Default Re: Compression test?

Sounds like you are looking for a problem. Did it make good power on the dyno?? Did it not perform to your expectations?? If you are looking for a problem, leak the motor.... even then, if the numbers you are posting are consistant across the cylinders, you are looking in the wrong place. Even leak testing it's hard to tell because of the variable ring seal at lower pressures. If you have a problem and the pressures are consistant across the cylinders, look somewhere else.

Keep in mind that things move around in a new motor, especially valve seats. I've had a new motor (less than 15 passes) shift a valve seat so bad that you could hear it when you cranked the motor and it only slowed down .02 to .03. If it leaks good, move on.
