Drivetrain Bad luck after M7 2%!
was the M7 Crank pulley heated to 475 degrees in an oven prior to the install? the piece is an interference fit so it needs to be expanded by heat to get it pressed in far enough on the crank shaft.

Well M7 is sending me a new 2% pulley for me for my suffering. I do beilieve that the install was the whole problem. It looks like the crank bolt was put on with way too much torque and stripped the crank case. Hopefully when this is all done I will get to enjoy my car gain with the new M7 pulley. I guess even if products are good, the install can still ***** it up.

Correct me if I'm wrong but how hard is it to strip the threads in the crank. It is my understanding that these are made of some pretty strong metal.
