which will be trial and error, by screwing down the regulator a bit at a time until the full oil reservoir takes an hour to an hour and a half to reach empty

no different than an adjustable displacement oiler, or even the cylinder lubricators of the big marine twostroke diesels I used to work with...

Setting lubrication rate on those took me several days (engine running 24 hr/day) if I had to do it inbetween jobs, and at least 5 or 6 hours if I could focus on just that job alone (which was rare...).

I am not THAT kind of engineer that I know required ring compression under different condition, but I DO know this: If a ring is NOT compressed, it won't seal, and it also won't build a seal under pressure. It will start to flutter, and "steam cuts"...

Personally, I would stick to the Teflon piston rings. I know that O-rings can work, several brands apply that tech, but it would not be my choice.

Here is a better photo showing the pipe the carries the oil from the valve at the top of the steam oil reservoir to the metering valve and into the steam line.


The reassembled oil pump was reinstalled and connected to the engines crankshaft. Then using a cordless drill to slowly rotate the engine the operation of the pump was checked, oil passed up the pipe and to the regulator and also out via the overflow back into the oil resivoir - success!


No, not success, the oil did not enter the steam line, the regulator was either blocked or closed. I therefore dissassembeled the regulator, cleaned it and reassesmbled it. I then set the regulator so I could hear air passing through it, knowing this would allow too much oil to pass. When I turned the engine over again, oil passed into the steam line, so 3 problems with the oil pump had been fixed.


The last job with the oil pump is to finalise the the oil flow to the steam line, which will be trial and error, by screwing down the regulator a bit at a time until the full oil reservoir takes an hour to an hour and a half to reach empty
