Oil in intake manifold and on intake valves

[Sprnt76]

Ok, so I have had this oil consumption problem for about 4months now so I decided to pull the head off to dig in a see what can be causing this problem. The head is off and the pistons and rings are great. I found some serious oily residue on the intake manifold ports as well as on the intake valves. There is about an ounce of oil when looking down the intake side if the head. Could this be bad valves, seals and or guides? Any help is much appreciated.

have you checked your PCV? you should be able to blow in one side and not in the other. if it is working correctly, is suspect the valve stem seals
