P1325 & green rubber plastic bits in the oil - Is the end near?

That green stuff looks exactly like my chain tensioners that I replaced when I saw pieces of them in my oil when I purchased the car.
How does the car sound at startup for the first 1-2 seconds? Do you hear the chains before the oil preloads the tensioner? If you hear that sound, then you may have a common problem that's not the end of your M96.

The cam tensioners were light beige to brown plastic not green on my '98 base. I did have green camshaft end plugs, so it could be that someone in the past popped one (or part of one) into your cam cover when removing them.

I would suggest using a magnet to see if the apparent metal particles are steel. That's a bigger issue if they are. If they are aluminum, one of your tensioners may be bad causing a timing chain to scrape the casing. This will throw a code, if it is the problem. You can take off the cam covers without removing the engine and replace the cam tensioners if that's what is bad.
