Wendell, I can tell you from personal experience, if there is even the
slightest air leak in the pick up tube or attachment to the engine, the
sucker will just suck air and won't pull oil up (at least at cranking
speeds).  A risky way is sometimes starting the engine will provide enough
suction to get things started - but, naturally be prepared to shut it down
immediately if oil pressure does not come up.  If you do and it does that
points to an air leak in my opinion.  In my book Halomar is OK for the
coolant "O" rings as it more or less just holds them in place and does not
do much in the way of sealing.  I always use Ultragray or similar for oil
pan  but only use the gasket for the pickup mount.
