I am getting quite a bit of oil in my air breather housing. Anyone know what would cause this?

Check your pcv valve and the hose to make sure you are getting good vacuum. The line where it connects to the intake manifold might be coked up.

Likely worn piston rings, not uncommon with these. Also, isn't there supposed to be a small filter in-line with that hose from PCV to air cleaner, like Crankcase air filter Fram BA7100? https://www.amazon.com/FRAM-BA7100-Crankcase-Breather-Filter/dp/B000C31J50 http://www.rockauto.com/en/parts/fram,BA7100,crankcase+breather+element,4932
