how do you replace the Rear Main Seal?

like the title says...i need guidance please my Mopar friends...:blob1:
it is a 383

I think you just take your pan off, unbolt the rear main cap. With the crank in, I think you have to thread a tool into the old upper seal to pull it out. Then lube up your new one and slip it in

is it the same for a 440? like the thread below??

Ya I'm pretty sure its the same. They are all dodge big blocks. Just make sure you insert the new seal the proper way. Not facing the wrong way with the tapered part of the seal

 

[djais1801]

well...replaced the seal-everything back together, and STILL leaking:angryfire:

it has the billet clip in it, so it was replaced once before...and the oil in the pan is very dirty (even though i replaced it 200 miles ago)..it also has a shine to it (bearings)?

 

[mopar367]

Snap a few photos maybe, that doesn't sound good. A shine too it? like metal flakes? I don't know what to say about the leaky seal. Is it leaking around the aluminum retainer or in the seal itself?

may have my seal on 360 in backward, with the sharp edge to the inside or taper tward the engine top and bottom is that wrong and what will happen.

i did find that the sharp lip goes to the inside or front of the engine, on the 360 2 peice seal,, it is in the service manual of the truck model. Nont many instructions tell which way to put the seal in. i will use some sealer to stick it in the block, this will make the top seal hard to remove without taking out the engine.
