I have been dealing with a smoking issue for a little while now. It is more of an annoyance than a real problem. I have found it to happen under two scenarios:

-On a cold start, if I let it idle for about 5 mins it will start to smoke until I start to drive
-On a cold start, if I do any heavy acceleration within the first 5-10 mins it will smoke a little after the acceleration and stop after the car warms up.

When it smokes, I can see a little smoke coming out of the breather so it is not coming from the turbo seals.

I have a built motor with about 30,000 miles on it. Compression and power are good. I am not loosing oil or coolant.

My guess I just have normal ring/cylinder wear and oil gets past the rings when the pistons are cold. I don't think it is the valve seals as it does not smoke immediately upon startup. If I start driving right after startup and don't get under heavy load unit it is warm, I will not get any smoke.

Any ideas?

Thanks.

 

What type of pcv set up do you have? That probably the problem. You can't have the stock pcv set up or the car will smoke.

 

Stock PCV is gone. I am using a catch can using both ports on the back of the block (one in and one return) with a breather on top of the can. The valve cover just has a breather filter.
