3b20t intermitant miss at WOT.. ??

The tight spot dont sound right, if the wheels make contact with the housing bad things happen. Or it may just have been a bit of dirt/carbon in the exhaust side. Having said that the turbos are a sleeve bearing so in theory the shaft floats in a film of oil, without the engine running and oil pressure it may move offcenter enough to bind up on the carbon deposits.

Generally speaking its best not to drill the airbox as it will suck hot air from around the manifold/turbo, the more fresh outside air you can feed it the better.

opened exhaust side of turbo today and removed wastgate to look at what comes before hand.. no oil in manifold and for what i can tell there is no oil residue in the exhaust either. im not sure about turbo now, but that tight spot that i DID feel a good few times is playing on my mind!! ? . removed breather hoses today and LMAO!! hose from t-peice at rear of head, the one comming from t pice to the plastic one way valve at rad side had completly split.. OIL EVERYWHERE!!! . also this " one way valve definetly is not a one way valve any more either. clean trough from both sides, and infact even the ball is gone.. have pics of both pipe slit and dud one way valve.. enjoy .. i still having trouble getting my head around how it could make it smoke quite alot.. less than a week and i have her in pieces lololol.. infact second that if any one would like to explain how i put pics from computer to forum i will put pics up asap..

So how bady could this make a 3 b run ?? and smoke? it was also getting unmetered air after the maf if im correct seing at the steel pipe is under vacum at cold side, right ? i hope this is my smoking problem!!!

presumming 1 is at pulley. 1. 11.2 bar
2. 11.4 bar
3. 11.0 bar
4. 11.5 bar
5. 11.7/8 bar. test was done after engine had ben run for 2/3 minutes litterally. will do proper cold test tommorow. are these results any good????

When I bought my 3B S2 I knew the car had split breathers as I could smell it when driving. Before buying the car I found the split and and thought It would be easy to do. ANyway everytime I tried to floor it the car would violently cut power throwing me forward in my seat. I replaced the pipe with a genuine one and then spent the next few days replacing the next hose/seal that gave out. After a couple of days I had resolved all leaks and what a difference to power and smoothness.

i hope so my friend.. gonna do some cleaning tomorow maybe take the intake off and dizzy and renew both. the car was doing things similar to what you describe.. i just had another look at the turbo elbow and to be fair most of the oil that was in it is from the steel breather pipe. so now im thinking that this one way valve failed she started to put oil through breather, eventual deteriated pipe with oil, then it split.. im gonna take the intercooler of tomorow and see if its full of oil. maybe theres some in there. need to get a second opion on those comp figures tho.. 164, 167 , 161 , 169 , 171 psi . is it possible for valve stems to make an engine smoke constantly? i need to know if bores are worn as i have here striped this far. thanks for reply

9-13bar is the factory spec, and your results are close enough to each other to call it healty IMO.

good luck with it. cleaned em all out and touch wood my has car been fine. never uses oil and not missed a beat since.

There will always be some oil getting sucked out into the intake so intercooler and intake hoses will usually have oil on them, but not enough to matter. To be honest i would sort the breathers and fit a new valve and see how the car runs before getting worried. Valve seals can leak with age but unless the car is high mileage its rarely a problem. Its far more common for the turbo seals to start weeping first.

In short fix the above and pressure test the intake system, it will be a different car to drive. Also have a search for the markh mod on the forum before you strip off the intercooler, infact i would say just buy the reducer and fit it anyway while you have it all apart.

feel alot better now thank you. *** cheeks have been firmly clamed all day long whilst ive been taking bits and bobs off, been praying the bottom end wasnt fooked, good clean tomorow and another few pics for ye guys and a few more hours to think about my next steps... 25 year old trying to restore 21 year old car in "ireland" isn't easy at the mo if ya get me!! sound for the good news .

Where is this flame arrestor ive read about located? in which pipe ? nice little job for the morning if i knew where it was??

[stocious]

what should be inside this pcv valve the one ive shown in the pics.. im baffled as to how it works, worked. i can see a spring but there is no other moving part , and a clean blow through from both sides??
