Oil pressure was what I was getting at. I'd put a filter and an oil pressure gauge on it and ride it! Don't take it apart!
There is a conundrum here .
A full sludge trap may boost oil pressure ... the measurement is before any oil is used .
it tells you the pump is working and the seals ... up into the crank are too .
you would have to fit a gauge
after the sludge trap , rods and drive side bearing ... to know how far useful oil pressure or volume is getting .
