Okay. I bought new cam shaft pulleys and Gonna install them this week. The oil seals are new and it just had a complete head job including new valves and lifters. On the end of the camshaft where the pulley actually mounts there is a shallow groove about 1/4 inch back from the end and I thought that was for another o-ring but I was mistaken. Hopefully this works; think I might replace the oils seals again just for good measure.
