No oil pressure on rebuild Options

[dadsscooter]

I haven't any oil pressure on reuilt 2.0. Had run for 15 seconds and when gauge didnt register shut it down to investigate. No oil pressure was confirmed by cranking engine with oil relief valve out... NO OILl! Also pulled valve cover and it was DRY! Had installed HD oil pump and gears turned fine when installed. I did however adjust the end play after installing the pump.

I had never pulled the oil pressure control valve from the case when rebuilding. Could this be it? Could the oil pump drive possibly become disengaged from the cam??? I realize any corrective action will most likely require removing my newly installed engine but am looking for any possible suggestions to follow. Fairly new to the air cooled scene. Please respond if you can help.

Thanks, Mike

Loosen the oil filter until there's a gap. Crank the engine (with the spark plugs out and the point wire disconnected) until oil comes out of that gap. Tighten the filter, clean up the mess, crank it 'til the light goes out. Bingo! Oil pressure.

BTW, it's BAD practice to start the engine without having cranked it for oil pressure. You just put a BUNCH of wear on the bearings. The established procedure is to crank it with the plugs out until the oil light goes out, then maybe a few more seconds. After that, you can install the plugs and run it at 1500 RPM or more at a steady speed for 20 minutes, shut it down, let it cool, and adjust the valves.
