maybe it's piston ring / ringland damage?

as Dub 7 says, pistons, ring damage,
I had the same Problem, oil coming blewing out of the dumpvalve,
3th piston crack,

x3 pistons, ring damage,

as above - usually indicates damage to the engine rather than turbo.

Craigs done the same. excess oil from the crankcase breather on the rocker cover and pissing out the dump valve. also getting past the oil cap. turned out to be piston no 2 had broken a chunk between ring no 1 and 2. take the cap off and check for pressure using your hand and see if its blowing quite harsh. failing that compression test will reveal all. compare the ratios as they should all be around the same on a healthy engine but if you find a low one compared to the rest then theres your problem

Hi

The car is not smoking at all and the plug is fine as well.It could be the pcv valve?
Thanks.

find out by unplugging it from the manifold and letting it vent to atmos, ensure you block the take-off from the mani to prevent a leak

Hi

Can't get clearly what you mean by unplugging it from the manifold.

Thanks

just pull the pipe of from the pcv valve to the inlet manifold & block off the inlet manifold side so you dont get a vacuum leak.
also you should do a compression test to check ring/ringland damage

looks like piston/ ring damage unfortunately mate, my friend experienced the same!

^^^^^^ by the look of it though he doesnt believe this

compression test. 5 minute job and will tell you straight away if its f****d or not. saves pissing about with pvc valves etc.if all comes out ok then start with pvc etc
