As long as the heads aren't damaged beyond repair it should be an easy fix..

Messed up?
I may have screwed up.
I labeled 12 large food storage bags 1a, 1b, 2a, etc., and saved the rocker arms, screws, and push rods, from each cylinder, to the appropriate bag.
The extra, shared, piece was saved to the "b" bags.
I saw, in the Haynes manual, where people use a box with holes in it for the push rods, but I wanted to keep everything a little more manageable, in case someone should happen by and take the push rods out an look at them.
The book only mentioned putting them back in the same place.
It didn't say anything about making sure that the "up" end stayed up.
Is this an issue?
I've only done the front bank, so far.

I've never done this, but I would think that the wear on the top of a pushrod would look different than at the bottom, due to the fact that the rocker arm is pivoting against it. Might be very hard to see though?

I think the bottom of the pushrod will have a very uniform wear path, the wear path of the Rocker arm end should be a little longer...

Broken Piece
While at the back of the manifold, I managed to break the top off of this piece.
It has a plastic tip which a connector goes on.
This is just above the engine to transaxle bolts...just below that big hole at the rear of the plenum/intake manifold, directly below that hose nipple tree, above that big, shiny heat shield.
The stem is still intact, inside that white circle of plastic.
It appears to be threaded into the top of the "bell housing"...if that'* what you call it.
Anyone know what this is called?

So...can I just stick the probe back in the stem and glue it?
...or does it have to be replaced?

It'* a *-l-o-o-o-w-w go.
I'm taking pictures every time I take something else off.
Like so:
...just in case I forget where something goes.

Yep, I remember from having LG3 87 ciera, 1 sensor for the ECM, 1 sender/switch for the dash light or gage, and 1 backup sensor set to a higher temperature to directly turn the fan on if the ECM fails to do it.
