Hi guys
my engine came out last night and have a few questions ?

before I tear it apart . where do you think all this oil comes from?
Thanks

Common leakers in that top corner of the engine:
- thermostat o-ring
- low oil pressure light switch / source for turbocharger's oil (crush rings)
- crankcase breather gasket and the hose coming off it (transitions to stainless tube)

And below the gray air guide, the upper oil cooler seals.

These are all things that are frequently re-sealed as preventive maintenance when an engine is out.

Eric, I am in a similar boat, for years I have worked on my back on the concrete floor. Next week a new "Direct Lift", 2 post will be installed. Soon afterwards I will be pulling the engine from the 930 with many oil leaks. I am assuming on removing the heads, grinding the valves, possible some porting work and a general overhaul. Hopefully I will not have to open the case.

Keep us posted with your progress, I will chime in as the work progresses.

Had to strike everything I previously typed......

The picture is turned....

Usually oil down the middle back side is caused by an oil leak on the top breather gasket or the tube.
This is made worst by excess foaming in the engine case...
Now this is a likely cause...there are other things that cause this as well....but we don't talk about those things...

if it's oil it's from one of the places listed above but since it's also all over the front of it. It could be grease from your CV joints. I had mine all redone and it slung greas in just the same spots.

good point on the cv's
the top oil breather Thanks

Before you tear it down spray it heavy with gunk or similar stuff, let it soak in for 10-15 minutes and blast it off with a garden hose nozzle. Pressure cleaner is even better. It's pretty wet with oil and looks like it hasn't dried and caked on much yet so most of it will come off easily.
It'll make a mess but now's the time to clean it off.

Looks like it was leaking from the oil switch area for a while. It's wet with motor oil all around there and collected a lot of dust and dirt making oil mud. One good thing is the aluminum is protected and doesn't corrode from water under all that gook and will look nice once it's cleaned off.

What do you guys go with the hose coming off breather (transitions to stainless) .mine is real lose and a new one is 300$.
Thanks

cut off the crimp securing the hose, discard it and the dried up hose. Replace the hose with oil-resistant hose and a pair of stainless clamps.

Just did mine. Leaked in exactly the same spot. The original oil line is aluminum with a rubber transition piece crimped on the engine end. Looks like the PO removed the original part (probably cause after 25 years, it was toast) and cut off the crimped end. This seems to be the common repair approach. Unfortunately he didn't use an oil resistant replacement hose, so it rotted and leaked. I pulled the engine and replaced the hose and put two clamps on it. Cost. $1 worth of hose and two clamps.
