Question, my car when it sits for more than a hour or or in The morning (smokes comes out steady for 5 mins in the morning) blows a big cloud of whites smoke (worse when it sits for a long time) after that It is gone. I have Rob Becks upgraded valve and new check valve and have a BMS OCC. When driving there is no smoke?! Any ideas? It seems more from the passenger side exhaust so it seems bank specific. I have been told it is CCV system, I was thinking maybe oil on the turbo while it sits overnight. Car runs great...boost to 17-18 psi.

CCV? I take it you mean PCV? Some light smoke on startup could be either oil building up in the turbo inlet pipes or perhaps a little exhaust valve guide seals. Do you have RB turbos as well?

Noe CCV (crank case ventilation). Okay that makes sense with the inlet pipes, but wouldn't the smoke be bluish?

not yet, but soon.

No not necessarily become bluish. It could be the CCV. How long have you had your RB's on? I barely see smoke and thats very very rare. Basically I know its from not having an OCC but I just dont think its that necessary. It might filter most of the oil but no matter what, when it gets hot especially, its going to find a way the tubing/piping. I have had my RB's for about 9500 miles (roughly) and I dont get any smoke. It might have something to do with what oil/weight you use. I recommend you staying with the factory BMW oil honestly which is their Castrol 5w/30. I have seen some people use 5/40 but their car also smokes occasionally or sometimes when they come to a stop light or just sitting at a stop light. And you see it more on the right side because its more of a straight shot from the downpipes rather than the driver side that has more bends ect.. You should be fine man and honestly I could not be happier with them. It drives just like stock turbos without that stupid wastegate rattle and boost is almost instant and it def can handle more boost than you are running

^He doesnt have RBs, neither do I and i have the same exact problem..

No RB's yet...I run 5w/30 and have a Stett stage 2 oil cooler with 180 degree thermostat.

was this condition occuring before the oil cooler install?

Actually not as bad, it started about 2 months after when it got a bit hotter I believe....here is a vid....noticed it does have water coming out of the tailpipe, coolant level has not budged, oil level is not low and on target also...have log if needed.

Here is the vid:

[robc1976]

It only does this when it sits for a hour...I know when you start up your car in the morning it will do this....but mine will do this if say I drove it for 2 hours, let it sit for a hour and started it it will smoke with in 1-3 minutes. No sweet smell, no oil smell really. I have kitty less Dps and a resonator delete.

[MilehighM3]

Do you perhaps have a boost leak that may be causing oil to build up in the intake?

[chris b.]

looks as if oil is pooled somehwere. once you get flow it clears up?
idk just guessing....
no smell at all? weird.....

Boost is right on target, would it help if I posted a log? I also have a BMS OCC. no oil blow by that I see in the charge pipe either. Valves where cleaned 6,000 mile ago.

It's the Rob Beck Positive Crankcase Valve (PCV) Upgrade. Here's the thread on one of the other forums that confirms it's a PCV Upgrade: http://www.n54tech.com/forums/showthread.php?t=15382


The smoke is from being 100% kittyless. The exhaust takes longer to heat up & burn out all the condensation that builds up in the exhaust piping from the turbos back. Once you turn the car off, the exhaust cools off (cats take longer for temps to come down) and the exhaust vapors condense in the exhaust piping (so when you start the car again, starts the cycle all over again).

If you want this to go away, put your secondary cats back in

Once I drive away it clears up...I could sit at a stop light for 2o mins and nothing. I do have a slightly leaking valve cover gasket, I do get a small amount of oil on plug threads....plugs are in great shape with no oil on the electrode.

Also could this be the cause: (sorry for the link...posting from iPad)

I have the upgraded valve....it doesn't bother me enough to that lol!!! I do have secondary cats, I have kitty-less Dps. Why did it not do this all the time and just started all of a sudden?

I think you actually may be correct...it did not start doing this until it got really hot outside....didnt do this in cooler temps?

I'm gonna say you don't notice it in colder temps b/c any exhaust vapors freeze in the pipes once you turn the car off. So when when you turn the car on those frozen gases need to defrost & at that point they are either kicked out the back as a liquid OR the exit as a gas while you're motoring around.

So now that it's hotter out (above 32 F), the exhaust vapors remain in the exhaust pipes in a liquid form, so when the engine does get turned on they get turned into a gas much faster (making it more noticeable from a cold start).

I think you figured this out man.....awesome info!!

Same thing for me. Smoke only at idle and when car is up to temp. Once I move, smoke is gone.
