He rebuilt the engine and then said the leak was not his problem, sounds like attorney time.

These cars of ours can and will leak from lots of places, maybe 10 or 15 different places. Not to state the obvious, but you need to find out where it's leaking from. First thing I'd check is your oil level in the oil reservoir . Could be as simple as an overfill after rebuild. Lots of leaky spots will put oil on the bottom of the case.

Post up some pictures.

I had a similar issue when the shop apprentice set the timing wrong causing detonation blowing out the base gaskets and destroying many rings. Fortunately I'm in really good terms with the shop owner who let me redo my engine with advice from the chief mechanic. I would sue the shop owner but negotiate for shop half shop time you pick up the parts. Anyone can drop a 930 motor in 30minutes. It can be stripped in a couple of hours. Those quoted prices a bit high imho.

Oh man that sucks. I can't quite identify where the leak is on the engine. If it is from the case parting line there is no gasket there. Only a sealant is used on the case parting line.

Uwon a member here had a similar problem and if my eyes are right it appears to be from the same spot, though yours appears worse. Here is a thread he did in the subject.

New Build Oil Leak Grrrr.....

If I can do anything to help out let me know.

When you had your engine rebuilt did they split the case,or was it a top end rebuild.

Wow that is one bad ass looking car.. sorry to hear about your oil leak woes. Like others have said- first you have to find the leak. What kind of jack ass rebuilder tells you a leak on a brand new build is your fault? That stinks.

IF it is actually leaking from where the chain housing seals to the case, maybe you could pop the chain box cover off and really clean the dickens out of where that gasket mates in between the box and the case and cover it up with some JB weld (or loctite hysol.. slightly more Porsche kosher because you can't get it at Pep Boys?) and seal it from the inside.

But I looks like you already tried sealing it from the outside so maybe that' not the source of the leak.. maybe the leak is nearby but you see it there because its the lowest point on the engine in that vicinity. Keep poking around and let us know what you find.. hopefully its something trivial! could be any number of things in that area.. chain tensioner oil lines, cam spraybar feed fitting, oil pressure sender, ims shaft cover plate.. etc. Heck maybe its leaking past the threads on those nuts there.. they don't look like nylocks.

Anyone who uses that much goop on a rebuild shouldn't be rebuilding anything...

Did you have them replace the Nose bearing or #8? I did a split case rebuild on my engine about a year ago and sourced a Nose bearing from an aftermarket supplier (BAD IDEAD!!!) My engine left some drips the first time it ran. I ended up taking the engine back apart and replacing the nose bearing with a Porsche part and all is well. I did measure the seat where the gasket fits into the bearing and there was a very noticeable difference between the aftermarket and Porsche. Wish I had spent the extra $200 at the time.

I wanted to avoid another "rebuild" and found some information on a "fix" before going back in. Here is a link to one of the solutions I was considering. I also found a guy Henry Schmidt at Supertech Performance 760-728-3062 makes a kit. If this happens to be where your leak is coming from.

Good Luck!!

There is no replacement for correct assembly of the case with regard to nose bearing. My engine is an example of this. Leaks and will not correct without respliting the case. Tried everything.

I'm having trouble working out where that leak is coming from. It would be worth identifying that first - especially before an engine out job - or else same problem may surface.
Clean that gunk off and spend some time watching it. If it is the chain case, a relatively easy fix and engine can stay in place. But you will need to work out why it is leaking where it is. You can check the chain case cover is true/straight, if that is the place. They normally can seal with just a gasket and no gunk on the gasket. You could also try your way around the nuts on the housing and make sure they nipped them all down - you never know.
Let us know what you find.
