Something peeling in the engine?

[gator67]

I was doing a "pre-flight" check when I noticed something in the engine that doesn't look right. I am not a mechanic so my descriptions may, though not intentionally, be humorous to you. This is a picture of the left side of the manifold(?). Notice the protrusions just above the center of the picture. The left one is smooth, while the right one is peeling.

Here is a closeup of the one that is peeling.

The metal under the peeled plastic(?) seems to be fine. What is this that is peeling? Is it okay? Is there something I can/should put on it to make it neater?

Jerry, It looks like something was dropped on top of the right exhaust manifold bolt stand-off (spacer) and was melted by the heat. Try to clean the "STUFF" off of the bolt stand-off and look up above it and see if something is dropping onto the stand-off from above.

Good luck - Glenn.

Looks to me like a dead and fried June Bug.

It's definitely something that fell or landed there and got fried. That's no reflection on the integrity of your exhaust manifold, which is just fine. I'd take a peak around the engine compartment though (especially above that spot) to see if something plastic is missing, like a wire tie or plastic washer that holds insulation in place.

It looks to me like something with a cloth nature, which makes me think of a small piece or scrap of fiberglass.

I would suspect some of the insulation from the partition or panel above the engine.

I've found scraps of fiberglass that look amazingly similar in various and sundry places around the two caps. Yours just looks a little more "toasted" than mine.
