Hey guys,


2004 911 Targa owner here.


I just changed my oil at ~86,000 miles.  I always cut the oil filter open and inspect it for debris - except for the last time when I didn't have time to do it, so I saved the filter and opened it up at the same time as the most recent one.  So the debris in the attached photo is actually from TWO separate oil filters/changes.


None of the material in the photo is metallic.  It all appears to be plastic or maybe some kind of resin.  The orange/red stuff is transparent.  I'm actually used to seeing the orange/red stuff in my filters after oil changes, but I have no idea what it is.  The black particles are relatively new though...  I don't recall seeing them in this kind of volume before.


I'm not too concerned because none of it is metallic, but there's definitely something shedding some kind of material in my engine that I'd like to track down.


Do any of you know what this debris could be?

Probably two separate sources; the orange may be excess sealant breaking loose, the darker material is from the chain tensioner wear pads.  Not unusual, but I would keep an eye on things like start up noise and cam deviation values.  Eventually, the wear pads will have to be replaced.

I agree, i would plan in the distant future chain guides. They are pretty easy to replace.  Five black ones and one brown one. Clearly understanding how the cams are timed with the metal dowel and timing gear holes the dowel slide into is essential. It’s worth buying the Cam Crowfoot Wrench  and the Double “D” Cam Socket. I made my own Cam Nut Crowfoot Wrench out of 3/8” steel plate. It worked but the retail version is much better. Assbite50xx 


I would be more worried about the 1/4 dollar in your filter.
