That could be the same as the washer Colin mentioned a couple of times prior.
Colin nailed it... (See his previous 2 posts) And Mike's theory is good, IMO
VC off, washer dropped into cam tower
Over time, it works it's way through the oil tube...
And gets beat up by crank and con rods
Finds a home on the drain plug
Sounds like all is well with the engine, which is great news!

If the washer was dropped into the engine during a top-end job, it wouldn't necessarily have come from the OP's car. It could have just been in the wrenches pocket from a prior job for all we know.
I'm keeping my fingers crossed for the OP's engine health.

Is the engine running rough or is having problem now? If not, I don't think there is a cause for concern.
That washer is not much worse for wear. If it had been in the valve train or piston/cylinder, the engine would not be running now.

Ooookay. The suspect part (Colin was the first to get it) does appear to be a 930.126.135.01
PET does list two of these on the power steering pump for 993!!
I am betting once I have the engine out I will find that one of those washers is missing from the PS pump assembly. I never removed the pump, but perhaps the prev. owner had it serviced at the same time leaking valve covers were replaced?
This means the bugger likely did make its way in from the right side valve cover.
The plan now is to do a top end rebuild, and peek into the bottom end with a scope while the cylinders are off to see if there is anything terribly wrong on the bottom end. If things look good, top end goes back together and we listen hard for any noises in the future.
I really appreciate the time everyone has spent trying to track this down.

If your concerned now pull the oil return tubes out and inspect from there. Also take a look at the cams with the top valve covers removed. You can replace the oil return tubes with collapsing style.
