Hi guys,
this has probably been covered before, but a search of the forums did not give me the answers I needed.
I have a 98 VT V6. I noticed the other day that my car missfired a couple of time during light acceleration
it doesn't happen all the time only has happened a couple of times, (was thinking maybe a dirty injector)
but today I decided to do an oil change and noticed inside the right tappet cover was very milky. I cleaned as much out as possible, but eventually decided to remove the tappet cover, it was completely full of milky oil, But none on the rockers or valve springs. if I'd scraped it out probably would have been about 1/2 a cup. any way I drained the oil out of the sump ( it was NOT milky at all, and no signs of water on dipstick, and no oil seems to be in the radiator) I didn't remove the left hand tappet cover (as it was dark) replaced oil filter (no sign of water in old oil filter) and refilled with new engine oil.
I am thinking the valley cover gasket maybe allowing water into tappet cover, is this possible are there water galleries in valley cover that could allow water into tappet cover.
I am finding it hard to believe it's the head gasket, although that would explain a missfire. but running the engine with radiator cap off shows no signs of bubbles or exhaust fumes.
can any one tell me why the oil is only milky in the tappet cover and not entire engine.
I did noticed the tappet cover gaskets have been leaking a bit of oil, I am hoping the problem is only caused by a leaking tappet cover gasket, from last time I pressure cleaned the engine.
I guess a leaking valley cover gasket could also cause a missfire, so at worst hopefully this is all it is.
the car did overheat about 4 months ago, although the guage did not reach the red, it was a few bars off. but the temp warning light and chime came on, but went off a few seconds later. and guage returned to normal, radiator level was down about 1.5 - 2 litres.
