SR20DET burns oils sometimes when stopping

[SRpetey]

Ive been having this problem for about 3 months now. The car starts fine and runs like it always has. Theres no smoke at start up or when driving. The only time that it smokes is when i come to a complete stop when the car is already warm up and have been driving for more than 10 min.

Im usually at a stop light for about a 45 seconds and alot of smoke starts to come out. When i start driving the smoke goes away and it doesnt come back in the next stops i do. It doesnt do it everyday either.

I have a SR20DET with bolt-ons and a oil cooler.

How do I check this or figuere out whats causing this?

I know oil rings, valve seals, PCV, or turbo can cause blue smoke but how do I find out whats causing mine to smoke?

turbo seals... guaranteed

it's happened to me 3 times on both SRs and KA-Ts. changing the turbo fixed it each time.

New turbo time. Also a very small chance of valve seals, but more then likely turbo.

I did one and it was around 88% on all four with a cold engine.

Thats what I thought it was and also was hoping it would be since its just a t25.

I dont think it will be the valve seals or else it will smoke more often than it does.

As in 12% leakage? thats a little on the high side...generally you want less than ten.

Turbo seals. My old T25 use to do this crap randomly. It would be fine for a few days, then suddenly decide at a random stop light to start smoking up.

Yup Turbo Change it

it was on a completely cold engine. im pretty sure if its warm up ill leak less plus the engine is old anyways

Whether you have full blown acne or just the occasional pimple you know that it is uncomfortable, embarrassing, and something that most want to prevent. To stop acne use tea tree oil face wash and cream, and other tea tree oil products. Although there are many different types of acne treatments on the market, many very expensive and sometimes damaging acne prevention treatments, the use of tea tree oil face wash and cream to stop pimples is easier and relatively safer.
