Re: Help w/ rear main seal replacement

I don't know. I'm not even sure how to get to it. I guess I kinda expected it to magically be there and I could change it. I bought the 2 replacement parts and they are both 2 piece double lip. One is offset, one is not. I was going to compare them to the one that's in the engine now and return the one I don't use.

Yeah- that would require a totally different approach if you have an '87- up block.

Re: Help w/ rear main seal replacement

The "heavier" lip goes inwards. The offset seal is only needed if a groove/ rough wear is found on the crank.

Quickest way to tell if you have an old 2- pc. seal block is to look at where the flywheel bolts on. If you can see the bolts protruding thru "open" holes, its a 2 piecer'.

Ahhhhh! I was wondering what the difference between the 2 is.

Re: Help w/ rear main seal replacement

The block is a '74 so I'm good. So now I hope I can follow your directions w/o screwing it up. Thanks!
