No gasket that could be cuasing the problem? My hose leading to the breather is fine but I did use an after market pcv vaulve. This thing blows my mind!

 

Aftermarket PCV valves have the tendency to be looser tolerances than the factory ones, allowing more oil through and into the intake manifold. It's at least something to look into. The factory ones are like 7 or 8 bucks.

 

I agree that a quart per thousand miles is excessive, especially if it comes on quickly. I have 90K and change my oil before it's down a quart, between 5000 and 6000 miles. Chrysler states that 1 quart/2000 miles for the first 50,000 miles is acceptible and then it is acceptible to got to s**t, quart/750 miles. Below is the current TSB form Jeep, but it is the same across all product lines
