the crankcase vent hose is the hose that comes from the passenger valve cover to the top of the TB, right? if so, I rippied it doing the TB bypass. Whats the part number for it, and would autozone or kragens carry it?

 

GM p/n is 10128365 about 5 bux.. probably a dealer only item..
It is 1/2" hose, if that helps..
I just used 1/2" hose, and have the 'oil seperator' in the valve cover.. works fine..
