Hey guys. I did a compression test on my block and #2-#6 were all @ 145-155psi. #1 was @ 110psi. I then did a leak down test and #1-#6 all held pressure with almost no loss (I think it was less that 5%). There wasn't any air escaping through the exhaust or intake manifold or the PCV system. My teacher suggested my intake valves weren't opening up all the way. I was wondering if it could be anything else, before I start measuring valve cleareance. The car runs great though, on 10lbs.
