Re: 350 rearmain repair
With my factory 350 & crossmember I could not simply drop the pan. I found this out the hard way and sence I had all the bolts out of the pan and I had the same leak you speak of..I had an idea
 so I dryed the pan gasket as best I could and added black RTV, as best I could, not much room in there. I added a bit extra to the rear. Drank a beer while I let is cure for a few min, bolted it all back up and no more leaky for a few years  I know I know it's not proper way but heck it worked! hahahaa

Re: 350 rearmain repair
You definitely need to unbolt the motor mounts and jack up the engine to remove the pan. Be sure to keep an eye on your distributor and exhaust manifolds, as they will contact the firewall when the engine is raised. This is how I did mine.

Re: 350 rearmain repair
I got quoted $550 for a rear main repair - $300 sounds like a bargain...

Re: 350 rearmain repair
You need to unbolt the motor mounts, and jack the motor up a good bit. Then the oil pan will come out. If you are doing this on the ground, I would caution you to be very careful. What I would suggest is to get the motor up, and then put a block of wood under the mount area, just in case it slipped off of the jack. If you have access to a lift make sure you do not raise the engine so high that it picks the truck off of the lift. Access is great once the oil pan is out of the way. I have done a few of these, and for 300 bucks, I would suggest you not getting dirty. Sometimes those seals can be fussy coming out, and experience is priceless.

Re: 350 rearmain repair
I agree, jacking the engine up is no fun and i had to replace the rotor in my distributor after it hit the firewall and cracked. Definitely save yourself the time and frustration and just take it to the shop...
