Yes, I installed the pilot bearing. I am going to go over this with a fine tooth comb as they say. I will take my time putting it back together after what ever is wrong is found and fixed. The machine shop said check for a loose or bent windage tray first. If I don't find anything on the bottom end that is obvious then I will tear it down to the short block and take it to the machine shop for them to take it down the rest of the way. I also will make sure I have the intake thing taken care of. EB
