...tube is loose in the hole. New motor and everything is new. Do i shim this thing or get a new one. Crank case is ventilated but it just blows the tube out. I know this should be tight but it's not. Buy a new one or what???

I'd do a new one. For what they cost, it's worth it not to struggle and fight oil spurting out. The crank is right there.
