Simple how-to: Replace Ford Focus PCV valve & hose, blown rocker gasket #1
HTML-код
- Опубликовано: 1 авг 2024
- Easy DIY how to: fixing a collapsing PCV hose on 2L 16V Zetec engines, a common Focus Mk1 problem, and replacing the PCV valve to ensure all possible related issues eliminated. These problems were identified after a rocker (valve) cover gasket blew, creating a major oil leak - failure of the PCV system can lead to increased crankcase pressure and so is a possible candidate cause.
The follow-up video details the fixing of the symptom by replacing the rocker cover gasket: • Simple how-to: Replace...

This Hella helped I would of not known about the collapsed pcv tube if I didn't watch this
Removing the air box first made this a 15min job!! Also, old book trick to remove stuck hose; use pliers & twist stuck end. You'll have plenty of room with the airbox removed.
Finally someone made a how to video on the focus before they replaced the value .Watched 3 video's on how to change the pvc value and tubing, but they already had it changed..Thought to myself how is this going to help anyone..Thanks for doing it right..
thank you for this video this was the perfect quarantine DIY. I had a plot twist tho. the front elbow with the valve didn’t wanna move. I finally put all my force, yanked it and it broke, with a quarter of it perma-stuck to the metal. spent the next hour careful scraping it off with a small flathead screwdriver in small chunks. 2000 ZX3 hatchback I’ve put 150k miles on. guessing it was the original valve and elbow 😂
Followed this one exactly. Only problem i had was getting the hose back on. Tried the blow dryer and pushed a 3/8 ratchet end thru the hole and heated it enough to fit on. Thanks for the video!
One of best car repair videos I've seen!! Well filmed and very well explained. Thanks Craig.
I went to replace my PCV hoses and valve today but saw that the PCV valve grommet had some cracks in it. Thought I could drive down to any one of three national chain auto parts stores within 5 blocks of my home and pick one up, but no one carries the grommet. RockAuto doesn't even carry the grommet. I hope Ford does! Once again, great video! I just watched your video #2 - valve cover gasket replacement - and it was also very well done. I really appreciate your videos!
Craig is a good teacher
Just bought this car to help me learn to fix things as a project thank you so much for the vids on the focus
Great video! The hose obviously worked, however every parts supplier keeps saying it's incorrect when I research it.
Excellent info, well demonstrated and methodical troubleshooting that every other video seems to lack. My car had been having similar issues as you and other commenters expressed. My pvc hose actually had a huge hole in it. I duct taped it initially and that lasted for few months, until it failed as well. The spring clamp i could not figure out what the heck was going on due to lack of line of sight, until i watched your video. Underneath was easier for somethings on the job but above from side after removing air filter box was good too but i found that from the left side around the throttle body was most effective, after removing a few small house lines that are connected directly above the hose at rear of motor. But as i an female,i have smaller wrists so i may be able to get hands in where most men could not. I have new exhaust manifold that i want to put on, as mine has crack in it, so i most definitely will be removing that to gain access to the actual valve, which i have yet to replace. Other vids say to take water hoses off to get to valve, that is a pain and is costly. Compliments to your maticulous engine compartment!! Never have i seen one that clean!!! Was like, oh, that's what it is supposed to look like!!!!
Great video, clearest details I've found and I managed a quick replacement without too much struggle. Also extra thanks for listing the part numbers - very helpful
I have a similar vehicle and this video is showing me what I have to inspect before replacing the cover gasket. Thanks.
Excellent video. What worked for me for rear connection was to remove plastic intake pipe and it frees up more space to get hose off and on.
The heat shield removal to get at front connection was genius.
Excellent tutorial, the way you explained relaxed me, have a nice day!
Huge help! Thank you so much! I had better luck getting the clamp off on the rear end of the hose from underneath the car when it was on ramps
The $3.99 Dorman grommet is an exact match to the $25 Ford part. Just did mine. Dorman 42059
I think this procedure is easier in the Zetec SE because it is an inverted motorization. The PCV valve and its pipes are on the front, they are much more accessible and easier to verify.
Most clear tutorial I've ever watched, both video and audio! Thanks was a pleasure to watch!
luz na mala da focus
THANK YOU!!.. what a Great THOROUGH Video!!.your narration was SPot On !!... THANKS AGAIN!!... look forward to your other videos..
