Hi all,
Very disturbed to find an air filter full of oil after a drive. As a diagnostic I disconnected the PCV line and installed a breather (so breathers on both rocker covers, vent at rear of engine open with small filter) and after a short drive there's oil everywhere. I removed the filter from the small breather at the back in case it was blocked, so now there's NO vacuum at all and the engine is still spilling it's guts all over the engine bay. So to me this says there's excessive pressure in the crank-case? Which would mean what - a blown ring? Step one to diagnose is a compression test, yes? So tired of problems with this car.....
NB, only spilling out of the even bank, and out of the breather at the back which has a hose attached, about as long as the tranny dipstick. One bank might mean a blocked return gallery perhaps?
