Ok, I had some free time today while working on another vehicle so I did some digging. Hopefully these details will help anyone else with this engine. It is not setup like the typical tahoe 5.3. Why? I have no idea but we bought it from a chevrolet dealership used. I will be documenting all of my statements with pictures.
1. The ports on my valve covers ARE NOT PCV valves. They are ports and they vent directly into the airbox resonator. There is a very small amount of oil that has collected in the elbow of the fitting bit I examined the airbox and there is no oily mist making it anywhere near the throttle body. Look at the pictures and you will see the hose routing. The drivers side does not terminate into the intake manifold like it would if it were a pcv valve. On the contrary, it is a pressed in metal fitting. No valve action to it, straight pass through the valve cover.
2. My PCV valve is Located under and slightly to the right of my throttle body. The original line for this followed the drivers side fuel rail ant terminated into a fitting in the drivers side intake manifold. This termination point is the exact same as the models that have the PCV valves in the driver side valve cover. Here are some pictures of the Actual PCV and its termination point on my LT.
Final thoughts and questions I asked myself:
I ordered the incorrect setup for my application if I want to capture all of the inputs. The correct catch can setup would have 3 inputs and 3 outputs or 2 inputs and 2 outputs with tee fittings for the air box ins and outs.
Am I concerned? Not really...the amount of oily mist passing through the valve covers into the airbox is small to none. As stated above, a VERY SMALL amount collects in the elbow fittings and none has made it through to the throttle body. For proof look at the butterfly on my throttle body. The truck has 76000 miles and this has never been cleaned. If there was oil making it to there, it would certainly show and it would need to be pretty heavy for me to care.
Verdict: Im keeping it the way it is setup. It is catching oil, it is doing its job.
I sincerely hope that this helps someone in the future. Thank you all for your help.
