Porsche 911 Problem Report
Porsche 911 Rear Main Seal/Intermediate Support Cover O-ring may Leak Oil
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.
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. - Visitor
