My Engine is about to BURST! Volvo Redblock PCV System
HTML-код
- Опубликовано: 26 фев 2022
- Checking the PCV (Positive Crankcase Ventilation) system on the Redblock B230 engine and replacing the oil separator box due to too much pressure inside the engine. This one still failed the glove test even with a clean system, so further checks needed...

Seeing an involvo'd video being posted is now synonymous with a good day for me, don't know what it is about these, but you always manage to make my day!
👆👆
Thanks man that's really nice to hear!!
@@Involvod Your videos always go a long a way to reinforcing just what great shape my '90 740 GL is in. Which makes my day, too! Lol Keep them coming! :)
Really liking this channel. I'm quite familiar with 940's. They are bullet proof but if you neglect them for years you can run into a lot of maintenance jobs. The good thing is that they are simple engines.
Very true! I'm glad they are so simple, can't complain 😃
I don't think there's anything worse than replacing a part and finding out the issue is still there! Can't wait to see what the next video brings!
I know right! Thanks buddy
Ahh the good old PCV - I’ve done the glove test on all mine in the past. Always enjoy a new Involvo’d video
It's always a good idea to do one eh I need to stop leaving it so long! Thanks mate
I was told by older Volvo mechanics not to remove it because it often breaks the pipe on the pvc box that goes down to the oil pan. They recommended using engine degreaser or brake cleaner real good, then let it sit a bit and then do an oil change.
The ending 🤣 and the music 👌😄 Great vid, God loves a tryer , good luck 😊 xx
Thanks 😄
had this issue with mine, deleted the pcv and ran the holes to a vented catch can. made no difference, so bought a vented oil cap and ran that to a catch can aswell. fixed pretty much all the oil leaks from caused from excess pressure
Next thing I would check is the small diameter hose (that attaches to side of flame trap) for clogs and the threaded nipple that it connects to on the manifold. Hold onto your old breather box (for spare) and see if you can soak it and clean the internal deposits-a lot of the aftermarket boxes leak at the midpoint seam. Looking forward to see how this turns out.
Thanks for the tips! 🙏
The ending of the video is incredibly relatable. I've had plenty of times that I've replaced something on my 244, which ended up being perfectly fine and not the source of my problem...
Really frustrating isn't it! At least that's another thing ticked off the list!
@@Involvod I just tell myself it's 'preventative maintenance' and forget about it...
Ha! Another redblock classic ;D. Had also excessive pressure blowing everywere, eventhough I cleaned the PCV 6 months ago. Decided to relocate the PCV in more accessible place. Used some rubber hoses and plumbing parts to DIY it. It seems to work better now and I will propably change the oil soon too. Yeah. Years of neglection... Gotta clean that redblock eventually ;D
Wow, nice idea! Sounds interesting 😃
@Salamanda Ok. Maybe I will post some info on my instagram: wolwo240
"It's the thought that counts" LOL. The look on your face ... priceless.
I was genuinely grateful I just need to get the hang of it 🤣
Always a good start to the day to see a new video. I was crossing my fingers that it would be the PCV or EGR valves.
Looks like it will be a trilogy! My hopes that it won’t be anything too bad.
Thanks, I hope so too 😅🤞
The finger....priceless
The glove in the final minute is hilarious! Alt belt looks to need tightening. Love the channel and now subscribed as I have five 240's at present, two 544's and a 945. Always had numerous 240 throughout life. Thanks buddy.
Oh wow that's quite the collection!! Thanks for subscribing I appreciate that 👍
You have no idea how long we've been waiting for you to find that note! 😂
😁😁😁
Laughed out loud with you lighting the heater. Hilarious.
Its true. Fresh oil en filters keeps your car in perfect condition. But dont forget the coolant👍👍
I love learning new techniques with every video. I'm still fairly new to engine repair and all I've really done has been on a 93 240, so all these little gems you drop are invaluable. Thanks for another video!
Thanks for the kind words! Glad I can help you out 😃
Nearly as soon as I got my 245. I brought it in for a clean/replace PCV, IACV and FPR straight away. Huge improvment.
I was hoping at the end you had added the tune for Boris from Snatch.
It's definitely the smart thing to do! Haha, if I could've, I would've 😂
I thank you very much, I loosened my medlar and it turned out that the sensor was damaged and I replaced it
Glad to hear you fixed it 😃
I suggest oil change to shell helix petrol & diesel 5w40. Cleans piston rigns, or try engine flush. Even a good run on german motorway on full throtlle might help.
Thanks for the tips!
Good video as always mate. That shot with the glove reminds me of those wacky waving inflatable arm flailing tube men!
Haha brilliant 😂
Nice! You made it look too easy, either the 740 has more room than the 240 or you are a genius. Thanks for sharing!
