That's just you running rich if it's a dark exhaust.

thats what i thought but even at idle it will do it sometimes.. to rich im assuming

It's probably a small thing like blowby and if it is blowby than just buy an oil catch can. If it's the headgasket change your oil and look at it and if the oil is a little milky than your headgasket is done. Also you can do a compression test on your motor.

Could be your oil seals in your turbocharger a buddy of mine had that happen to him not too long ago he was told since he ran full synthetic that he did not have to let the car cool down after boosting to shut the engine off i know i know he was stupid and didnt listen to me when i told him to get a Turbo Timer because he is impatient... but none the less he would boost it up his long ___ drive way and then shut it right off. No Cool down process at all. You have to let that turbo cool down to normal operating temp if not the seals will expand during heat and then constrict so tight when the car is just shut off immediately. But thats just a guess here dont quote me it's just my buddy's car was doing that exact thing when his turbo oil seals went |
thats probably what happened to me.

Do a compression test and then a leakdown if you find you're losing compression. leak down, and copression check first, then turn down the boost until you set up a proper vented system to eliminate crank pressure. this is something that the honda world is doing now which is adding extra vents in the VC and routing it to a catch can with a breather on top to fix the issues. |
I'm glad I found this thread!
I'm running at 10PSI on my supercharger and recently installed the modifications to my supercharger intake. With those changes I put in the valve cover filter, removing the recirculator hose. I now see a tiny bit of smoke coming out of my hood, from the hood vent that sits right above the valve cover. I don't see it all the time, usually after high RPM's or agressive acceleration. When I did take apart all the stock piping/hoses for the intake, I did notice a small build up of sticky/dirty oil on the inside of the pipe with the rebreather/valve cover hose. I'm at 85k miles (45k of those have been supercharged) Should I start with compression testing to see what to fix/upgrade/reinforce first? |
had this same problem and connected both breather valves to the catch can and just put a breather filter on the catch can. Stopped smoking but will every once and awhile after running it hard

If you have smoke coming out of your valve cover breather hose or if smoke comes out of the dip stick tube, when dip stick is pulled out and car is idling, your rings and/or ringlands are shot in at least one cylinder. Do a compression test immediately and start saving for a rebuild. There should never be that much blowby and just installing a oil catch can will not solve your problems; you will still have bad rings. A 2az in good condition will not require a catch can because there should be little to no blow by whatsoever.

As for a turbo timer, it really isn't needed. Yes, there is such thing as oil cooking the seals by letting hot, uncirculated oil sit in the center cartridge but a turbo timer does not do much to help this. If you moniter oil temp with a gauge when you cut the engine off and after the turbo timer has cut off, there is practically no difference in temperature, thus meaning no difference in helping or hurting a turbo'd car with or without a turbo timer. I think import tuner tested this in an old issue as well and proved same results. Any decent turbo shouldn't be affected by the temps we introduce them to in a mildly boosted tc. Oil temps should not get that high. |

If your engine is smoking that bad and nothing is coming out the dipstick tube then I would believe you have valve seals going bad. Did you notice any smoke from the exhaust? Check your pvc valve also.

I had a similar issue and it ended up being multiple cracks on a ringland. Do a leak down test for good measure.
