What is this ?
 

Doping a top end rebuild of a 2.4E

Found this in the sump plate.
Looks like it is has been cup shaped. Hard plastic.
Looks like it was round, with a bottom. Don't seems like any rubber gasket

Can not remember to have seen similar thing.
I know the engine was rebuilt in the end of the eighties.

That looks like an oil seal....possibly from the oil pump area. Might have gotten pinched when the build was done?? Just a guess on my part.

Never mind....you said hard plastic and doesn't look like it is part of the chain ramp.

Yep, hard plastic.
does not look like the round oil seals from the pump. those has thicker walls as well.
tried to put the parts together, and seems like it is round ans has a bottom

? looks like plastic (micarta) from spark plug. Have you attempted to "fit" broken pieces together to perhaps help identify original shape?

Will try to fit it together with super glue tomorrow.

Cap to something that fell in during the last assembly. Perhaps loctite from the 80's.

It is at least something that is not supposed to be there. Not lochtite cap.

Looks like a bushing of sone kind.

But for what?

Looks more like a plug. Use on new parts when packaged or on used parts when blasting to keep holes clear.

Looks like a "Cap-plug".

could be a cap plug of some sort, but this one is very hard. A cap plug would probably be a soft material?

I don't believe it has a 911 110 xxx xx part number for engine parts.

...and there is at least one more piece floating around somewhere.

Looks like a vinyl cap... Maybe someone stuck it into the dizzy hole and she fell in? Can't think of one place that this might belong.
