Yes it does, the air/oil separator sits in the valley of the engine. Oil that drops out just drains back into the engine. Probably works just as good as an aftermarket catch can, if not better due to it's prime location (water shouldn't condense there which creates other issues with catch cans).Has anyone researched this? Does this engine have basically a. Built in catch can?
Yeah I used to have one on my old 5.0, it condensed so much water that it was more dangerous than good. It really needs to be located in a hot spot where it can just condense the oil and let the water go through. I learned that the hard way haha. Hopefully this system performs well, so far I haven't seen any issues.LOL I was ahead of my time back the 1900's installing PCV catch cans on my old Chevys! It is surprising how much oily water accumulates.
