Even if the crankcase was pressurised, it would be from the combustion chamber pressure leaking past the rings. So the combustion chamber pressure will always be higher than the crank case pressure. The oil would have been blown through the PCV into the intake manifold and then into the combustion chamber. That's why replacing the PCV valve fixed the problem. The valve was sticking open. With the new valve, it stays closed even with the higher pressure and so you didn't have your oil vapour being pushed into the intake manifold.

ok, update on motor!!! havnt got a compression test as yet but there is now drops of oil spiting out the motor when u take the oil cap off :(

this is bad so i asume i should get the head pulled off and check the condition of the bores and rings?

also i checked out my oil catch can and its not fitted right, its been fitted from where u usually put the oil breather not anywhere near the pcv valve.

cheers Jared

oil drops spit out of my engine when i take the oil cap off too!!!!

taking the oil cap off is NOT a terribly useful diagnostic proceedure.

take it to a actual mechanic, as we have all suggested you do for the last 40 posts...

rofl.
of course oil is going to spit out.
see how the cam is sitting just bellow the oil filler hole. when the engine is running that is spinning very fast. there's a good chance its going to flick some oil up.
why do you assume this is bad? you do realise that there is supposed to be oil up in the head and it doesn't just get there via bad seals/rings?
at this point it really does look to be an issue with the PCV system. is the catch can picking up much oil?

Hey mate, I noticed you're on the central coast, same as me.
If you want to pm me, I can give you names of people worth seeing on the coast, and people to avoid. Plenty of the latter around here.

What you may want to do in future is, for major work (e.g. engine work) and issues which don't require you to be towed, take the car to Hanny's Performance in Smithfield (Sydney)

Was a bit of a drive for me, but well worth it. If you have a honda and can get there, I'd get there.

P.S. didn't realise i was raising the dead, shoulda pmed him. my bad.
