I have a new chain and both sprockets, and finally have the cam to crank timing set properly. I must have turned the engine over by hand 50 times. When I went to put on the timing cover, I noticed wear marks on the teeth of the crank gear. I had to look closer to believe it. It's hard to get a good picture, but I've attached two. The top sprocket looks fine and so does the chain. Normally there would be more oil in there, but the chain is not dry and I didn't expect to see wear already. Is this normal, or should I give Moss a call -or maybe try another crank sprocket?
