Hey guys so this my become a bit lengthy but I will keep it as short and detailed as possible. I am fairly new to the BMW world and struggling to diagnose an excessive white smoke on start up along with slight smoking at idle.
For starters the car is a streetable drift car. I drive it on the street and abuse it on the track.
Engine:
M54b30, around 120xx miles on the engine. I swapped this engine into my 330i because when i bought the car it had a junk head and it was easier just to replace the whole engine based on my time constraints. While the engine was out I replaced the oil pan gasket, installed a turner motorsport saftey wired oil pump nut, replaced the oil housing gasket, spark plugs (gapped to what my tuner recommended) Rebuilt the DISA valve with the German Auto Solutions billet rebuild kit and did a few other o rings and gaskets. I did not open the engine besides taking off the valve cover. The car has an RK-Tunes m54 performance flash on it with the burble option, rear o2 delete, sap delete and evap delete. The car has headers and an intake cone filter.
The immediate problem:
After about half the day at the track last weekend we noticed that when i started the car there was quite a bit of smoke that floats up and into the air. It is fairly thick and stays visible for quite awhile as it floats away.
Now I am no newbie to what the colors of exhaust smoke can mean, BUT this smoke is mostly white but does have a slightly blue tint (more white than blue). It has a hard smell to determine becuase it seems to be a mixture of oil and possibly fuel.
There is no signs of oil in the coolant (water and water wetter) and vise versa. Fluid levels are the same as they have always been (last checked 2 days ago now) besides having to add a quart after i drove the car proably 1500 miles if i had to guess which was prior to the day at the track.
As stated before the car smokes ALOT on start up (cold or warm), there is some smoke coming from the exhaust at idle (looked blue-er than on start up) and when accelerating in first and second I can see a small could behind me (assuming that after that I am moving too fast to see an immediate cloud)
CCV system:
Now the CCV system is no longer installed. The previous owner added a cheaper catch can in place of the system. The outlet on the valve cover goes to the catch can and the outher inlet on the catch can is linked to the 2 CCV ports on the intake manifold. When i checked the catch can at the track there was minimal oil in it. The catch can system does NOT have a one way valve in between the intake and the can (I read a few forums that said it should?) Lastly when it comes to the CCV i had to change valve covers because the original one was cracked. The other valve cover I had was not (although it was not new) The over inside of the valve cover that seems to be a baffle before the outlet on the valve cover for the CCV has been removed. (was thinking this may be allowing crank case gasses to pass quicker through the system and into the intake to be burned possibly?)
After doing a bit more research I found that the valve seals seem to be another possible cause to the smoking a bit at idle. SO without doing a compression test (which i planned to do tonight) would it be a fair assumption that the next possible issue would be worn valve seals? (assuming that the excessive smoke on start up is caused by the seals allowing oil to seep into the combustion chamber.)
Thanks in advance to anyone who can shed light on this!