Great video! Thx so much for posting. I did this job and found replacing the rear hose from underneath was much easier. Imho
Thank you this fixed my problem. When I would accelerate the car would lose power for about five seconds and stop oil leak as well good stuff
Excellent video and explanation
Thanks Craig
Great video. One small suggestion. Next time take the air intake off (pulls right off the throttle body once you loosen the clamp) and pull out the complete airbox. It'll give you much more room. The hose on my Focus was completely collapsed as well.
Thanks very clear and easy to follow .
well explained, you made it look easy,and provided useful tips
really well done video part by part shown as it should i will be changing myn tommorow as myn was exactly the same problem and same leaking place must be prome on these cars as well as the focus st170 thank you really help now i have no worries to change keep up these vide steve
i changed pcv valve by jacking up front of car, going underneath, wiggling it out with left hand, pliers, and flat head screwdriver, just be sure to not tug on it too hard or you'll break the hard plastic the rubber hose it attached to. it took 10 minutes.
Zetec is a great engine except for the known oil leak points. I have 290k miles on my escape and the cams show hardly any wear. Just did the timing belt this weekend and also replaced the front crank seal. Hoping for at least another 100k.
Question is the valve responsible for the hose collapse could it be ok if valve is replaced? I picked you because you're the most recent here. Ty. Ellis my number 2 cylinder is misfiring had auto zone check it..any suggestions? Ty my car is 2000 focus 62k miles engine looks replaced
@@ellismckinney4888 ford came out with a revised pcv hose with insulation around it to keep heat from softening it. My original hose collapsed also and it was replaced with the revised hose. I haven't had anymore issues with it in many many years
I would just replace the hose and valve since they are inexpensive.
@gregdittrich1206 thank you yes
Thanks Craig. Oh fine. Yes I have no problem doing that. Was just such a difference!! I might buy rubber in NZ, as has totally failed, and install that now. Ill clean valve while awaiting new one. Thanks again. David
I wish someone would do this on mk2.5 focus. This was so well explained (I would remove air intake though)! I suspect I have ether leak, or collapsing pcv hose.
excelente video maifrend!!!
Great vid!
This is what my problem is on my 2002 ZTEC motor.
Absolute legend mate
Thank you!
thank you!
Not too dissimilar to the 2003 1.8 Zetec petrol. Up until now I only thought that it was just the L or J (depends on how you see it? 😂) shaped piece of rubber pipe by the water pump. I guess I learned something new today?
Thanks for the info
That long PCV hose with heat-wrap and the molded elbow included is only $11.32USD on rockauto The elbow isn't plastic, but a synthetic rubber. It is very pliable.
Thank you I needed an inexpensive fix
Just changed the hose and valve myself, and I'd recommend that if you're going to do the same you be careful with the grommet the valve fits into. If you go to Ford they'll tell you that you can't get it by itself, it only comes as part of whatever the thing it fits into is, (Oil separator?) which is a $500 part. You can find out separately online, but it will cost you at least $20-30. I found one that kinda fit and made it work, but my advice would be to not mess with it unless it's obviously fragged.
Part # F5RZ-6A892-A for ~US$20 online. The grommet (plug) and also the plastic elbow on the other side of the valve are apparently common failures, though I had no issues.
I had the same collapsed hose on my focus. The car drove just fine but would idle really low and wanted to kill at stop signs. I cut the elbow, attached a new elbow at the end with a plastic "hose coupler". Idles/runs great now :) NOTE!!! This is a factory molded hose with one end wider than the other so get a plastic connector that has 2 different sizes on each end. If that nmakes any sense :P
Your'e the bees knees, thanks for the video
Thanks, I'm getting oil buildup before at the valve cover and now thats been replaced and its spewing out of the breather box where the pcv hose connects. This must be the culprit.
I had a bad pcv diagnosis and number 2 cylinder miss fire any suggestions? Ty great video
Excellent video Craig. Saved my bacon again! I was just about to change rocker gasket as per your vid and noticed the pcv hose is knackered!
I have a 2005 mk2 1.6 petrol - am i right in thinking the pcv hose is at the front of the engine, hidden away under inlet manifold and the hose itself is a lot shorter than on the mk1?
That hose clamp is evil. It turned a job that should have only taken a half a hour into a couple of hours. Would have helped if I could see it so I knew how it was suppose to work. I eventually got it by just squeezing it randomly with a pair of pliers.
Anyway, it's easier to reach if you take the air hose and throttle body off and go in from the left side. You can reach it without taking off the throttle body but you're going to cut up your arm. People are going to think I own a cat now.
I finally replace all the janky two-piece crap lug nuts with Dorman 711-305 for like $24 Real chrome, quality steel, no more junky caps falling off.
