excessive 340 crankcase pressure

well then live with what you get and quit whining about the dipstick acting like a blow-off valve.
and good thing it does, cuz if it didn't, maybe the rear main seal would blow out, or worse,the rear cam plug. 5psi crankcase pressure on a 2" plug comes to almost 16 pounds of force; hope you glued that plug in...... That hose will be really really cheap compared to replacing that camplug...... a quality piece of heater hose has lasted me for nearly two decades It mightabin $1.25 a foot back in '99
'Course; file-fit Plasma Moly second rings do a pretty good job of reducing the blow-by to a minimal amount.