Haha well I'll do it on the 240 soon and find out 😃 Thanks for watching!
Now that got me rolling on the carpet, Makita lamp as means of illuminating the whole scene, Haynes manual on the engine block, scrolling through it with - most likely dirty - gloves on lest the fingers might get colder than they already are...
You know how it is on this channel! 😄
1:47 The 1989 244 I once owned had a lot of blow-by.
When the PCV system plugged up unbeknownst to me the pressure got so high the engine pushed out both the front main and intermediate shaft seals.
I guess in hindsight it was fortunate the rear main didn't get pushed out, that would have been much more problematic.
Anyway;
I still needed to drive (thankfully very short) to work so for 4 days I put quart after quart of engine oil in as I obtained seals, a timing belt and almost every part of the PCV system right down to each hose.
I have the same Makita light, very handy.
That's what I'm worried about on this! Miss Involvo'd bought me the torch, it's great isn't it. We watch alot of Salvage Rebuilds here on YT, he has one!
@Salamanda Yah, it was a BIG mess!
i cracked the bottom of my oil pan a while back while parking, patched it up with some of that metal/glue epoxy stuff that bonds to metal, leak eventually came back so I reapplied it again but this time spent a little more time filing down the surface to get better adhesion, about 3 months later it was leaking again
turns out i have positive pressure in the crankcase which is why it keeps failing - it probably saved my engine
before replacing the pan i'll have to replace the pcv and clean/replace the hoses that connect as well as clean out the oil pickup and i believe there is also a channel from the base of the engine that feeds the pcv which easily gets blocked - not sure if the red is similar but perhaps that's why your repair hasn't turned out as expected
Thanks for sharing! That's really helpful. Glad you managed to get to the bottom of it. My problem turned out to be a blocked hose going from the nipple on the flame trap to the inlet manifold 🙄
3 years ago I went to the considerable trouble of removing the oil separator box from my then 29 year old 740 GL with the B230F engine. After more than 425,000kms I found it to be completely clean! Boy, was I pleasantly surprised! I guess that says a lot for only using top quality oils (Castrol, Quaker State) and filters (Volvo, MANN) and never running more than 3,000 miles between oil changes. :)
Yeah that'll do it! Very nice 😃
@@Involvod If you enter '1990 Volvo 740 GL Walkaround' you'll be able to view the 4 short videos I uploaded just today. If you enter '1990 Volvo 740 GL with B230F Engine' you'll find the engine running video.
@@bobjohnson205 I just watched them and left a comment, that's a really nice one you've got there! Great colour!
Learn so much from your videos I actually want a Vovlo
You should get one 😎 Thanks mate!
I've watched this video again and the next one .You've given me the inspiration to tackle mine now I have finally got my 240 back from the incompetent Volvo specialist!!!
Loved the how you ended the video. Still laughing. Looking forward to final fix.
Thanks 😃
Ah the ending was hilarious. Maybe need to replace the two hoses as well? Thanks for these videos going to replace my pcv for the first time on my 328,000 kms turbo redblock
Exactly, I replaced the little hose in the following video as it was totally blocked! Good luck with yours, it's not as bad to do as it looks!
8:26 Mechanic moment, then u drive with the car without thinking of the problem for some time then fix it when u calm down
👏👏😄
Oh that cliffhanger! I'd check the lower breather tube as mentioned above. How's your RMS doing with all that blow? :) Usually the catch can does not need to be replaced, soak it over night in diesel and its as good as new.
Well I've recently noticed the front one leaking 🙄 Thanks, i'll keep the old one and give it a clean, especially now we know that it probably wasn't totally blocked!
@@Involvod yeah that's a great spare! Oh well, that's a nicer job to do at least, and you'll get an incentive to do the belt! Seem to be a bit of a lottery, in most B230's i've had, previous owners have done the front seals when doing the belt, so the RMS goes when the fronts are fresh and the PCV is clean.
Neglected/Restricted air filters may also contribute to high crank-case pressure.
I’ve watched and enjoyed all the previous videos. Completely up to date with watching and waiting for the next video to come online. Like it a lot. Think Volvo’s are well build cars. And like old Škoda’s you can pretty much repair everything yourself.
Thanks, I really appreciate that, that's alot of videos! 😃
Stay away from flames is my advice..lol.
🤣
I thought that your beard was a goner when the fire burst into flame. Don't worry, you will get the problem sorted.
🤣 Me too
Did mine on my v70 T5..Annoying and time consuming job but the engine is not blowing.. Perhaps you're going to have to clean out the rubber pipe or replace it.. Its also a good idea to clean out where the pcv box attached to the engine..Maybe try running a good flushing agent like liqui moly apparently it works well cleaning out built up deposits..Good luck mate.
