alright guys, need some advice here, let me know what ya think.

Im in the process of rebuilding the Motor in my John Deere Liquifire, now this is a rather opinonated answer so i dont expect to see a "right" or a "wrong" answer, just some suggestions. Now for the question.

Im using a silicone gasket to seal the crank case with, but do i put the silicone on the crank seals also or leave them dry?

This summer we put to getther 2 engines that were split, and we used silicone for a gasket, but we never put silicone on the cranks seals, it s not needed because when u get im in there they're in there pretty good.
just my $.02

Ride Polaris!
I would vote No. Even if you use a oil compatabe silicone it is difficult to clean off the surfce next rebuild. Even worse if something goes wrong and you end up splitting the block again before completion.

"Meaningless Ride"
Even better than silicone for the crankcase is Yamabond-4. That is what is reccomended for assembly of the crankcase. I leave the seals dry.
i guess in my opion, and from an automotive point of view, i would say you shouldnt have to put sealant on your crank seals. like it was mentioned before, it would be a mess if you ever tore it done again to remove the sealant,
No sealant on the crank seals...and I second RXLRIDER...Yamabond is great stuff.
