 I believe that the lightweight crankshaft pulleys add to the problem of the oil pump failures. The lightweight pulleys change the harmonics on the end of the crankshaft. They set-up a vibration that can't be dampened out. Since the oil pump is driven off of the front end of the crankshaft. The vibration goes into the oil pump. breaking the gears in it. Dodge Hemi's have the same set-up almost. And there have been quite afew failures of the oil pump with the light weight pulleys on them too.
