I've fitted a couple of those kits and have been somewhat underwhelmed.
Firstly you have to be VERY careful with the rear cap machining alignment,
definitely a case of measure twice, cut once. I would strongly recommend
that the cap is in place on the block for this operation.
Secondly I was very disappointed to find that the designers decided that it
was just too much effort to utilize the 3 tapped holes already in the block
to secure the upper half of the seal holder and instead required that one
drill and tap 2 more holes for that purpose.
Thirdly, and I appreciate that there is possibly no way around this but,
the scroll on the crankshaft has to be machined off which is something that
you should have your crank grinder do when the crank is being machined. I
did mine in my 8" lathe and it's pretty scary having that huge hunk of
steel spinning between centers (don't forget to disable the chuck brake ...
rather frightening to notice the chuck winding off the spindle as you power
it down=F0=9F=98=B3=F0=9F=98=B3).
Finally, after all that effort, there was still a small leak from the rear
main which I finally resolved by installing my PCV.
kit.

In future I'm not going to bother with the seal kit and just fot the PCV.
