motor was out and rebuilt. Reinstalled. Everything working. Sounded like it needed the valves adjusted. Rattling a lot. Pulled a valve cover. Went to adjust them, but I can’t. Most of the pushrods are loose and I have no room on the adjusting screw to tighten them up. The problem had been getting progressively worse and the motor is just not making a lot of power. I’ve pulled the intake. Everything looks new and good. Cam doesn’t look worn down. Tappets all look clean and new. I’m not a motor guy and the guy that built it is an engine genius but was not that familiar with poly’s. Did we miss something? I have to think this is some kind of simple problem. He is coming over to look at it. He suspects the cam lobes are softer than the tappets and may have just ground them down during a poor break-in procedure by me. The motor has about 400 miles on it and one oil change. There is lots of wisdom on this board and I am hoping to tap into some it!
