I have a TR4A that has the typical oil leak. I read that a bad PVC valve can
cause that engine gas can force oil out of the seals. I replaced the PVC valve
and hoses. The problem is the engine build up so much pressure that it blew
oil out of the PVC valve seal. The car is now in the shop and I am being told
that the engine will need to be rebuild because there is too much blow by in
the rings. I trust the mechanic but it seems to me that if that much gas was
getting past the rings that the car would be smoking like mad. The car only
seems to smoke intermittedly as though only when it vents engine gas. I did
also replace the breather oil cap with a non breather type (the correct type
for TR4A closed system) with the breather cap on when driving the car you
would get out smelling like oily exhaust. The engine runs very strong in every
other way. Anyone have any suggestions.
