Sigh, I'm one of those poor slugs who has replaced mine with the motor still in the car - I jacked it up as high as it could go (after unbolting the motor mounts and transmission mount) then unbolted the pan and let it drop as far as it could go. Well, thank God they make one-piece oil pan gaskets that now have metal down each side! They gasket also came with these 4 little threaded plastic plugs that you install in the four larger bolt holes. You can then slide the gasket under the front pickup then the rear pickup and the fun begins! Get ready to cuss...throw tools....cuss some more...attempt to stick those stupid little threaded plastic plugs into the four, most difficult to get at holes then you get to pop the gasket up over the plugs...then the pan...cuss some more because the stoopid %@$^% plugs bend and or fall out. Finally, after a few wasted hours of time, you eventually pop the pan up over the plugs. Oh, wait...now you need to remove them! I guess what I'm trying to say is that hopefully you know someone who owns an engine hoist and just pull the bugger!!!
Good luck....oh, and when you remove the motor, replace your rear main seal too!
Cheers mate!
