I'm thinking we should discuss lubrication, filtering, magnets, bearing wear, oil pump problems, different engine lube configurations etc. in a new forum.
I have an ASHWAMEGH 25/2 with a plunger pump driven off the center of the camshaft. I noticed that ROCKETBOY had a failure of the plunger return spring during the initial 250 hour hurricane emergency run in. A non India spring may be in order...?

I have several magnets in the sump, like everyone else, but I think a spin on oil filter on the oil pump discharge would be a good idea. I think the oil pump discharge check valve on the pump top could be blocked or restrained with a stiffer spring, and the plunger return spring cover nut could be bored for pipe thread. This would be the new oil discharge point. Hose this to a remote oil filter. The filter outlet goes to the oil pump gauge / prime fitting on the block. Use a Tee to retain the gauge / prime functions.
I use Mobile 40w oil because I got two drums of it for free. I know that's thicker than recomended, but the price was right!
My engine has poorly fitted grease cups for rocker arm lubrication. I hand oil the rockers with 40w. Anything better?
