Junk in Oil - Help Identify

[Bristol]

I haven't been driving my Boxster much (2000 Box S). Yesterday I finally got around to changing the oil again. It's been 19 months and 6,800 miles. I found a LOT of the little olive green rubbery bits in my filter that others have seen before.

But I also found some longer pieces of white rubber.

Just to be safe and investigate further I dropped my oil pan and found a very minimal amount of both types of pieces there. Some of the longer white stuff was stuck up on the oil suction screen though, so I was glad I dropped the pan and cleaned it.

I'm not going to freak out. I only found one speck of metal and just a few specs of the dark brown glassy material from chain tensioners. So I'm guessing that some sealant or o-ring material just got chewed up in the engine. The car is running fine and not leaking oil. I saw someone else suggested the oil filler tube o-ring. That's the only place where I have a tiny bit of an oil leak. I'll have to see if I can take that apart and check it. If the o-ring was bulging inwards I may have snagged it with the dip stick and forced it into the engine... but maybe then it'd just float around in the pan and not get chewed up.

I'm going to run the car for another 6,000 miles and just check the oil filter then, maybe sooner if I lose any sleep over it.

Any thoughts though on the white o-ring like material? There is a definite groove in the material where it seated against something. Where would that have come from?

Spark plug tube seals? Someone might have replaced them and they broke off inside?
