i have 94 ls w/ a drag gen 3 kit motor only has 60k on it. it smokes sometime...pretty bad when idling usually after a boost run...is it possible that it could have a bad seals or a minute leak that is dumping oil on either side of it. i noticed when i swapped out the old motor for this one there was some oil in the pipe going to the intercooler and some on the filter side of it....there is only about 4 weeks of use on this.....at 10psi...it doesn't blow huge clouds at full boost like it did on the other motor which lost 100psi compression in the #1/2 cylinders
