But even with this new dist same problem. I remember putting in the timing chain and cam and had set it on zero and had two other mechanics double check me. And the balancer.only went on one way.
Sometimes the balancer fails where the outside turns and comes out of alignment. If you can bring # 1 cylinder to TDC using a piston stop, then see if the balancer still lines up with tdc. Could you see coolant moving in the radiator? Try the other suggestion and run the fans manually so they come on earlier. Worth a try.

Also how are you measuring this temp? Factory gauge? or aftermarket?
