How do you install new Oil Pan gaskets when the Engine is still in the car?

Thanks for a reply.

• Remove motor mount through-bolts
• Jack up engine a few inches (crank just behind harmonic balancer is a good jacking point)
• Insert lumber between motor mount area and frame to support engine
• Remove oil pan screws
• Remove oil pan
• Remove oil pan gaskets (jackhammer and flamethrower recommended)
• Clean surfaces
• Install new gaskets, using RTV at junctions, and possibly smearing everywhere else, depending on preferences
• Reinstall pan and tighten screws
• Lower engine and reinstall mount bolts
• Consider changing timing set and water pump while the pan is down, since it has to come down at least a bit to remove timing cover

While it's possible, once you go through all the steps called out in the CSM, you're only a few bellhousing and torque converter bolts away from simply pulling the engine. You'll be MUCH happier if you just do that. It's a whole lot easier changing the gasket with the engine upside down on a stand instead of trying to do this under the car while oil is dripping in your face.
