Okay, Xram53...I checked out your photo you attached and I am going to try your idea in the morning.. that is about the only location I haven't been able to check or thought to check it seems i have been everywhere I can on this motor with an inspection mirror and a flashlight and have all but given up and figured we would find out someday when we pull the cab and front clip off to replace..LOL
The only reason we suspect this motor may have been changed is, the original owner owned a wrecking yard and garage and we figure motors may have been pretty plentiful to them and they may have changed the motor out from the original 235??? Not certain of course.. just a hunch. Will keep you posted and thanks for the feeback.
