What is this ?

[Deleted member 20330]

Prior to my current experience with fixing problems myself, I took my Gen 2 to a shop to diagnose a noise and power problem.

The mechanic said a spark plug had blown out, which he removed. Since the shop didn't perform stripped threading repairs, they recommended replacing the head. I didn't since it was cost prohibitive.

I had the car towed home rather than driving without a spark plug.

When I looked at the spark plug threading, I was able to remove the single item below in the first three images. It appears to be made of a rubberized material. I speculate this is something that fell in when the mechanic removed the blown out spark plug.

The last image is of looking down into the cylinder. If you zoom in, you can barely make out the characters "A 6". Is this a serial number on the piston ?

Looks like the rubber bumper at the bottom of the coil cover plate that covers the coils on each valve cover.

It's meant to put pressure on the ignition coil once the cover is installed and bolted down.

98lincmk7lsc,

Bits of the driver side valve cover did fall apart when I cleaned it. To keep the corresponding coil pressed down, can I use adhesive to put this back or is there a bumper kit I can get to replace them all ? Or should I not be concerned about this ?

Can you make sense of the last image ?

Are the characters "A 6" stamped on the piston or is this something from the blown out spark plug I have to clean out ?

I don't know if there's anything stamped on the head of the piston, but if you cant see any edges to what you're reading it off of , chances are it's too big to have fallen into the hole, and is most likely the top of the piston.

As far as using something to hold that coil down, I would guess that a small piece of thick rubber would probably work fine. Another option I can offer you is to buy another set of coil covers. I have at least 4 sets of them sitting in the garage, and would sell you a set (with those rubber pieces intact) for $25 shipped, as long as you're not located in another country. That would probably be your best option, to prevent this from happening again.

98lincmk7lsc,

That helps a lot since I was concerned the coils wouldn't be pushed down enough.

I'll add it to my purchase list.
