Engine oil leaks can occur at the rear main seal and/or intermediate support cover o-ring; a revised seal is available. A careful diagnosis with proper tools is necessary to verify dimensional accuracy of the crankshaft to engine block.Google+

Porsche 911 Problem
Average Mileage: 22,450 mi (20,600 mi - 24,300 mi)
Visitor, 2004 Porsche 911
Car has been in climate controlled garage with 500 miles. A recent porsche inspection as for a battery change and reset notice the real seal leak. Was there a recall for this and was this a known problem. Gee why would this happen and do I need to pull the engine and turbo out or wait and see approach? Porsche says do it on my dime with 22 hrs labor LOL.
The car has only 20,600 miles and never been raced. I have leaks with the rear main seal, and intermediate shaft flange seal. Any ideas why this may be occuring?
