Are you working out on the driveway extension or did you get it into the garage?

What is hanging from your brake hose?

IIRC, your exhaust was a little sleepy.  Will you be fixing that, while the cradle is out?

I was curious myself, so I went out with a flashlight and looked. It fell off when I touched it, so it was just miscellaneous debris.
I will check everything while the cradle is out.

Outside, under my home-made car port. It keeps direct rain off, but sideways rain is still a problem.

Update on what I've been doing...
I removed the rear bumper cover and jacked up the car using the metal bumper. In my opinion, this is the safest way to do it. The plastic covers the trunk area to keep out any sideways rain and the huge amount of pollen that has been falling lately.


With the car lifted and on jack stands, I rolled out the cradle.


There are a lot of little things I am going to work on while the engine is out. In this picture you can see the plug that connects the engine wiring to the power train control module that is in the car. One thing that I didn't like is that wires that were too ling were just looped back, and the loops were gathered into bundles and combined with other wire bundles inside wire looms. I cut all of these looped wires, soldered the ends together, and protected the solder joints with heat shrink tubing. There were two of these loop bundles, but I had already fixed one when I took this picture.
I also replaced two of the firewall side spark plug cables. I had done them "blind" before, and made one too long and one too short. They're all a good length now.

The firewall side of the engine, with good spark plug wires and engine wiring connector.

Those plug wires really need some protection from that manifold.  On Melanie's GP, there was a plastic channel that the wires ran through, just below the edge of the valve cover and each wire exited at its respective plug.  Due to a fire recall (the valve cover leaked, the oil got on the manifold, and caused the plastic channel to catch fire) they removed the plastic channel rather than replacing the gasket with a better one.  Once the plastic channel and its cover were removed, the wires just hung there, but they weren't as long as yours are.

Shorter wires could be used, or ther could be zip-tied to that bracket up by the coils.

The wires are not as close to the manifolds as they appear in the picture. And the one wire that I didn't change showed no heat damage at all.

I'd go with much shorter wires to eliminate the loop below the exhaust manifold. They flop around at speed.

Side view showing that the spark plug wires are not too close to the manifold.

Today I re-did all the bad wire looms, and also fixed the driver side power window on my yellow car. A poor solder joint had broken inside the rubber bellows that passes wires from the door to the car (my fault -- the power window wiring is home-brew).
