A Juicy Oil Leak
Hey Everyone
My D3 with a 2.7 has started leaking quite heavily. I suspected the crank seal as I know they're an issue so swapped that for a new genuine one seated correctly. I replaced the oil pump too around a 2 years ago with a genuine one.
Started her up had a quick peak under no more oil leak. A minute or two later it returns, nightmare. I've got a picture of where it's pouring from, any help is greatly appreciated!
For context, it'll take a minute or so before you see the dripping. See the image below, just above the oil pump, I've also checked the Allen Key bolt on the top of the pump which is also dry as a bone.

Plan to take a look at this later today, if anyone has any suggestions before then it would be greatly appreciated!
The V doesn't seem to have a pool of oil either so I don't think its coming from there.

Is that the top of the oil pump ? If yes its probably the pump seal.
Maybe needs a new pump on there. (comes with the seal)
Need to trace it yourself to be sure where it is coming from

That could be from the Oil cooler in the middle of the V, check to see if the rear part is full of Oil you need to use a cable tie or something long enough.
Otherwise as Pete as suggested Oil pump seal, but I have never had one of those leak before.

Just an update in case anyone else is in a similar position. Stripped it down today even further and as above looks to be gasket. New gasket and ANOTHER crank seal on order... I've had a slight oil leak since the rebuild, maybe one or two drips a day, I'm guessing the gasket finally let go? Must have nicked it on installation. Great

Does anyone know a smart way to get the oil pump back on without the plastic insert?

So for anyone that has a similar question this is what did it! Some TIG wire bent holding the pump, many tries, lots of patience and all the swear words in the toolbox.
Cars back together and not an oil leak in sight. The old gasket actually sat lower than the mating face where it was leaking.
