Plus if you have one higher that can be a problem but not if ones lower than the other 3

have never cracked the engine open. If it was too low the mechanic would have informed me. of course it would be higher with new rings...

hot or cold motor luke?

WOT?

all spark plugs removed?

gauge calibrated well?

nah ...im just shit stirring luke,u know me....

if u crank long enough,the extra fuel can help seal the rings a little,so i believe
the main thing is a decent reading above minimum & good consistency across all 4.
