There are two oil lines to the turbo
one line is a pressure line that delivers engine oil at pump pressure to the turbo
the other is a low pressure line that drains the oil back to the sump
determine which line is leaking and replace or fix and replace the gaskets or "O" rings

Hello, i have recently purchase an 85 vanagon westfalia, with a 93 turbo diesel toyota engine, and it does not fit, so some modifications were made, such as the matress on top of the engine on the back had to be cut ,, its like a big square, its not that bad, i can still put a thin matress on top of that square and its just not as soft,,, but my real problem is that i still have the same 4 gear vw transmition, so i am now in the quest of a vw golf 5 gear transmition that would fit , my other option was a subaru transmition ,, but it was kind of expensive, if anyone reading this know of other options please let me know ,, also i was told that i have to change the radiator & fan for a bigger one and also see a way to install some sort of fan right next to the engine on the back,, since diesel engines run hotter,, i am not really a gear head ,, dont know much about this things.... any comments or recommendations?

Your description sounds like a waste-gate problem.
These are intended to prevent overpressure from the turbo and yours might be faulty.
The oil leaks may not be related to the other problem - Jeez, would love to own some vehicle that never leaks oil from somewhere.

this tells me that the injector timing is off just a bit or you may have a weak injector all together.

MY 2001 7.3 was leaking the same way. The dealer said the o'rings under the pedestal were leaking. I had the dealer replace the o'rings. By the time I got home, it was leaking again. Called the service department and told the manager,and they put on a new pedestal and o'rings. They only charged me half price for the pedestal and no labor. That did stop the leaks.
