currently having this problem and is making me have nightmares....I only use my car to drive to work and it's only 2 miles away from home. also the weather just changed from cold to hot(I've read that could be it too) but my car is not overheating when I drive it. Ive had the car for almost 3 years and this never happened and ive always had the same routine. What should I do?
*looks in coolant expansion tank* there could be water in your oil *expansion tank full of water* got me
Drain all water cut a broom handle put it in the pipe that feeds the expansion bottle put a pipe clip round it so on water can get in to the engine refill expansion bottle change oil take it to auction will run sweet for about 5 minutes 👍👍👍
Hey bud another great video , any chances you could make one on replacing rear axel bushes on mk4 golf thanks
When I bought my mkiv GTI the oil cap had all kinds of gunk like that but it was because the car had been sitting at auction for months turned out to be just moisture in the oil still driving to this day with no problems 200k miles and not a single problem not even a check engine light lol🤪
the symptoms for me were: swelling of the radiator outlet hose, elevation of temperature and water evaporation cooling , power loss in the mounted
Yes, these are also symptoms of a head gasket issue. It all depends how the head gasket breaks to what symptoms you are likely to see.
Hi and many thanx for your informative videos! Maybe u can help me out a little. My golf IV 1,4 AHW keeps losing huge amounts of engine oil. The red oil can sign illuminates also ofcourse. We´re talkin about 1,5 litres per 400kms. The oil doesn´t leak out from anywhere, theres no pool of oil under the car. Is it a stuffed egr / pcv valve hoses that forces the oil to the cylnders or what? Cheers, .Nicolas
The mayo never lies defo blown has happened too me a few times
U know what’s worse than a blown head gasket, an upside down oil cap! FLIP IT!!!!
Dacias come with Mayo always around the cap from factory with like 5-10 miles on it
Hahahaha
What's the next best thing to do buy a new car or a gasket
that looks live a 1.6 8v akl engine can please make a video that you change that headgasket because i have the same problem
My golf gti mk5 was worse than that oil cap. Apparently it's normal for short journeys and in winter.
That’s not entirely accurate, sometimes if the car has been sitting a while especially if there is a lot of humidity the oil cap will look like this. The only way is to actually check the oil and coolant for mixing. Or if you want to get real technical, do a compression or leak down test.
They call it underpants lol
Sure is a SMART WAY for sure !!!
Smart???... DUDE
where?»iMA NOT SEEING ANY SAMRT AROUND
So shitTY CARS.
Is it bad to keep driving with a blown head gasket ?
I had water leak through steam.for 4 years.Then it started to overheat when pushed.one year later I decided to change the head gasket, drive wheel (because I had to) and clutch
After that I started to get maionese on the oil and the car didn't pushed has it used to. The mechanic said that maybe the turbo was dirty and the oil difuser gone. I said "Fuck off" . Bought a new car. Probably he fitted used parts on the drive wheel/clutch kit and god knows what he did with the head gasket. I miss putting water on my golf...I loved the car. Hope the mechanic gets sued and goes bankrupt.
Hello just watched your video I have a mk4 2.0 it's a w reg I have milky on my oil cap my car uses no oil or water engine is breathing heavy when the cap is of runs very well I have cleaned some of the hoses out what could be wrong
That could be caused by moisture upon cold start ups. The moisture caused by combustion ends up as blow by and ends up on your oil cap. Now if you have oil in your coolant, that is a sign of a head gasket leak. Moisture can also accumulate in your oil because of blow by and create the known milkshake substance people fear as a blown head gasket.
My radiator cap looks a brown ish but the does not over heat also it looks bubbley
Wrong. It is oil that leaks into the coolant passages when head is blown 'cause oil pressure is greater. The first thing to check is the quality of coolant.
Hi pal, my golf mk4 2.0 has this under oil cap, but not as much water just foamy mayo, and the oil at dipstick is fine with no mayo! Coolant bottle also fine, how long will the car last if continued to be driven as is? And would a gasket sealant solve the problem? If so which do you recommend? Any help/advice is appreciated my man!
Thanks for your time :)
It could just be condensation, you will need a little more evidence before 100% confirming that is the problem. Is your car giving you andy mechanical problems for you to worry about?
Not that I know of? I have just dropped the oil and changed filter, changed coolant to g12, the foam takes a few days to come back once I clean it off? It has a strange smell sometimes when I smell in the filler, its only used twice a week or so for short journeys at the min but im wanting to start up a business and sign write the golf? Any ideas! Also do you recommend a gasket sealant that's safe if it is this? Many thanks
I don't really believe in gasket sealants so I personally would not advise it. The short journeys could be causing your problems, you may have more of a condensation issue rather that a head gasket. If you develop further problems, then I would suggest that you look into it otherwise just keep a eye on it.
