I ran a newly rebuilt motor today with oil return pipe removed about 3 minutes no oil came out side cover return hole ? thinking oil pump is weak ? or just it take a long while to fill oil galley ?

It also overflows onto the cam/crank gears as it is open at the front. Open the cover and start it up. You should see plenty of oil or something is wrong.

Something is most definitely wrong!

Did you dump a quart of oil in the distributor hole before you started the engine or did you run the engine 3 minutes on the prelube on the bearings?

I feel that it is always a good practice to rebuild your oil pump (or use a new one) when you rebuild an engine.

Thank goodness.

If you remove the valve cover, take a look at the square hole (RED ARROW) that overflows oil to the timing gear. MANY engines have that hole hacked and broken at the bottom like the red dotted line. The engine sits at a 3 degree angle in the frame. For the oil to flow backward over both the first dam and the timing gear while parked at idle, the bottom edge of that hole must be level with the first dam (blue line) while the engine sits at its 3 degree angle. If the bottom of the square hole is too low, the oil flow at idle will never be sufficient to back-fill the chamber to the return pipe.

Ignore the pressure lines in this photo.

I installed a rebuilt engine a few years ago, and the instructions with it from the rebuilder said to allow about 2 1/2 minutes maximum. I had rebuilt my oil pump myself and it always seemed to take over 2 minutes, so I installed a new pump from Brattons. Now it's about 30 seconds. I also bought a beat-up oil return tube at a swap meet and cut a 3" section out of it and installed a 3/4" ID section of clear tubing I bought from Home Depot with a couple hose clamps. Now it's really easy and clean to check oil flow...good view of timing and amount.
