Heck, after the problems I had with the chains/gears/etc, I think if I dropped that damn pin, it would stay dropped. meh...the metal is soft enough. It'll get caught up in the pickup screen before it gets anywhere else. But that's just me.
At any rate, I don't think rotten valve guides are going to cause any noise, especially a chattering type noise. Shims needed? Maybe...anything's possible. The FSM and Haynes manual show the procedures for doing them. But, with the oil flow that gets to the top of these engines, I don't see how those things could get any wear on them, even after a buttload of miles, unless the engine was starved for oil at one point...in which case all bets are off.
If you've got a high RPM chatter, I think I'd be heading more for the oil pan and checking to see if the pickup screen is jacked up / plugged up, etc. If not that, then hook up an external oil pressure gauge and watch it for awhile and see what it does at higher revs. If it's starting to starve for oil at high revs, you'll know it right away.

Is it just me, or does the majority overlook the obvious?
Somebody ate a whole bag of dumbass for breakfast.
Why do people continue to run a vehicle when a warning light comes on or starts flashing? Isn't that a clue that something is wrong and you probably should NOT drive it?
Is this whole car driving thing really freekin' brain surgery?