Sorry for all the questions, but what problems shud I look out for? And if my car stays the same will it be okay to carry on driving as it is ( its a v reg ) with 104,000 on clock? Any main things I should look out for? Im fairly new to motors ive learned off your vids for my services, brakes etc...
Thanks again for your time/advice :)
Steve West hi there
i have the same problem with my octavia (i think the engines are the same) and i think may be is the head gasket gone. But i drive the this car almost 4 years(about 10,000miles) like that and still drives fine :)
Water in the oil? You mean oil in the water?
I have had the head gasket go on 3 of my cars so far. One of the other signs that I found was that there was loads of pressure when opening up the radiator cap. Thankfully the gasket has not gone on my VW but will pressure build up there on these too?
that's not completely true. it can just be condensation that got in the gas cap I have a car lot and that happens a lot need to pull the dipstick out check oil that way if you see milky oil then there's definitely a problem
The oil cap can be condensation! I seen two people put a head gasket in there car and a month later they see that and scream...
MMM.. OR MOANINMG SPECILLY WHEN YOU SEE THE WITHE MILK,,,, ITS FOR SUREEE THE EVIDENCE THAT WAS MISSING!1
Not true. It’s condensation. Most often happens on. An oil fill cap that is tube like in design.
Hey so are you a vw mechanic or do you just do this as a hobby?
A bit of both…lol
I have the same problem I hope to clarify the Maflt What is the solution to this problem
I wanna go for a road, trip. But just found out I have a suspected blown head gasket, could I do much harm by still going?
car has brown looking rust from radiator cap.. coolant does leak from under.. can by pass fix the problem
I have this on a 1.6 golf runs sweet but has a milky cap and quite a bit of water coming out of exhaust. it's been stood for 2 months so could it just be condensation from that.also quite a bit of vapour/mist out of exhaust
So... just replace the head gasket should resolve? I have the issue and don't know what to do...
Replace head gasket if only your car engine was overheating. Overheating also may cause by other parts. Please check on cooling system,sensor, radiator,fan,hose,waterpump,thermostat and leakage which will cost cheaper and easier to do before jump to conclusion of blown head gasket and replacing it. Unless your car is 7yrs old and above, you may do top overhaul which cover most of the problem and bring back your car perfomance as new. Top overhaul probably around $800-1k, change head gasket+skim head $500-700. If your car does not overheat, rather kept that money and do one time top overhaul. DIY should be below $200 replace without skim head(high risk + problem may occur again),send to machinist for skim add another $200-300 (depend on machinist price) , this is average rate or may i say common price for this kind of repair.
Not really it can just be condensation which VW are famous for having
I find unless you clean it off every month or 2 mostly in the winter months, There will always be some milkyness up there on the cap. It is normal on those engines. sometimes the seal on the oil cap isn't perfect seal and you always get some condensation build up around the cap and the lip of the oil filler especially if the car does short journeys. That stuff also gets sucked into and melts away the rubber pipe which feeds a valve back to the air intake too it's worth taking that apart and cleaning it on oil changes if needed.
However if you see that stuff much below the cap around the entire oil filler neck or on the rockers like on that example on the video. If it's around the dipstick too. There's clearly an issue.
its called emulsification .
I have this milky stuff! I drive about 2miles every evening in the winter and 2miles back at night uk wether no oil in reservoir and it’s not losing any coolant is this condensation or head gasket
PLEASE HELP. my head gasket went and has now been fixed. but the water bottle is still oily and dirty. does it need changing ????
0.20 valvoline oil will cause same condition
+jeramey wiley, Let me say bullshit on the Valvoline call.
I can tell if the car's farty sounding without much power, and shakey at low rpm and higher load.
I have oil i believe a light slush in my resivour, i noticed it last night but my car has never been out of water or oil and runs the same , really dont know whats going on question is do i drain my resivour and see if it returns? Dont mustard on my oil cap
Rule #1 the old cap is not a good text , because if I was selling the car I would take a cloth n clean the oil cap off lol
Sign of a blown head gasket = by a GM vehicle and wait 5 years. =) =)
I have a astra cdti and it just started to blow.white smoke from the exhaust could it be a blocked fuel filter or failed turbo?
VW watercooled lumps all get this. condensation, not blown HG. Usually caused by short runs. my wife's Golf 1,8T has worse than this for the last 5 years.....
i have this past in oil cap and my headgasket is ok. its condensation if you ride short distances in winter! in sumer i dont have this
Same thing here
My oil cap had bubbles it looked like chocolate milkshake
