In the 930/911 pulling the motor is not difficult.

If could determine exact location of seepage machine shop could certainly solve problem. The motor seems to be going into service. I would say no on the leave motor in, pull turbo, fix cam tower oil seepage issue. Can you pull motor, (builder)rebuild it it if necessary. You will probably be in top end rebuild territory to fix such oil leak.

1989 930 is tops !

Goodluck.

Mine has the same leak. It was coming from between the cam towers and the cylinder heads. What really sucked was the leak dripped right on the header so every minute or so a huge puff of smoke would pour out from under the car. It was starting to get really annoying!

I ended up pulling my motor and will be doing a top end rebuild to include the heads, rings, rod bolts and misc re-plating and powder coating.

I decided not to split the case after removing the #5 rod and the bearing looked brand new.

Mind you, I had to remove one of my heads anyway to repair a bad attempt at a thread repair. So I figured I might as well freshen the top end. If I didn't have to remove the head I would have probably left everything as it were.

Are you sure that it is not just leaking from the lower valve cover? It's an easy fix and I'd give it a try before pulling the engine out. I'd get a set of silicon gaskets and make sure that the valve cover sealing surface is flat. Clean all of the surfaces with brake cleaner and then put it back together.

Look at your rockers and make sure the rocker shafts are properly placed as they are oil seals. I have a hard time seeing mating surfaces , heads to tower as leaks if they were properly sealed.
