Oil pickup to oil pump gasket
 

I used a very small bead of black rtv instead of the paper gasket that goes between the oil pickup tube to the oil pump. (I thought I had ordered the gasket among the other 45 parts I had ordered but it wasn't in the box and I had already put rtv on the oil pan).
Should I take the oil pan out and use the appropriate gasket or would rtv be OK in there?

Use the appropriate gasket. Hopefully none of that gunk finds its way into your pump screwing with the pressure relief valve. Often times, when squished, the silicone beads up on either side of the mating surfaces and might be in the direct line of oil flow.

I have a spare gasket if you like to use it

Got the oem gasket from harold and reinstalled the oil pan. All is good
