It is looking like careless, dirty workmanship by whoever worked on the engine last. Stinkwheel may be on the money, too.

Both the feed and the scavenge drain plugs should have a metal gauze filter, part number 140052 for non-metric crankcases. Item 57 in the parts book drawing.

Enfield seeds........plant one, see if you can grow a new bullet?
PS, how on earth did they get into your engine??

From looking at the messy apperance under the rocker gaskets it looks like the crud could have come from anywhere.For a rebuilt motor you only need new gaskets no gasket goo.
I have an opinion on the sump gauze too,and that is it stops very little,i have measured it up in length and it comes up 1/8"
short of sealing at the top when screwed in,I have seen big end white metal chips in the rocker galleries (blocked solid) and couldn't come up with any better explanation.Any theories welcome.

There was a spate of owners fitting additional oil filters to their rocker feed pipes on Bullets a few years ago, blocked rocker feeds can lead to other more serious failures.

The gauze strainers also don't do a very good job when fitted to the Electra-X of protecting the scavenge oil pump body (which is actually the timing cover) from getting scored by the smaller bits of failing big-end pin, sump magnets are advised!

Regarding the gauze filters, on Redditch machines at least, they usually 'top out' as you screw them home and often come out looking a bit twisted and crushed, so these at least, are obviously long enough to close their ends on the top of the chamber.

Maybe someone took mineral oil very back to basic? I don't know..
But does remind me that there was rice in the original exhaust muffler..

But, when rebuilt the engine from new, it is good to pour some oil in the sump? Now it is dry..

More like badly reassembled version, I would think ...
