The marks should be there, the gears have not been put on back to front by chance? wash and carefully inspect, they should be there.

The pulleys have not been off since i started the job, but i found some marks barely visible on the intake and one possible on the exhaust that cannot work because the lobes are down and piston would hit the valves. I do not know what has been done on this car before i came by it but i have found a few things that are at least unorthodox. thanks a lot for your help it just seems to be one of those oddballs. Ron
