Oil Pan Gasket

I need to change the O-ring in the oil level sender. It is leaking. I understand that the sender needs to be installed from inside so the pan has to be dropped.

It appears that there is an upper and a lower oil pan gasket. Which one do I need to order? Or both? Is there more than one joint at the block so two different gaskets are needed.

I guess all can be answered by looking at the car but I am at work and wanted to get the order for the gasket going.

Only the lower pan gasket. Replacing the sump end (1021860007) at this time would be nice, but not necessary.

Be sure to rotate the engine so that the crankshaft counter weight is not blocking the oil sender unit inside the oil reservoir area. The oil sender unit pushes into the engine and it needs room so that it can be removed without damage.

In addition to wisdom already offered, I post.....

This gasket for lower sump will be sufficient.

I had this job done at an oil change, turning the crankshaft to accommodate needs....

It is the lower gasket. I used a little bit of hylomar to help seal the gasket. I didn't have to rotate the crank, I guess I lucked out. It's a very easy job in comparison to pulling the oil pan on a number of other cars (like an old porsche 944 or 928).

And while you are in there, change the sump rubber pickup and screen.
