    I think I need to replace my rear main oil seal. I believe that it is a rope style. Can I replace it with a 2 piece or do I need to go back with a rope? I've replace rope seals before and they are a pain in the beehind.

    Yes, you can and should. Its a neoprene seal made by Fel Pro, I got mine at Advance Auto Parts a few years back, I would imagine they still stock them.

    I used the 2 piece seal and it was simple to put in.

    I ordered one from G.M. and it was a 2-piece rubber seal.
    I dont think they sell the rope style anymore. /forums/images/graemlins/k5.gif /forums/images/graemlins/thumb.gif

    When you did the rear main was the engine still in your truck or did you remove it entirely? I am probably going to need to replace mine soon and was wandering what is the best way to do it with the engine still nestled in my M1008. Any help is appreciated. /forums/images/graemlins/truck.gif /forums/images/graemlins/thumb.gif

    When installing the 2 peice seal this is GM's recommendation. Install the seal with the ends at the 2 o'clock &amp; 8 o'clock, or 4 o'clock &amp; 10 o'clock positions. They recommend indexing the seal ends from the 3 o'clock &amp; 9 o'clock possitions of the main cap.

    Hope this makes sense.
