On a 1,200 mile road trip I used 4 litres of oil, it was that bad! The back of my car was covered in oil and I left palm sized patches of oil on the ground whenever I stopped. It became intolerable in a engine otherwise dry after a full OPC engine rebuild.

I first found a leak when I dropped the engine in late 2015. At that time it was definitely the nose bearing area as the OPC had covered the area in RTV which had ballooned with escaping oil (a separate discussion I'm having with them as to why I had RTV there on my engine after a full rebuild)

I took the RTV off and installed a Tom Amon collar. I didn't think to check the Intermediate shaft seal as it was hidden under the AC support piece.

My assumption with the continuing leak was that the Tom Amon collar wasn't working. Now that I have full access I suspect that the Intermediate shaft cover is a bigger leaker, but likely not the only thing.

My plan is to replace the O ring and seal the outside of the IS cover. I will also add a layer of sealant around the Tom Amon collar as I don't want to mess with the JB Weld to get the collar off. I will then refit enough items to allow the engine to run and see what comes out.

I can tolerate a small leak there, if faced with having to split the case as an alternative. I've just ordered equipment to allow a rebuild of my other 964 with 147,000 miles and that's the bigger priority.
