ok this is not for me but for my friend. he has a 2nd gen. eagle talon with a 1st gen block and 2nd gen head and a whole bunch of other shit done to his car. anyway he came to my house last night wanting to look at my engine and haynes manuals. well he came to the conclusion that his crankshaft pulley is bent? how can that happen and what kind of repairs would he be looking at?
