Another oil leak - any advice?

[c3nturi0n]

I’d suggest to check seals around oil pump.

I recently replaced PAS pump and as part of the job we replaced dozen or so seals... some were done preventatively while other ls were showing ‘wet’ signs.

Having had a chance to sit down and take a really good look at the pics, the oil on the subframe seems to be too far back for the turbo oil lines which are forward of the drive shafts. I can't think of anything oil-related in that area as all of the engine is forward of the driveshafts. I suppose that it could be brake fluid from an overflowed reservoir but from experience (yes, I changed some pads without checking the fluid level ) it doesn't drain out there.
I'll slide under my car tomorrow and see if anything gives me a clue.

Ian, Jim, first off, thanks to you guys for your help. I don't know what this forum would do without you.

That said, I'd like to declare myself a huge turd. I feel about ten years older, and about $10K richer. I entirely forgot about the brake fluid; and check out these pics:

Although I never looked behind the brake cylinder before doing the job, I'm pretty sure it did NOT look like this:

Level looks pretty full as well.

The floor in the overnight garage was also dry, so whatever leaked, must have stopped.

I dumped about 5L of water on and around the brake cylinder, hoping it'll wash off some of the brake fluid residue and follow the same leakage path.

You've confirmed a thought I had late last night.

I suppose that it could be brake fluid from an overflowed reservoir but from experience (yes, I changed some pads without checking the fluid level ) it doesn't drain out there.

Then later on I thought 'Hang on, the plenem drains are there, why didn't my fluid leak there? Ah, because back then the drains were blocked with leaves and sh*t you idiot".
