Took running but leaky engine down to the short block and cleaned everything well. Replaced all gaskets, set valves to spec, chased all threaded holes and reassembled with all new seals and a new electronic distributer. Discovered oil pump is 180 degrees out of rotation (common problem, just matched the distributor to it) but it started fine and idles well. But it has some clacking noise on the manifold side I am thinking is tappet noise and it gets hot quickly. Also pops a bit when you open the throttle. We are thinking the timing may be too advanced, causing both the popping and it to over heat. Can't see the timing mark in the hole underneath so just setting timing by ear. Flywheel could be 180 degrees off as well which means pulling it back out of the Jeep. Any other ideas before we do that?