Thanks mate!
У нас это называется САПУН(возможно от слова сопеть - пыхтеть, травить газы во сне храпеть) и то что ты его заменил, а давление картерных газов осталось - скорее всего какая то трубка внутри закоксовалась и наглухо перекрыта(честно говоря ожидал что на видео ты промоешь старый САПУН и заодно все трубки и штуцеры соединительные, ибо у меня даже на турбине как то встретилась намертво закоксовавшаяся трубка слива масла с турбины, а она диаметром 2 сантиметра почти и ее не сразу пробил даже сильный растворитель). Так что мой тебе совет - проверь все все трубки и соединительные отверстия под них, промой все растворителем, почисти впускной коллектор с его трубками ваккуумными. И еще то очень нехорошо восьмеркой играет ремень генератора, быстро сотрет, да и ток он не настолько эффективно вырабатывает, надо поправить и натяжение и выровнять)
Thanks for the tips! 👍
@@Involvod You can read that?
Google translate :D
Is that a yes?
Supervideo and great explanation
Thanks, glad you enjoyed it!
@@Involvod One idea; what if the breather pipe itself is blocked somehow?
It seems a bit worn engine. Breathing out some combustion air from top or bottom, or both like valve sealing surfaces, valve guides, piston/cylinder sides, piston rings. Cheapest try could be some diesel flush as a motor oil, could release some build up on the piston rings and make it seal better. However that is not the worst blow by I have seen.
That's true! I'm going to do some extra tests on the engine and see what it tells us
Hells Bells! That ending!
Can the pcv be deleted in a sense, or replaced by a better system? Seems to be a weak point on these redblocks
That's a good question, I'm not sure, might look into that!
That was funny at the end.
Tragic outcome, dammit. Final inflation leads to total deflation. Only temporary I'm sure. Keep smiling !
Yeah definitely, we'll get there!
This work at redblocks is much easier than on a 2005 S60T5 or Volvo V70 II.
yep exact problem with mine also! i did the box and trap but still had that problem, to be honest i just left it after that 😬
Have you checked the small hose that goes from the inlet manifold to the small nipple on the flame trap? Sometimes that gets blocked too!
@@Involvod oh yeah! I forgot that's blocked!! Hopefully I can use some carby cleaner to clean that out haha, thanks for reminding me! Hope your brick is all sorted now!
I think your high crank pressure might be due to rings sticking due to naff oil being used!!! One thing to be really careful of is the oil you use in a turbo engine, as the turbo is exhaust driven the heat build up is massive, if anyone just turns the engine off after a blast the oil 'cooks' in the turbo and restricts the oil drain. The oil drain restriction causes the flow to decrease and eventually kills the turbo. Synthetic oils can stand the high temps in turbos so much better. Don't even look at semi synthetics as they are just mineral with a splash of synthetic - just marketing bull.
Hopefully high crank pressure is due to ventilation system not stuck rings! Good Luck.
its NA
Thanks, that's a good point I might pick up a synthetic oil for the turbo, totally true about the semi synthetic, I think I remember hearing that there's no regulation on how much synthetic oil has to be in it, so yeah, can be just a drip!
@@pelayorico This one is but his 940 is turbo.
Its a common issue. If the car has lots of mileage, the rings are getting worned. Compression goes through the pistons.
Hopefully that's not the case here 😬
There's a tube going into the sump. It could be blocked as well.
Thanks, that's what one of my friends said too, I reckon I'll leak test it, then if it's okay, take off the sump and check that pipe!
@@Involvod check the compression first, i guess. you could have so much blow-by that the pcv can't handle it, or something. i'm not a specialist, all i'm saying is you should think of and check other things that can affect it before putting effort into it.
@@zloychechen5150 that's what I'm worried about 😅
What's that clankity clank your water pump? Oh how I love mechanickin' xD
Was the flame-trap housing connected on all 3 sides?
On mine the small diameter nipple was broken off and leaking vacuum. Bought a new housing and after connecting everything properly my crankcase pressure went from positive to negative. If you rev the engine up and crank case pressure goes from positive to neutral or negative at slightly higher revs it's an indicator for a vacuum leak.
Edit: Crossing my fingers for you it isn't blow-by
Yeah I checked that and it was okay, I've had that issue before though! I will try revving it up a bit today, thanks for the tip!
IMO the blowby is actually not too bad. I mean, i have seen way worse. All engines have SOME blowby.
You now know for a fact that the PCV system is OK. Now just run it.
Also, to be fair you would have to test the blowby at full operating temp because only then will all parts (block, pistons, rings) have expanded fully due to heat.
