72 318 Scamp. Low oil pressure 1 minute after startup.

Great that makes me feel better! If you zoom in on the picture you can see that the siliconed the oil pump to the cap. I should probably remove that and clean everything on the oil pump and pickup. Would you bolt the oil pump directly to the main cap. Or with a gasket and maybe permatex #2?

I really do appreciate everyone's help with this problem.
Thanks everyone.

One more question.
I looked at the pistons with a camera and I say a .040 on one piston. They appear to be flat tops with 4 valve relief cuts. Would these be stock compression pistons.
I did do a compression test and all cylinders were between 120 to 125 on a stone cold engine. That doesn't sound like a lot of compression to me.
