Checking things in the engine bay after an oil change today and noticed a bit of oil "blow by" on the hose that goes from the valve cover to the intake. Maybe at 24 psi I need a 2nd catch can.

Surprised with the clamp that oil would seep out of the hose. I also thought you already had a bypass on the clean side, guess not.

Maybe the clamp isnt good enough.
Will be installing the occ soon. Just gotta make a bracket for it to fasten it to the battery tie down bolt.
If I understand it correctly, it goes from the valve cover to "in" and then "out" to intake...right?

That's a good question. The normal air flow is air tube to VC, but when pressure builds inside the engine the flow is reversed, VC to air tube.