Thanks, I did make sure it was hot I should have mentioned that in the vid. I'm noticing the oil leaks getting worse, but if it turns out to need engine work I will just keep driving it for now, she runs good
Grüße gehen raus!
Do you ever get the feeling if it weren’t for bad luck you might not have any luck at all? Hope this works out for the best.
😂 Thanks!
Hello my friend, which country are you from?
Hey! I'm in Germany, but from England!
Can somebody tell me why there is at 6:29 no second ring mounted on the left side?
It's because it slides into a rubber tube in the block 👍
If I did that with a glove on my wagon it would flip me off
ist bei meine sauger auch so (verlieren kein öl). Liegt vermutlich daran das man im leerlauf keinen wirklichen unterdruck hat beim sauger.
Ugh on the PCV situation…I did notice though it looks like your drive belt is a bit floppy as well. Perhaps it’s on the list to be changed?
Yeah well spotted! I cut that part out, I'm surprised it doesn't make any noise flapping around like that!
🤣🤣🤣🤣🤣🤣good ending
My 940 keeps overheating, the only thing i haven't changed is the water pump.any suggestions
Love the channel, would my B230E KJet engined Vulvo have one of these fitted?
I swapped out my pcv and flame trap and flame trap hose with new ones, and cleaned my MAF, but still filling up the glove. Any ideas???
Did you replace the little hose as well? In the video after this I find that was my problem. It could also be excessive blow by from the pistons, or there's a pipe that the pcv fits into that goes down into the oil pan, if it breaks it can cause problems, the sump needs to come off for access
@@Involvod my little hose is stiff af but clear. The intake manifold nipple it attaches to however is very clogged up, can hardly see into it. Will unbolt it off and clean that and pray.
@@WildlandsGG Fingers crossed for you! The whole thing really relies on that vacuum being clear
@@Involvod changed the tiny hose, cleaned the nipple, and the glove freaking SUCKS now!! Freaking stoked. Your video helped tremendously.
@@WildlandsGG awesome!! 😁
Vaš video mi se jako dopadaju
Thank you 😃
I can't believe its fighting you so much. Isn't it happy to be saved?
You'd think so! The engine was supposed to be the one problem free thing about this car 😅
@@Involvod thats what you get for thinking positive LOL
@Salamanda *ACCESS DENIED* LOL
@Salamanda showed up to party but youre at the wrong address lolololol
Where do you live brother?
I'm in Berlin!
What if it sucks the glove with a lot of suction?
10w40 is semi synthetic oil, right? Or is this full mineral? I guess cars that are around 30 years old will have run on semi synthetic as it was very common back then too. Or am I wrong?
This stuff is mineral, semi synthetic would be better, but there's a bit of a question as to how "synthetic" a semi oil is, because there's no requirement on how much it has to be, it can be just a drop, a quick Google search said it could be 5-10%
I'm sure that premium brand oils will be a good portion synthetic, but this oil I use is €20 a can which is great value for a premium oil, the redblocks seem to love it, so I just stick with it. I'll probably find some decent fully synthetic oil to go into the 940 turbo though when I do the head gasket.
Had this issue with my 2.5t v70, scared the shizzle out of me. Anyway, i think they only blow out the freeze plugs when the pressure gets too much?
Maan what an unexpected end to the vid, i was gutted too.
I'm not sure about the freeze plugs, but there's a leak from the front crankshaft seal which is getting worse and probably more seals to follow 😬
Maybe in the meantime you just got it fixed. If not I have figured out some interesting details. Below the oil seperator box there is a hose going down to the oil reservoir. On my Volvo 240 this hose is nearly full of debree too. In this video someone refurbish a motor and you can see clearly where this hose is sitting. Maybe you have to clean this hose too?
ruclips.net/video/GIVhKtua8s4/видео.htmlsi=dFDAWF3qalB8omQQ&t=1892
And in this video is a short sequence where you can see inside this black box. If there is any fluid to lose all the debree it should be possible to clean the box instead of buying a new one.

What percentage of fat is suitable for a Valvo 940 .?
I'm not sure what you mean? 😃
Bro! That was funny hahahahahahaha fucking PCV system. Hahahahahahaha
Bro check for clogged hoses!
Does the pressure arise from exhaust valve leak-by ?
Yeah it could be, or maybe past the piston rings etc, I need to do some tests 😏
@@Involvod I SO look forward to your uploads.
@@danielebbeling4056 thanks! Just realised I made a mistake though, the pressure in the crankcase must be from blow by past the piston/rings, but exhaust valve leak by would definitely cause a loss in compression
and flush with wynns engine flush before every oil change
I've never tried an oil flush, heard the horror stories about them causing problems, I take it you haven't had any bad experiences?
