Engine reminded me of my old 1935 DX Vauxhall with those side covers...
thinking about it, they were probably closely related.

Make sure you blow all the oilways out with compressed air when you are done cleaning it, especially the one's in the crank , its amazing what gets in them once you clean things up! Shocked Shocked

Yes, it's interesting how bearings are lubricated. I used to think that you needed oil pressure to cushion the impacts on big ends but apparently the forces present are much greater than those generated by any oil pump and it is this dragging of oil into the wedge that counter acts the combustion pressures and prevents metal to metal contact.
