904 Pan gasket problems

[Bigreno]

Can someone tell me what the indentations at the rear of the pan are there for? I'm trying to put a new gasket on and every time I start to torque the bolts the gasket wants to squeeze out whet the indentation is. I used a rubber gasket and Versachem gasket shellac.

Yeah, I had about decided their only reason for being was to aggravate me.

I actually welded mine up! Made it straight. Ended up using a pan from a Durango with a filter extension and the gasket I mentioned. NO more leaks. MT

Could it be that your pan is not flat and you are inadvertently over-tightening those two screws? The gasket squeezes out because there is no pressure from the pan to retain it
If the pull-through on the bolt holes hasnt been repaired that will just make it worse.No gasket will seal until these issues have been addressed.

The "indentations" are stiffener ribs.On non-cork gaskets,they also act somewhat as labyrinth seals.When cork gaskets are used, the cork expands into these areas and locks the gasket to the pan.

THIS ^^^^.

I got fed up with messing with gaskets, this gasket is the ticket, an re-usable.

You should be able to get it at your local Chrysler dealer, that's where I got mine.
