'89 22RE knocking in top front of engine

'89 Toyota Pickup 22RE 4WD, 200,000+ miles, supposedly rebuilt a little over a year ago (I've had it almost a year).

I drove it to work one night, the next day coming home it lost power, rattled like the engine was going to fall out of it, and by the time I made it home the manifold was bright orange.

Based on info on the net, videos on youtube that sounded just like mine, and advice from a mechanic buddy, I replaced the timing chain. I also found that the distributor cap was corroded, so I replaced the dist. cap and rotor button.

Cranked it back up and it's still making the same sound. It's a hollow knocking sound in the top end near the front of the motor. It almost sounds like it's under the valve cover, but I can't find anything wrong there. I only let it run for a minute and I noticed that the manifold was already getting unusually hot.

I searched and saw where some have had similar problems, but no one has mentioned the manifold getting that hot.
Anybody else had this problem? Suggestions? Help!

Is it overheating? I would think it would be if the manifold is getting that hot. Im a complete novice when it comes to Toyota but i would say maybe your Catalytic Converter is clogged. Good luck.
