But yes, it is possible that you may not have enough breathers on your engine,
or the sitting around has caused you some issues with your rings.
The other issue may be that because it has been "rebuilt", it may have worn bores with new rings,
or rebored cylinders that are not round.
or even a line bore that is off centre, that allows oil to escape past the pulley.
If the engine is performing well and not making noises, and not burning oil,
I would not bother looking for anything internal.
Just add some better breathers and at worst a sand seal.
I think i may try running with the oil level slightly reduced and see what happens.
As to the quality of the builld ,the previous owner said it was done by Mullers and nothing was spared(cost twice amount quoted)New everthing.
Also it was a test and i would not normally drive it that hard.
Have also read the Judson should not be fitted before a motor has done some miles(can't remember where).
I will see how it goes and maybe fit a sand seal anyway
Is the pulley the same as a later model.
