I just bought a ep71 with a 4efte in it, there seems to be some oil coming thru the stock plumb back blow off valve. Its definately coming from the CT9 and a mate told me that the oil seals need replacing.
What does it cost to get the seals replaced and would i be better off buying a new turbo instead?
Its only a very small amount and doesnt blow smoke(it has once after a hard test drive for a mate), so will these damage my engine at all as the seals get worse or will it just dump oil into the exhaust and limit the turbos efficiency.
