rocker cover

Repair engine oil leak on front cylinder between rocker box and cylinder head. The factory seal failed during a dyno run at Harley Haven back in 1999. The repair lasted until now (2009) but left the edge of the gasket protruding from the seam. Recently that protruding edge broke and the leak began.
