Edit: Solved, it is a fragment of my Wix 57211 oil filter that I cut open with aviation snips to inspect the pleats. That is why I didn't see the fragment until much later in the waste oil pan, and I jumped to the wrong conclusion...
This is from when I dropped the oil sump pan cover to install the EBS Racing baffle. The oil pickup tube had little
snakes of sealant in there, and there was also a piece of plastic jammed on the outside of the screen. This was the piece. [Edit: it was not the piece, I jumped to the wrong conclusion, this piece was 7mm a side, the bit I found in the screen was much much smaller) this piece was from an oil filter I cut open] I didn't realize it had a number on it but when I was changing the oil on my mower the other day I saw it as I was draining the oil into the pan and realized it had a number.
It is small enough that I wasn't too worried, but now that it has a part number, suddenly I got very worried
I have been reading about exploded chain pads; not fun. Also I figured with there being a part number, that would identify the area of the part that was wearing/failing. I figured it was one of the chain tensioners or pads, but none of those part numbers seem to have 557 (as far as I can tell)
So I started hunting around, and found that the oil pickup tube ends with 557. I removed my oil pickup tube when I was cleaning out the sealant, and it looked totally fine to me, with no broken off areas. In my service history I don't see any work done in that area, but then again my history only starts at 60,000 and the I don't believe the sealant on the sump pan was factory. Maybe there was an accident (previous owner drove over a curb and struck the oil pan cover, and it got replaced but the mechanic missed a piece of oil tube plastic?) I am just brainstorming ideas. This fragment looks flat though, and the oil pickup tube seemed to mostly have curved areas.
Does anyone know what this is? or have a new oil pickup tube to see if it has a part number printed on it like this? (called "suction tube") part # 99610707557
It is on this diagram:
Engine Lubrication
Does anyone know of any other plastic parts that have "557" in them besides the oil pickup tube where this could have come from?
thanks,
Steve
PS Searching the various parts resellers for parts containing 557 does not work... blah.. I did find
this search that lists every Porsche part that has 557... it is a lot
