45645, Anyone worked on GM 3.1L motors? Get your ass in here.

Task: R&R oil pan gasket.
So I got volunteered by my wife to help her coworker with her old ass Lumina. 1996, 3.1L, asinine design where you need to lift & support the engine/trans from above so that the oil pan can wiggle out.
Regardless of my angle, and lifting with the floor jack & block of wood, am I able to get it just right to get the oil pan out.
Exhaust is disconnected, A/C compressor is aside, and all the oil pan bolts are out (even that design is fucking gay - there are side bolts that secure the pan to the main caps).
Advice? I am about to just clean it as is and slap a bead of RTV on the existing gasket, but I doubt I could get it to seal.
For the love of God, help me.

I already bought the new gasket. I cannot get the pan out from its confines in the subframe though.

I actually almost had to change one of those once. I rolled under the car, took one look at it and said "Nope".
From what I remember seeing, this lumina looked like you could remove a piece of the subframe to get the pan off easier, but I could have seen something wrong or it could change from one Gen to another.
Maybe just unbolt the mounts and hoist away?

My mother has a bonneville with the same engine, I never worked on it. Has leaked from the pan but her check engine light is on.
I'll send a text to my brother He has alldata and he has worked on thes pos cars. He's likes GM-Fords both are like this.
But, most likely he would say Lifting the motor up would be the only way to change, it. I agree, just like 2000-up Ford Rangers, they're built like that also. My step father few years back had pita time replacing oil pan gasket and atx gasket.

you need to unbolt the motor mounts and lift up the motor. either that or support the motor and drop the k-member

It is, I have the motor/trans about 12" higher than its resting position.