Your Ford wheel cap is missing. I just snagged a few for mine as two were not original with FORD molded into the plastic.😁
Wait a minute where can I find that hood latch grill key cylinder 😳 that would be killer on a svt
I have a MK1, and it JUST WON'T DIE. I keep thinking, next year when it dies i'll get a Subaru. But the damn thing just keeps going. Of course i keep fixing it when the random stuff breaks. only a matter of time before the head gasket fails though i suppose...
Will this effect vaccume overal? I get added fuel at idle.. and brakes don't feel very boosted.
Hi iv got a 2004 mk1 ford focus 1.8 in UK and just wondering if these parts will fit my car ?
Excellent I have a Mondeo MK2 2000 1.6 liter black engine
the problem the PCv hose not exist at all it seems it removed by the last honour what damage could happen if I let it like that
and if it cause a high fuel consumption what I would do
many thanks
Great video but you can take the air piping off and make it 10 times easier lol
Great video, have a Mondeo 2.0 estate (1998) that I use on occasion an it has this collapsing PCV hose in exactly the same fashion. Also the car will maintain approx. 2000 RPM when moving, even when clutch depressed, this only returns to normal idle when the car actually comes to a stop. Not sure if connected but every little helps, some would say..
No idea if that behavior is even abnormal sorry. But if the PCV hose is collapsing, it's not helping anything. Get it fixed.
Yep, my thoughts unfortunately the car is now back with those that use it more than me....will have a 'looksee' when I get it back again...How much was the replacement 'hose'??
About US$25. Amazon links in the desc.
Great many thanks..just one of my many 'projects'...
Malcolm Young did you change the pipe and valve? I've got the same issues as you on my focus
More videos on the focus!!
This one's gone I'm afraid, if there's another Focus it'll be a newer version.
Puede ser que se junte esa manguera con el servo de freno?
so im jealous.... why does your zx/2/3/4/5 have a dipstick for the transmission? mine definitely does not. i also live in the States
The PCV valve on my 2000 ford focus (mk1) 1.8L petrol does not close all the way when I blow in it from the Intake side. Is it designed that way or is it supposed to completely close off? it rattles ok so it's not stuck and it is clean
lol and i thought the pcv breather hose is the one that connects the rocker cover with the airbox under the air filter. tomorrow I have to check mine :D
It is, or the crankcase breather/ventilation specifically. There are two. The one connected to the valve is usually closer to the engine block and deteriorates faster.
Thanks for the video. Do you think that if this problem has been ongoing due to my lack of maintenance that it could create a case where oil is getting onto my serpentine belt. I know it is not the power steering.
The valve cover is certainly one possibility, should be easy to see, check around its perimeter.
@@CraigsDIY I think mine is unfortunately coming out of the crankshaft big time.
this is probably the reason why my zx3 has idle problems and stutters when I accelerate.. already changed throttle body, tps, plugs, wires, coil pack, and still idles like ass.. so im trying this next
Craig, do you know if the hose fits the svt focus? I've got an 03 SVTF and this hose definitely needs to be replaced, just wondering if it's the same part?
I think so because online parts checkers don't distinguish between the 2.0 L and any variant. But you should probably check - send a query to the seller (try the Amazon sellers, link in video description) or a Ford dealership along with your car's VIN.
Is the same on the 2005 ford focus to change the pvc valve
1.8 and 2.0 petrol should be similar. Specific parts might not be identical so careful ordering.
Thanks for the video ,mine 01 focus zetech2.0 dohc.. started jerking in front of stop sign when ac was on ...I changed ac compressor cleaned idle control valve now it idles it does it almost all the time when in gear even if ac is off sometimes backfires seems seems coming from cat area ....new spark plugs and wires compression is fine so time for egr.... When idles no jerks ....Do you suspect something else ? Thanks in advance
Actual backfires in the exhaust suggest rich fuel mix. Vacuum leak (e.g. PCV per video), MAF, O2 sensor, etc. Start with codes to see if the ECU knows something you don't.
Thanks for respond , no codes !!! Icon works
It was bad coil pack ....ohh I am so happy now...it did not give codes -weird !!! Thanks
I can’t get the clip off I tried pliers and a screw driver still nothing
Where to buy in new package?
Awesome this saved me a trip to the mechanic! I only replaced the hose which had a hole melted in it. Do you think I should change the valve too? It seems to be running good now.
Replacing the valve is a just a good maintenance item and not difficult or expensive, I'd replace it at the same time as a failed hose.
