On my stock runner I installed the engnbldr timing set with oil pump and everything was red locktited and tourqed to toyota factory manuel specs. After about 5000 miles the trucke stoped running north of denver miles from anything. So far I pulled the valve cover off and looking down with a flash light I can see that at least 3 teeth on the crank gear are broken and shavings are in the front of the valve cover. son of a bitch! anyway I'm not so happy with the quality so far. does anybody know if these are warranted, If so is it worth it? From what I have read on this forum everybody loves this companies product. has anybody had a similar experience like this yet? I can't think of why this could happen exept for a defective gear.
