Found another thread on the same topic. All good to go.How fast should the pressure/vacuum numbers fall when doing a crankcase pressure/vacuum test? I know they shouldn't fall at all, but when I pump the crankcase up to 10PSI, it falls to about 8PSI within one minute. Same rate of change with the vacuum test. Is this an acceptable rate of change? Thanks.
