Oil wouldn't drain so...

[unfocused]

I haven't found this in the micro-fish... anyone have any ideas? LOL

My thoughts are some type of anti-cavitation sponge past it's life expectancy???
Just one of the fun things this GS is sharing with me...

No sponge. Largest pile of crud ive ever seen. Most likely clutch material I would say. Thank god you took the pan off!!!! Should just be the pick up screen there.

Never seen clutch material that colour. Looks like a kitchen sponge/washcloth but the texture will tell you.

Reminds me of a call I got from an engine customer. His 5 year old had been "copying dad" by putting stuff in the oil filler...
Luckily the engine hadn't been started - but it was a strip and wash out. Remarkable what he'd managed to get in there, LOL.

Shop rag?....

[fbody_mike]

Yeah it does look like a shop rag, I'd bet someone stuffed it in the cam chain gallery during a service and forgot about it. Looks like it was sucked right onto the pump screen. Crazy.

[gsrick]

It does look like a shop rag, but I don't think it would get into a position like that by chance. With the depressions in it, it almost looks like it was being used as a prefilter.

Looks like it's an old oil soaked pork pie, what ever it is ime glad it's not in my sump😳

The texture isn't a shop towel. And if it was a shop towel it's not only been in there a while, but it would have to of been several towels because its dense. As gsrick said "but I don't think it would get into a position like that by chance." Also, the edges of a shop towel would have to still be there and we didn't find any different texture.

I saved it just in case....

Engine runs with no abnormal noise ( my Harley has plenty of those ) Just took the scoot out for it's maiden voyage and although there is a part to full throttle issue, not once was I concerned with the oil pressure or lack there of.

[Grimly]

Either accident or deliberate.
I think we can probably dismiss deliberately putting a filter element in like that, as there would be evidence of it being a manufactured part, and I've never come across a pre-filter on a pick-up screen.
The other deliberate is sabotage - somebody shoved something into the engine in the hope of wrecking it, but what they didn't know was the GS engines with their roller bearing cranks are low pressure and almost unburstable. Sufficient oil was getting through that to keep the clockwork ticking.

+1

.....but what they didn't know was the GS engines with their roller bearing cranks are low pressure and almost unburstable. Sufficient oil was getting through that to keep the clockwork ticking.
