I hate this job. Follow instructions, damn pin falls out. Took an hour to get it compressed to get it out. It jumped 4 or 5 teeth, so off comes the valve cover--started hard as dummy me missed a bolt. What sucks is it all seems lined up, you snap the tensioner and find out different. Cams perfect ,but one tooth on the crank is easy to do. Is it better to have the tension tight by the tensioner, or loose when you release it?
