Slant 6 oil pressure woes…

That's a standard one quart filter.
Yeah Charlie pointed that out. I’ll probably drain some oil out tomorrow. My dad is gonna come help me out and I’m gonna drop the oil pan and see if the pickup screen is plugged up, and probably just replace the oil pump entirely while I’m down there. But since the pan has to come off I’m gonna drain the oil anyway so I’ll just put less in it when it all goes back together
