I have a ford f150 1992 with 64,000 miles on it. It is a 5 Liter
V8. Air cleaner is full of oil. Hose from Oil Filler seems to have too much
air flow to air cleaner and is blowing the oil up into the air cleaner from the valve cover.

How can this be? I noticed there is an air pump on this model
Is that the cause for this problem? Please help!!!

This is normally a PCV valve problem. Check that your PCV valve is operating properly and is tight in its rubber grommet. Crankcase Ventilation System (http://www1.autozone.com/servlet/UiBroker?ForwardPage=/az/cds/en_us/0900823d/80/0a/2c/dd/0900823d800a2cdd.jsp#hd1-1-2)

The air pump pumps air to the catylitic converter so it should not be involved.

PVC Valve O.K. Gromet O.K. There is a strong positive air flow
coming out of this hose. It Will Blow up a quart of oil in about
150 miles.I have never felt this much air come out of an engine.
It is a steady strong air flow. Any Ideas?

Something is amiss. The hose attached to the pcv valve should supply a constant source of vacuum. Check the hose routing against the vacuum hose diagram in the engine compartment.

The pcv valve is O.K. and there is vacume. Air pressure is comming out
of the engine on the other side.On the other side of the engine or the
other valve cover where you put the oil in, there is a hose that connects under the filler cap and goes to the air cleaner box. this hose is
suppling a lot of air pressure to the air filter box and is blowing oil into the box and pluggs up the air filter. If I disconnect this hose from the
filter box it has a lot of + air pressure and smokes when the engine
is warmed up. I noticed It was a week ago I changed my oil and it is
already brown,oil pressure was low, Oil is now very thin. I am afraid that
I may have a cracked head or gasket sending hot gasses into the engine.
What do you think.

Something is pressurizing the crankcase. Do a compression check.

Sounds like you have a valve not sitting right causing oil to drain into cylinder, when started up the pistons will push the oil back up through the hoses into air filter and burn your oil up at the same time causing it to smoke. I would also do a compression check first just to be sure rings aren't wore out. Good luck!
