welcome to my channel if your new here remember to like and subscribe👍in this episode we will be testing different ways of stopping the oil cap from bouncing and being under some sort of vacuum unlike the first vid when we added a pcv valve in the system with a catch can. but will it make any difference this time ?? - ยานยนต์และพาหนะ

fair play for taking the time to test it all out mate, we have all wondered and now we know! great work!
cheers mate this has been doing my head in to what is right , wrong or just normal? you've had many TT's what do your 1.8t do ?
did u ever find out why the inlet manifold wasn't sucking enough@@CarChris82
Luv it mate, another great video. So, after watching this pt2, I stand by my comment on pt1. You can also try a weaker spring in the valve which would account for the extra pressure caused by the addition of the catch can.
Just checked my S3 (BAM engine) on standard pcv system (albeit nearly 21 years old) and it did exactly the same thing. Only other mod is the N249 delete 👍
Hi Chris ! Old video, I know.
I have done exactly the same install as yours , BAM 225 2001.
I found the same catch can on ebay or something ( chinese I guess )
What I did yesterday was to bypass the catch can, direct to the pcv, and then no more bouncing.
Seems to be a simplified install than the OEM one.
So , probably, the can is the culprit.
Why ? Don’t know yet. Maybe too small, maybe to far.
Next will be to replug the can without the grill inside.
Hey, my audi tt mk1 (engine swapped with a cupra 1.8T 20v AYP and tuned to 300hp with K04 turbo) was smokin/burning oil at low rpm (
Worth a try well done
Cheers mate 👍
Put the T piece with the PCV valve in its original spot under the intake manifold, near the spot where the original elbow comes out of the crankcase, before the catchcan with shorter hose. This how i set it up and its working fine.
Love a dancing cap! I never even thought about the extra weight in the billeted cap making that difference. Great detail on the mesurements mate. Stop vaping with those valves! lol
Lol whats your 225 doing mate bouncing cap ?
@@CarChris82 Maybe i should start it and find out? lol
@@andycharger I just put a poll up on comunity page
Hi Chris, I have completely standard PCV/PRV system with catch can added in between rocker cover and PRV. Cap is not bouncing only when there is no middle section between cap and engine.
I just put a poll up on comunity page 👍🏻
Belle vidéo 👌 😉
👍🏻👊🏻🔥🔥
@@CarChris82 👍 😉 TT 👍 😉
I change pcv valve for first time at 80k km before 2weeks oil cup stop dance….but my oil is 200ml lower after 2weeks and oil cup no dance also no oil on turbo I change it because of oil in turbo…idk delete it?or engine must burn some oil like Audi say
I have catch can installed its vented to atmosphere and my oil filler cap still bouncing is showing on the boost gauge when off the throttle that i have too much vacuum
My old 225 used to have its cap bounce with the catch can, but then that block had blow by and lots of other issues! 😁 Interesting to see that even with the PCV valve in you still get the bounce - I reckon you're right though that the idle vacuum from the manifold isn't strong enough - is there a better place to maybe pull the vacuum from?
Hi mate I fitted the valve where the oem pcv system pulls vac from ive not thought about where else for it to go as thats the vacuum source. I bet your glad you have the 3.2 now ? What does the 3.2 cap do out of interest 🤔
@@CarChris82 haha yep! You know I’m not sure, I’ll have a check tomorrow and see what it does. I’d love another 225 though, a coupe, at some point
@@benofthenorthuk sounds good mate 👍 you can never have enough TT's 😁
@@CarChris82 My bank balance says otherwise 😆
@@benofthenorthuk 😂
Same setup as you with 034 exactly the same outcome. But i have more pressing issues think i bent valves due to a timing chain issue. Find out next week when i crack the cover 🙄
Bad times mate I hope its not ad bad as you think
I just put a poll up on comunity page
negative and positive pressure in the head is to be expected, this is normal and you wont be able to stop it completely.
Hey again Chris remember when I mentioned about filing the relief cut? did you try that?, whats the ID of your hoses? also from the looks of it you have your PRV in the same tee with the PCV is your PRV working ok?
Hi mate yes I remembered and made the relief bigger and it did make a slight difference for the better
I just put a poll up on comunity page
I have standard OEM PCV system only the SAI is deleted and it's bouncing the same. And it was the same before the delete. When I push the oil cap then it stops to bounce and then sometimes it starts to bounce again after few seconds.
