B20 oil leak fix?? - Page 2

Thought I would provide some pictures. Do not see any oil leaking down on the block.

In the second picture: You can see drips down the side of the sump - it doesn't look to me like that bit came from the rear crankshaft seal.

I think your first step is to clean as much of the engine and gearbox as possible to help identify the source of the leak(s)

Yes, lots of degreaser and a fierce hose and then see what you find after a few miles.

I agree with Army and Derek...clean, run a few miles, inspect for source...

Good Hunting!

Will do. Project for today.

Here is the pic of the underside cleaned. Engine is clean. We will see where the oil comes from. I still suspect the rear main. Could the gearbox leak in the front? The oil is similar.

The gearbox front flange for the input shaft, which also holds the front bearing in, is attached using 3 bolts. As well as a spring washer they should also have a rubber O ring on each. #380381. If these are missing oil will leak out from here. O ring sits against the flange, then the spring washer, then held by the bolt. There is probably a small recess for the O ring so it remains slightly proud before being squashed by the spring washer.
