Hello everyone, I have found a few brown plastic particles in the oil filter of my new 986, (2000, 2,7L) but no visible metal abrasion. However, I would classify the amount of plastic abrasion as not critical but still worthy of attention. Does anyone know the internal engine structure and what is made of brown plastic, possibly the chain rails?

Yup, chain tensioner pads.
