I am new to this sight and new to diesel trucks as well. I have been looking to buy a 7.3 powerstroke for awhile now and found one that I think I want. It is a 1999 F250 with 68000 miles on it, but has a couple problems. One is that the flywheel is missing a couple teeth. My question is how big of a problem is this going to be and how big of a hassle is it going to be to fix if need be. It also says that the ebpv valve leaks a small. Doesn't sound like to big of a deal but like I said I'm new to this stuff.
