This is my first dry sump engine . Should there be a check valve of some type
in case blow-by exceeds the suck of the oil pump ?

Hi John
That will never happen unless your rings are shot. With a dry sump you can
run low tension rings for less friction and more usable power.
Don't run any vents on the crankcase as this will reduce the crankcase
vacuum and you want all you can get. Crankcase vacuum allows the rods and
pistons
to move more easily as things move through a vacuum easier than at
atmospherical pressure.
Definitely vent the dry sump tank and I recommend a puke can on the vent
hose to catch any oil suspended in the air.
