howait everyone. was kinda wondering if $500 is worth it for this truck. My mailman owns the truck and just recent, the timing chain must've skipped because he has bent valves. I personally did not inspect the engine, but a mechanic friend of his did. So, bent valve means new valves and seats, head work....etc... Would anyone know how bad the piston could get? I guess worst case scenario is a crack piston? The truck has no rust and the a/c blows real cold. Part I don't understand is its only got 50K miles. Let me know your thoughts. Alohaz.
