Oil Pan removal

Yes you need to lubricate the gears and fill cavities with petroleum jelly before installing pump. Have to remove the front cover and oil filter adapter, gasket, pressure regulator and valve from front cover to access pump. Here are the instruction on how to remove the oil pan in the diagrams below.

Hello and thanks for donating

The purpose of this molded style gasket (AKA one-piece gasket) is that they seal much better than old styles and they are reusable. They don't stick to the oil pan, you can remove it, clean it and the pan and reuse it. They do a great job, I have never had a one piece leak yet. You can still use the old style which is obviously much cheaper, just an option to choose.

Yes, it has multiple purposes really and when the oil splashes up it just breaks the oil down faster. These types of seals are relatively new, cars have been without them for many years. It's not a mandatory part, its just a better option as stated before. They eventually wear out due to the amount of stress and heat they endure, that is why sometimes they may get a leak.

Hi Chris,

I am not sure of any specific tightening sequence on an oil pan. I have never looked for one and of course never used one.

Anyway, here is how I tighten oil pan bolts.

If using the Cork gasket - Snug all bolts - Then tighten one at a time till the Gasket just starts to Squeeze out at the bolt. Drive vehicle for about a week and check gasket may need to retighten.

If using the Rubber Gasket - With some of these type gaskets they have metal gromets so you cannot over tighten - If doesn't have the Metal Gromets do same as with the Cork except when tighening let it squeeze out a little more. And you won't need to retighten as with the cork.
