After zooming in
It does not look like a plug.
Maybe a gasket that is inside your spark plug socket.
To hold the plug when it is out of its threads.

I did the same (zoom in). That has a hex head shape and tapers upward ... @white2015 , I'm pretty sure you're right: its the darn rubber thingy that is inside a generic spark plug socket. I've had them fall out (luckily with the socket not over the engine's spark plug tube.)

@bresodyssey , what was the result of all this?

I guess that while he was installing sparkplugs in the adjacent cyls the rubber plug may have dropped out of the socket and into the hole. I would think he would have realized that when he put the spark plug in the socket to do that cyl, as it wouldn't stay in the socket without that rubber plug. 🤯

This was my thought process.

Great minds think alike. 😅 😁 👍 🍻

UFO stories? As long as nobody got probed, I’m all ears for a UFO story.

Even if somebody did get probed, just leave that part out.

So, aliens put a tracking device into the OP’s spark plug hole while he wasn’t looking…

… that explains why the mech didn’t know about it, with all tools accounted for.

When aliens start probing the Honda VCM engines, to steal the technology, you know we can beat them!

As long as they don't probe the owners of these vehicles, I'm good with this!

Man, I don't want to think about what those aliens would try ...

The Kids in the Hall -- UFO Alien Job Security

This is from The Kids in the Hall (Canadian sketch comedy series from late 80's into the mid 90's). At least they make it clear that the aliens seem to target people driving pickup trucks down isolated rural roads (this is why me and my Odyssey stick to them highways, baby!)

@bresodyssey , I'm just glad you're not a UFO alien infiltrator trying to wrest the "secrets" of Odyclub away from us.

We're kind of like the Knights Templar, sworn to an oath to uphold the precepts of "Odydom" (like a Kingdom, but different ...)

Anyways, I'm just glad that now I don't have to worry about being abducted by aliens and can now drive deserted off-highway roads at night in my Odyssey without aliens thinking it might be a pickup truck with a missing spark plug (if the reference to this is unclear, just see that The Kids in the Hall comedy sketch I posted in post #55 above ... I'm the first non-alien guy in the sketch, on the gurney, with the missing teeth ... )

😁 😅👍

@Buffalo4 .... and, don't forget, we're safe from aliens (for now)

The aliens told me that thing was a super duper extended reach 5/8" spark plug socket.

I only believe the "super duper extended reach" part of the scenario ...

P.S. Just found out that the amazing Canuck comedy troupe The Kids in the Hall is on Amazon Prime Video. You know what I'm going to be watching with my newly installed fiber optic internet service.
