Okay, I degreased the engine a few days ago, and found my oil leak to be some where above or in front of the starter. The only part that I can think of is the dipstick tube.
From the top of the engine I can move the dipstick tub back and forth with very little effort. The valve cover gasket is new, and I can’t think of anything else in that area that can leak. Checked the pan gasket, knock sensor, and the top of the engine behind the intake is dry. I don’t think it’s the rear main because it would leak from the drain hole in the bottom of the torque converter cover.
The starter is covered with oil. Anyone have this problem before?

I'm sure it shouldn't move easily. And I'm betting there should be a gasket/O-ring to seal entry into the block.

There's no gasket or O ring, it's a press fit. Doesn't take much effort to install it.

It should be pretty tight and there should be a bracket welded to it which bolts to the exhaust manifold or somewhere to keep it from moving around.

Check out some other similar cars, see what their setup is.

It shouldn't leak from here if you have the right tube
