After I do a boosted run and come back to idle (say at a stoplight), the car smokes like crazy. I have done about 2000 boosted miles, and car has consumed about 3 quarts of 15W40 in that period, where earlier I needed to put in a quart every 3000 miles.
These things are out of the question:
1) Boost getting into crankcase and rings not sealing - Because I am running THIS
valve in between a cheap autozone PCV and the intake manifold. The other vent on the valve cover is plumbed pre-compressor.
2) Leaking compressor seal - Because no oil in the hotside or coldside pipes.
3) Leaking turbine seal - Because no oil leaking out of CHRA
4) Low compression - Did a compression check, it came out 181/180/180/181.
Could my PLUGS
be telling me something?
What do you guys suggest?
