hey i just got my car back its a b16a2 with a greddy 18g turbo it has je low comp pistons just put in cause i recently fried the rings and decided to put pistons in also i know have the car back and running but it is smoking again but i did a comp test and its fine im thinkin maybe the valve seals or somethin in the head if anyine can help that would be great thanx

try doing a leak down test. this test is better for checking rings. the cyl. wall may have been over honed.

how many miles on the rebuild?

may need a breakin
