leakdown/compression

So my JDM B18C is on its way from Hmotorsonline. The guy there said my compression/leakdown was 225 for each cylinder and the motor had 38,000 miles on it.

Is 225 good/average? TIA

yeah those #'s look fine, plus all 4 cylinders having the same #/consistency is a good thing.

Leakdown is measure in percentage and therefore can't be greater then 100% (which would be very bad BTW). Don't look for peak numbers in a compression test, look for consistency.
