[Katrina/10]

I heard that timing gear could be a problem, so I ordered a steel gear set, then took the cover off. Guess what, the fiber gear was perfect! So I took the cam out to change it anyway, hoping that might help with something. I found the roller lifters had worn grooves in the the cam, so ordered another cam. Finally got everything put back together, and it still rattles. After going through the entire valve train, it must be something piston related.
