If oil leaks from the oil cooler on top of the engine, the rear crankcase bolts, or from the intermediate shaft flange seal, or the intermediate shaft flange bolts, then engine oil will show up in the same place it does for when the rear main seal leaks. The exact source cannot be determined until the transmission and flywheel are removed. This is why there is a new repair procedure.
The good news is that there is a new seal that just came out with the 997/987. This is the 3rd version seal. It is the same size as the 996/986 seal so now that is the replacement for the prior models. The bad news is that there are 2 confirmed leaky 997s with this seal, and a 996 owner from Liverpool with this new seal.
If your crankshaft is not in specs then a replacement seal, if it is the RMS, will most likely leak again. We have a local Boxster owner and the 2nd generation seal was replaced 5 times, then Porsche gave up and put in a rebuilt engine - which is another story. The 996 owner I mentioned had 6 replacement seals. What month and year was your car made?
Monitor the oil and just drive it. You do not have a gusher.
