Oil pickup adjustment

If the pickup moved that far it was set wrong to start with.

That style of pickup is designed kind of like the OE pick up. By that I mean you set the pick up to just touch the pan. That's what that little strap is for on the pick up. It should just touch the pan. And if that was the case, it would never turn that far.

So set the pick up so it touches the pan and run it.

I don't know how you use a jamb nut on pipe thread.
