My buddy came to me this afternoon with a question about his 06 GT. He thinks he might possibly have a bent exhaust valve. I've never heard and engine with a bent exhaust valve and after I listening to his, it sound pretty normal:shrug:. He had mention something about it backfiring when he is shifting from 1st to 2nd or 2nd to 3rd. I have no clue what to look for or even know how an engine with a bent valve acts or sounds like. Anyone?