What are some symptoms you would encounter if this hose collapse?
james cerini rough idle and stalling is what I had
I've just encountered a weird, high and low pitch intermittent whistling noise from my zetec engine. My hose is like 200.000 miles old and is soft. Could this be the intermittent whistling issue noise?
A whistling might be an air leak. Anywhere in air intake system. You will have to track it down. Try soapy water and bubbles to start!
I have 2000 focus SE 2.0 Ztech DOHC and the OEM pcv valve doesn’t have suction on idle. Replaced it with after market that it did have suction on idle but the fuel consumption went up? Is OEM pcv valve doesn’t have suction on idle although it rattles?
At idle the valve should be near closed, but may not be completely. To see what's out of norm you will have to check if the engine is running lean, look at trims, or high idle. Also did you reset the KAM with the new valve, if it had adapted tune to the old open one the ECU may take a little while to re-calibrate.
Craig's DIY Car thank you so much for the instructions. I did look into short and long fuel trim and very high which makes me believe that I have a vacuum leak and P1131 but since my obd blue driver is showing high intake air temperature (41 C while it’s below 10 outside) I’m thinking that the EGR is the reason for a vacuum leak. I did reset the PCM.
Thanks a million
Hi Craig, it appears you are in NZ like me. Where the heck did you get Motorcraft Pcv valve at $25. John Andrews Ford just told me $157?? Rear hose $35...OK
+David Evans I wasn't silly enough to buy locally :) All these components are way cheaper overseas, even after you pay for air shipping. The Focus is common in the US and parts are peanuts. Search the part numbers I list above (verify your engine is in fact the same 1st) on eBay or Amazon.com and look for sellers that do international shipping.
Hi.
What year is the vehicle? I have a 2004 SE 2.0 DOHC, & when I try to order your same hose, website tells me it does not fit my vehicle. Thanks.
2003. You'll need to look at your existing hose and see if the part # is on it, usually it is.
thank you
I just replaced the PCV hose and valve, and when I started the engine I noticed the RPM’s dropping when I pressed the gas pedal. I looked, and the hose which connects the throttle body to the fuel rail (picture here: www.carthrottle.com/post/56m857z/) was broken. I tried taping it back, and the idle immediately improved so I’m pretty sure that was my problem. My question is what’s the hose called, where can I buy one and how do I replace it? Any helpful input is much appreciated
How does that valve operate? How do i know if its still good? If i blow one one side of it should it block the flow or not?
Yes it's one-way, but it's more sophisticated than that in the sense that it adjusts itself on a scale, which you can't test by blowing through it. So if it's old it's a case of just replace it.
Thanks. Removing the hose from the tube (ruclips.net/video/qR0f_yfBPTQ/видео.html) I was able to use a screwdriver pushing end of hose while pulling the other end. Stuck pretty good, that was the hardest part. Removing the large air intake hose (place rag over engine intake) gives a lot more access room.
Hose end at back of engine, access from underneath was way easier with car raised. Especially removing factory clamp. But more so installing new hose and band clamp. Old hose, there isnt a barb on engine nipple so it can be pried off as shown, just easier from underneath. The factory clamp easily released (ruclips.net/video/C0hX2ZMjEi0/видео.html shows the clamp and how it works).
Next is the valve cover gasket using you other vid...
I smell gas in this hose and see a bit of it ? Normal ?
If you have the Mk2 Focus, or any other car with the later Ford Duratec / Mazda L engines, see this video instead as it's a bit more involved: ruclips.net/video/-TR4pZdXZpg/видео.html
Just bought the Haynes Manual for my Focus. Only problem is my engine isn't listed. I have the 1.6 L Zetec SE (2001) 5 Speed Manual. Any idea what gearbox is in it? (it's a european sold car if that helps). Thanks, love your channel, great stuff.
Hi my car has a same problem. Can you tell me how much cost of this? And where from you ?
+jeewan pabla I bought online from the US. The hose is around US$25, the valve $10-20.
Are you living in Australia or somewhere else? I am in Sydney.
You're lucky you don't have the Focus 2.0 Duratec motor.
I just had my hose replaced and the intake manifold has to come off to get to it......$450.00!!!
BUT...on the bright side my motor has a timing chain and not a stupid BELT, so I don't have to pay to replace the belt!!
I do have a Duratec 2.0 in my own car. See my playlists and look up Duratec HE. I will actually be uploading intake manifold videos including PCV hose & valve over the next month or so. Now you understand this is a DIY channel right? You should be ashamed of yourself :)

5:43 im not gonna lie to you.. it's a piece of shittt hose, with a shity design, that wont come out that easly :D :D
Lol remove intake and battery silly
