Rear Main Seal


Vehicle Information: Year: 1999; Engine (type, size, modifications): 2.5; Total Mileage: 40000; Transmission: Manual;

I noticed your answer in October Panorama. It seems like Porsche or experience has refined the fix for the RMS problem, or at least recognized its existence. I have a 99 Boxster that has had RMS replaced at 27000 by previous owner. The car now has 40K miles, but is in otherwise great condition. Recently it has started to leak oil and has been diagnosed as RMS problem. The leak is very slight, and does not cause any problems other than a few spots on the garage floor. Can I just put up with the leak, or by ignoring the problem, will it eventually destroy the engine by displacing the crankshaft? The second question follows the result of the 9699/1 test if I go that far (I assume that the engine has to be removed to perform the test). If the test fails, is it worthwhile to replace with a new engine, considering that the value of the car is probably not much more than 20K, or do I run the car until the crankshaft/seal fail catastrophically? Any suggestions would be greatly appreciated.
