The Back Story: I was driving 55mph when suddenly a loud thump was felt and heard. engine stopped. I pulled over and attempted to start. No go, Got it home checked a number of things, then pulled the valves covers and noticed the valves were not moving. Not good, fast forward 9 months. I finally tore apart the front cover and found the camshaft bolt broken, the timing chain was still on the cam gear. and on the crank shaft. I have a 2000 Ford 4.0 OHV(thank God). my truck only has 148k with 2 new heads
1. Can I drill out the bolt that's in the camshaft, left or right hand threads?
2. Its a stock motor, do I have enough clearance between the valves and the pistons? I've been told I do by a friend who did a google search for me. But I could not find anything.
Thanks Pctc
