The valve gear, and probably most of the rest of the 235 hi pressure is filthy. Little beehives of dirt on the rocker shaft supports, etc.

I'd like to get as much dirt out of the engine without rebuilding as possible, although I will rebuild when funds allow.

Right now there is no oil filter on the engine, and it has the vented valve cover.

Any suggestions about getting the crud out without a teardown? I will at least add a bypass filter, and may build an oil dialysis system for it.
