Anyone ever shredded a timing belt. I just did after a complete rebuild with driving 1500 miles after putting it back together the timing belt shredded to pieces. I’m looking for pointers as I really timed the engine with another belt it turns over but won’t start I also have a 0.020 spacer shim at the head gasket. Should I just dismantle and start from scratch again or is anyone been here before. Please help
