I have an obscure question for the OG's. I had tons of oil leaks in my 401, I fixed them all but the rear main i didn't want to mess with and farmed it out. When we looked into the oil pan there's a half circle rub mark where the pickup tube rubs on the bottom of the oil pan. I've never seen anything like this before and it seemed like a problem to both of us. How close to the bottom of the pan do you guys set that pickup tube? It seems to us that some of my oil pressure trouble could be the pickup tube being so close to the bottom pan. Just wondering if there was any wisdom to be had on this one.

Typically it should be right around 1/4" to 3/8" of clearance. If its too high it can starve because its above the oil level (especially on corners), and if its too low it can starve because it can't get enough oil.

If the pickup was touching the bottom of the pan, your engine was definitely being starved.

You can use a piece of putty to check the clearance. Put it on the end of the pickup (solid metal part, not he mesh), and bolt up with the pan with the gasket in place. Then pull it back off and measure the putty.

Ok good, thank you. That's what we were thinking and your spacing advice is right where we were planning to put it. Much appreciated.

the original pick up tube snorkel has a plastic round spacer facing the bottom of the oil pan, with corresponding receiving hole in the pick up tube snorkel. It size is close to as said above , but it is not riding on the bottom of the pan...
