Rope or Rubber rear main seal?

Like green1 said don't put the seal flush with the block and also the main cap. Rotate it just enough like he said to have the 1/8 inch sticking out of the block and also out of the cap and that way when you put the cap on, the seam where the two pieces meet will be "inside" the cap and block where it can't weep out at the point where the cap and block mate. I had that happen to me even with putting a little sealant where the two pieces mated together. I learned after having to pull it back apart. It wasn't a big leak but oil leaks drive me nuts and I wasn't going to just live with it. So far it's been leak free now for a long time. Now that I've said that, you watch, something else will start leaking! ERRRRRRR!
