New motor blowing oil on headers

Thanks for all the info everyone! Here are some pics of my balancer in relation to timing cover. Im pretty confident its not seated all the way.
My carb is a 950 XP and there is no where to hook up a PCV system. Im running an Edelbrock supper victor intake which also has no vaccum ports. Is there another option for crankcase ventilation? I looked into vacuum pumps but I'm having a hard time finding any kind of mounting brankets.
As far as the sealer around the crank and balancer, what type of sealer should I use?
