Replacing timing chain

Be VERY VERY careful and make sure you put the timing cover bolts right back where they came from. There is one bolt hole that's pretty shallow. People have put a bolt too long in that hole before and not liked the consequences. It does not have much room AT ALL between the end of the threads and the outside of the cylinder. Plenty of people have run the wrong bolt in that hole and right into the cylinder and cracked it. That would be a really bad day.
