It's obvious that I don't know my way around a 6.2 because I don't even know what those valves are, lol. But those rubber elbows, what size are those? They look like they might be the correct part for TPI breather tubes. If so, those alone might be worth the price.

It's the crankcase ventilation for a diesel. Since there's no vacuum it can be a little more challenging to control than on a gasser.

so youre saying you cant just put a breather on both valve covers and pretend that does something? This is madness!
lol but we have all seen that on a gas engine..

Hell, my sbc had two pcv valves in both covers with one being hooked up and the other not.

I'm sure GM was facing some regulation or they'd just use a road-draft tube.

To be fair especially in a diesel engine having PCV even if convoluted probably helped oil intervals/longevitiy becuase I can just see a diesel with a road draft tube and now my eyes are full of sludge lol
