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?
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.
