Any body know the oiling circuit for an M42. I know it's picked up from the sump into the pump on the front of the crankshaft/front cover.
1) Where does it go from there?
2) Does all of the pressurized oil go through the filter first?
3) Is there a bypass in case the filter clogs?
I would only trust a system where the oil goes through the filter and then a cooler that used steel braid lines and aircraft spec hardware. It would also have to be maintained constantly as debris (like timing chain tensioners, etc. in our case) could clog the lines and/or cooler. The pressure gauge would need to show the actual pressure entering the engine - not leaving the filter.
