I'm hoping people on here may be able to help me, after my turbo blew oil through the compressor seals for the third time i have decided to stop blaming the turbo and am now looking into the engine.
To that end i have just carried out a compression test on a hot engine with the following results:
Cylinder 1 2 3 4
Compression(psi) 141 133 142 141
The problem is i can't find a definitive answer on whether these are any good, they seem a bit low which would explain why i only get oil as the boost pressure builds up. Also the engine is fitted with a HKS 1.2mm head gasket (not sure if this affects the results).
I have also tried checking that the oil return from the turbo is clear by pouring oil down it which hasn't backed up so i believe it is clear.
I'm starting to clutch at straws now as i'm coming to the end of the project and this is really frustrating.
Thanks in advance for any help anyone can offer.
