Quest for Timing Chain Rattle, part Three

[misnomer]

OK, I've pulled off the valve cover and upper timing cover. The rattling seems to be the chain against the guide opposite the tensioner. Now to figure out what to do about it, and what to replace. . .

The upper timing chain itself seems to be in good condition, no noticeable wear. The motor has 150k miles on it, I bought it at 107k, but dunno if the timing chain was done before I bought her. It seems that way, I'd expect a 150k mile old chain to be more worn :P

Anyhow, I'm mainly looking at what I should replace to solve my rattle. I assume the upper tensioner. Can't find a part at CourtesyParts for the guide on the other side, though I figure I'll replace that as well. The upper guide has been gone for a year.

While I'm this far, do y'all figure I should drain the coolant and pull the lower timing cover as well?

Either way, I need to consult my service manual :-) (gotta find out timing for when I put the distributor back on as well).

If there is enough interest, I'll do a writup of the process.

Cliff notes (for you lazy sons of bitches out there):
