Oil Filter Housing Surprise

[78F350]

Here's a pic of the big chain ramps that lead up to the heads. Note that the cracks can often form at a sharp right angle. Color is dark brown, not black.


Here's the chain guides on the cam chain adjuster. I don't think the fragments are from these.


I have a partially disassembled engine if anyone has a suggestion of another part to look at.

It’s hard to tell from the OP pics, but notice he has one on its edge so you can see the “s” curve that each piece has (if you look closely, you can see the curve in the others, as well).

How do the scavenger pumps work? I seriously doubt that they have plastic vanes, but just an idea.

Anything in the oil filter first has to get picked up from the sump, pass thru the oil pump pickup screen then get macerated thru the oil pump, not much chance of that happening with pieces that large. What type filter housing are you running?

Hi, this is the housing on my Boxster.



Thanks

I'll offer you $1,500 USD for your broken Boxster.
...But, I think you just need a new oil filter canister.
Old style is smooth on the bottom:

New style canister has vanes at the bottom:


Vanes are "S-curved". Vanes are past the oil pick-up screen. Get a look at the bottom of your canister. Broken vanes?
