Looking to fix the 4e leaking seals but repairer says they will leak again.
I am wondering can pressure through valves seals get into the block and push out the block seals?
Seal Symptoms are -
Exhaust back pressure seems to be the cause of oil squirting out of the top breather.
Intermittant idle revs drop now think this may be due to oil dripping on spark plug through seals.
Compression test last year was 160 dry on all cylinders but the wet comp. test showed 200 195 180 170
