oil pan gasket change writeup needed.

[lookbutdonttouch]

i do apologize if this is a noob question, i looked around and diddnt find what i needed,

i want to change the pan gasket especially, but wanted to do the motor mounts while im at it. i saw how to do the mounts, in the tranny area, but it uses the oil pan to lift the car, so how would i change the pan gasket, what do i use as the lift point for the motor, to get the pan off?

thanks in advance
ryan.

You could use the engine lift brackets. In other words, you're most likely going to need a cherry picker or come-along. Here's how I did mine (obviously I was doing other things as well.




You will need to lift it a good few inches to be able to get the pan off of the engine. I'm pretty sure you will also need to remove the engine-to-trans brace, and it is a REAL PITA. There are 2 bolts up between the engine and trans that are very difficult to get to. A ratcheting wrench and small hands are very helpful.

I built an engine lift out of wood that mimics the GM engine lift. I don't mind sending you pics and measurements to build one of your own.

Not sure if this'll work.

Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

I grabbed it from http://www.sourcenet.ca:9001/servlets/Home .

I'm just going to pull my motor and do it while it's out. Should be easier. .

[lookbutdonttouch]

wow thats quite intense, thanks for the help. i was thinking it wasnt going to be quite that crazy, as doing the mounts diddnt seem too bad, and one mount blocks the pan from coming off, so i thought there was a trick to make it easy that someone had come up with.

ill give it a try,

do i just need the gasket, or is there anything else in there that should be replaced while im at it.

thanks for the help, man i wish i had a garage, for now i have the curb.

I have my oil pan out on my 96 firebird 3800 and am wondering about this gasket never seen one like it and it is really making it tough to put back pickup tube is there a normal gasket or can I remove this one and just use RTV.Anyone know what this kind of gasket in there for?Also while I am here when I replaced engine after it was rebuilt the oil pressure is almost nothing at idle up at 60 when revived to 3000rpms then back to nothing took off one valve cover nothing at idle shoots oil out of push rods at 3000.
