Carlisle Chrysler Nationals Carlisle, PA

The rear main seal leak on the Dart gas returned. I am beyond frustrated. I have had this engine out 3 times already. I put the Superformance seal in and it worked great for several months but now the leak has returned and I had to have the Dart flatbeded home. I am currently in Larry's truck heading to Carlisle, I'll have fun but it's just not the same without your car Larry's brother Bob thinks it could be the fact that the Dart runs at 70 PSI at highway speeds and the high pressure coupled with the temperature caused the main seal to fail. He thinks I should go with a stock pump, what do you guys think?
