Iam in Hot Springs Ar......with a a badly missing 460....My scanner shows nothing .....Iam looking for recommendations for a shop to scan my engine beside Riser ford....I cannot leave my MH a few days...
If you have access to an infrared thermometer, shoot the exhaust manifolds at the head. The cold reading will tell you which cylinder is bad. I have seen 460's break rocker arms or put the pushrods through them.
If you find a could cylinder, pull the valve cover and take a look.
