Where can I get debris from oil pan analysed?

[tudorsailor]

I have a Yanmar 4JH3-HTE. The short story is that I found that there was low/no oil pressure. After all common causes were eliminated, the engine was removed. The oil pick up strainer in the oil pan was clogged with fibrous stuff. I wonder if the oil filter disintegrated.
I have some of the stuff and would like to have someone look at it to tell me what it is
Any suggestions as to who might do this?

do you have the filter, is it felt or paper, if paper the fibres would be microscopically short and not able to clog a strainer, if felt , then, if you it have you can look for media losses from the filter and by pulling away samples could compare with a low power lens yourself, unless of course you are going to court then you need independant investigation. one further thought are there any felt seals in the engine gaskets??? after a long career in the filter business the only time I encountered unusual fibres in the engine oil was after a deliberate act of sabotage when somebody put a blanket like material in the oil filler.

Anything from the oil filter would need to go through the oil system to get back to the sump?
Presumably most would go through the pressure regulation/relief valve, so looking at that might tell you something?
I would suspect that the stuff in the sump is bits of gasket.
I've had a few sumps off things and found things like lengths of 'instant gasket' presumably squeezed out of joints,
A few dead insects, the odd 'spare' washer....

Could be a bit of kitchen roll or similar from a mechanic?

Are there any oil pipes which might be disintegrating? Including sump breathers etc?

Buy a filter of the same type as you use on the engine. Soak in oil and pull apart, compare with the residue in the oil pan. For both wash the 'fibres' in meths until clean, then dry.

Go and find a decent magnifying glass, better a 'Linen Glass', used in both the textile and paper industries - and compare (even better - take pictures with your phone). Post pictures here - and if you are lucky Freebee will offer an opinion.

An excellent PBO project.

We use one of a group of oil analysts in Cardiff for checking the hydro gearbox oil.
