rear main seal

[snipes243]

I was figuring why i had everything out to swap transmissions I would replace the rear main seal since it a little leaky. Any advice on how to do it without removing the engine.

With the trans out you're staring at the rear main. You still have to drop the oil pan. That puts you into a new pan seal.

I think he's worried about the oil pan clearance. Not sure how much room might be there with the 351. Might need to support the nose and lower the axle down. Any guesses?

I think it will just barely clear, i was looking at it tonight. Any tips on installing the actual seal?

[Timstrk]

Don't you have to drop the crank to do the main seal? Engine would have to be supported without the trans connected.

Depends on engine. Older use the two piece seals that require the crank be loosened, not dropped. Newer engines are one piece and require nothing more than removing the flexplate or flywheel.
