Thanks rogoman. I combed thru the timing chain section of the FSM... the parts blowup diagram ... but couldn't see anything that looked like this piece. Went to the mechanic's today & examined the timing chain assemblies - nothing. Surprisingly, I thought it was a pretty simple setup.It may be pieces from the timing chain guide assemblies. You'll have to remove the front timing cover to verify this. If that's the case, then the timing chain probably skipped several teeth which may have caused several valves to get bent.
thanks b13er ... i guess I'll have to pass on that because I have neither the tools nor the expertise. I've asked around a few mechanics & they have no clue how the guides could've disintegrated :crying:Considering you have to heat up the head to 230 - 248 degrees just to remove or install a valve guide, yes it's going to be a pain. The head needs to come off, you need to find a way to heat it up, you have to knock the old guide out (or in your case whatevers left), heat it back up, install the new guide. Ream out the guide to 5.5 - 5.515 mm.
But it's not so bad, at least the lower timing chain cover doesn't have to come off, that's a 10 hour job.
NOTE: don't forget to get a new head gasket, and the FSM says to always install new valve oil seals. In the photo you posted, those two things are marked with a black circle with a white X.
