seem to have way too much crank case pressure , ive replaced the cam cover gasket several times in the last month, as it keeps pi**ing out oil,
the hose on the pipe that runs parralel to the dip stick has split pi**ing oil all over the manifold, i have cleaned the filter in the cam cover out but im considering removing it all together to reduce the pressure, obvioulsy i will clean all the hoses out and check for blockages, but is there anything else i should consider??

blow by/head gasket are my 2 main fears at the moment not because they are especially difficult but because ive just spent a fair bit getting through the mot, and i need my car every day.

any way nuff of that moaning, i will do a comp test but on a very recent one it got 200 psi across all pots no water/oil contamination.

if im still getting good comp were do i look next ?

just had a thought, dont think its blow by as i would expect the weakest link at the crank end from excess pressure would be the sump gasket , not a hose at the top of the engine , no leak from sump.........yet

i suspect the cam case breather filter .

hmmm hadent considered the gasket it self maybe substandard (halfrauds) any way ordered all the bits from auto vaux so will do a proper job on it.
I used 2 Halfrauds gaskets, both blew out and leaked. I cleaned all the faces and fitted a GM one and smeared it with sealant first and all was well.

it hasent blown the gasket out, it just leaks all the time from the moment it was fitted.

the single cam cover breather hose (8v) vents to atmosphere but ill make sure its not blocked.

like i say i havent spent anytime looking at it yet due to concentrating on my mot , and im just getting some ideas so ruling nothing out.
