Rear seal is easy -- pack it into place with a short bit of pipe by rolling the pipe over the seal, driving it into the slot. Push hard enough to completely seat the seal, but don't crush it.

Leave some sticking up on each side, then make a jig 1 mm thick so that you can use a razor blade or box cutter to cut the end off exactly square with the surface of the block and the pan, but 1 mm higher. Assemble. Won't leak, ever.

The key is to get it firmly installed in the slot and to leave adeqate crush -- the realy key is that the ends must be cut off exactly level. Close will cause leaks at the junction.

You must also be carefull doing it -- there is a locator pin in the center, both sides, and if you pull the seal out after stabbing the pin into it, it can also leak there sometimes. Make sure you have enough seal sticking up and the ends to cut square.