I have readed that to much suction is also not good, but then my question is what is the normal amount? :)
Just a little I think but I don't know if thats the right answer I think everyone's is different due to set up and engine wear
I just put a poll up on comunity page
Chis it really makes no difference . At idle the turbo is generating so little pressure the excess back pressure is able to escape around the turbo blades, Also in your system the spring in the one way valve isn’t weak enough to open, so what’s happening is pressure builds- valve opens - pressure drops valve closes and the cycle keeps repeating. Really at ideal does the engine really care about the pcv or pressure in the rocker cover as it’s so low. Maybe a better setup is just vent straight to atmosphere. So any blowby can just be expelled under the car.
Your right mate I don't think it really matters that much as when your driving it all gets pulled through.this was more of a test to see what happens and if you need a pcv valve in or not with a catch can set up
I just put a poll up on comunity page
PLEASE COMMENT BELOW WHAT SET UP YOU HAVE AND IF YOUR CAP IS BOUNCING
I HAVE JUST PUT A POLL UP ON THE COMUNITY PAGE IF YOU COULD GO VOTE AND HOPFULLY WE WILL GET TO THE BOTTOM OF THIS AND FIND OUT WHAT IS NORMAL 👍www.youtube.com/@CarChris82/community
I don’t think mine bounces like that but without valve fitted it’s sorted .. ya look like ya blowing up a balloon 😂👍
Go and have a look and let us know what yours does ? And what set up you have
I'll check mine later. I've just bought a catch can set up and waiting for it to arrive
Hey man, did you solve the problem? I have the same exact problem with my 2001 VW New Beetle 1.8T,
I've replaced the pcv, the pcv lines and the pcr and still my oil cup jumps
Some just do it mate, every engine seems different must be how worn things are
Hey Chris, i just checked if the cap of my engine is dancing and it does! Its the bjx 1.8 20vt with standard engine with only a stage 1 tune. Is it bad if the cap is dancing? Should i fix this? Thanks for this video it allready helped a lot! (Sorry for bad english)
It might be worth checking the pcv system and valve for a split in pipe or blocked valve 👍🏻
Is that pcv valve not normally under the manifold where there is more vacuum?
Yes mate mine is connected to the same bit just further back have a look at my first vid on pcv your see how it rigged up
I will change turbo all of this start after rebuilt turbo
OEM PCV with new PCV lines and walve. Cap is bouncing.
Thank you for letting us all know im starting to think this is normal
I just put a poll up on comunity page
Chris, what's the purpose of your test? Is the cap bouncing a bad thing and a problem that needs to be solved?
Yes it means that the pcv is not working as it should 👍
@@julesmatthews2178 so. If this was a brand new car like back in 2002, the cap wouldn't do that with standard pcv system?
Is adding the catch can the problem?
@@benjames6929 yeah your probably right. I I’ve all new pcv pipes and new 034 valve and I asked bryn if it’s worth fitting a catch can is words were no it’s fine as it is . I appreciate that it pulls the crap out of the pcv into the canister but I change my oil an filter every 4/5000 miles 👍
Changing your oil makes no difference to what a catch can does,it removes the c**p from going back into the intake
The purpose of the test was to see if putting a pcv valve in the system with a catch can makes any difference to not having a valve fitted as a lot of people including myself run without a valve but others say you should have one did you see the first vid on this ?
I have a catch can and no pcv valve and my cap bounces
Thats exactly how mine was mate I think its normal without a valve but even with a valve seems to not make much difference
I just put a poll up on comunity page
I’ll say now and I’ve not seen rest the OEM will be better
Oem don't have a catch can also this is simpler and easy to swap out
@@CarChris82 but was surprised there was no difference in OEM or 034 valve .. I’ve got new pcv pipes 034 valve no catch can . I asked Bryns advice on fitting one he said no yours is fine as it is . I’ve a good idle not 100% more 98 👍
I have perfect idle too mate just want to see what others caps are doing as its very mixed in people say its normal and others say there should be a little vacuum
@@CarChris82 think you get more vacuum when you rev it 🤷🏻♂️ . Mine doesn’t suck down as strong as yours did with your valve not fitted but I’ve definitely got vacuum it pulls oil cap down .
@@julesmatthews2178 yes mate when driving it get vacuum from the tip pulling it all through
Tried my wife’s mini cap today standard 1600 Cooper guess what it dances just like my bam with can fitted 🤷🏻♂️ phoned are kid up he’s got golf 1.8T standard not played with asked him to do the test yep it dances lad next door bmw z4 guess what no dancing 🙈 I’m done life’s too short 🤣🤣🤣
thanks for the info mate I just put a poll up on my community page to find out what is more common👍
I have the same noise coming from my 3.2L vr6 TT could it be the same issue? #loveandHUNDREDS
What noise ?
@@CarChris82 it was my belt. Replaced and problem fixed + #loveandHUNDREDS
