I have done a lot of research and know that b20s have a valve problem. (they tighten over time, and honda said you don't have to check them til 105k by then it's too late). I bought the motor with 120k on it and was told it has low compression. I rebuild the whole thing. #3 valve was crack thus making the bad compression numbers.

Sorry, I adjusted the valves 1st before putting the MOTOR in the car, not before the cams in the motor. Yeah that would make it difficult to adjust the lash with no cams.
