True but it can be hard to distinguish white from "blue" to the untrained eye.

Now the Yukon is not smoking at all during start up. I have not replaced anything to remedy the problem. Any thoughts on why it would stop on it’s own?

Maybe the little orifice in the pipe coming off the valve cover is plugged. Start the engine and pull the oil fill cap and see if there’s any pressure or fumes coming out. Shouldn’t be when idling and pulling vacuum on PCV in drivers side valve cover.
I would still install a catch can but definitely find out if the hole isn’t clogged. I had to blow compressed air thru one one on my buddies 2010 Hoe because his valve cover started leaking and there was pressure when I pulled the oil fill cap.
I’d start there.

Have that part #? My 05 is doing this but I’m thinking it’s the valve seals.. I might try the valve cover though.
