I am replacing head gasket on my 15 horse Johnson but in a recent post, F_R mentioned 'crankcase pressure' and I have always been curious of the procedure to check this (and what is the acceptable range). I was tempted to replace the exhaust gasket too and wondered what the procedure is and how does one gauge if, in fact, it needs to be replaced?
