Oil catch cans -
Unfortunately, I did't think to snap a photo, but here's what I found when I took the JLT 2 oz capacity oil catch can off of my 3.7 for inspection. I had less than 2500 miles on the engine since installing it. The can was half full of oil. The car does not have forced induction and I don't drive the car hard. I was amazed at the amount of oil caught and thus not recirculated through the intake manifold, onto the backs of the intake valves and into the combustion chambers and spark plugs. If you have any engine - 4.0, 3.7, 4.6, 5.0 - and there is an oil catch can available , GET AND INSTALL ONE!
