Found some gasket type residue in oil filter - help !!!

Hello,

I am trying to get some feedback as to what the rubber residue in my oil filter could come from. It is definitely not metallic, it is pliable, has a rubbery feel to it and the color is olive green. It looks like a gasket material.

It started to appear during last oil change 6k ago. My car is a 2000S with about 55k miles and always maintained perfectly.

I thought it might be the AOS but I replaced it and the diaphragm which has the same olive colour was intact.

I was told that when the previous owner had the valve cover resealed maybe they used a green compound but I checked the engine and the gasket material is black.

I am running out of idea where is this coming from?

Please anybody can help?

Thanks in advance

It looks like the sealant used at several points in the engine by the factory and some dealers during repairs. We see it from time to time, breaking loose from too much being used during assembly or repairs; I wouldn’t be overly concerned about it….
