I got an 89 T2 and had a aftermarket turbo on it.So that turbo recently went and put a stock s5 turbo on.after installing im getting a decent leak on the adapter between the manifold and the turbo.I checked every bolt and its all tight.i never had a leak there with the other turbo.I had someone tell me i have too much oil pressure and sucks for me the gauge doesnt work.Anyone no why it would be leaking from there.

 

Are you absolutely sure the oil is leaking from between the manifold and turbo? Or is it perhaps dripping down from the oil feed flange at the top of the center section?

If it is leaking from between the manifold and turbo then there is an internal oil leak in the turbo. This would be accompanied by some exhaust smoke.

If it is leaking from the feed flange, you probably just need a new gasket or to snug down the bolts.

No, it is not high oil pressure. Whoever suggested that is stupid.

 

ok yea feeling its the turbo beacuse i drove it and it bogs alot turbo does also have some play.My neighbor told me the oil seals in the turbo are no good from his perspective so im guessing he was right.
