I did an experiment with a catch can on my 14 Silverado. It was a few ounces at best between changes and that truck would go through a couple of quarts. They definitely aren’t as critical as the internet would have you believe.
I hadnt seen much push for them on the chevys but mainly on the subarus, but they are an inline PCV situation and have 3 ports i beleive. I figured with the c10, any oil thats not re entering the intake manifold and mixing with fresh Air/Fuel must be good...? did you use one with a baffle, or just a vented canister? Maybe ill just run the hose down the back of the engine and dump it on the road like its 1955
, i just dont want it in my intake
