I think this was the GM number, but it's showing discontinued. Says it's a PCV fitting and tube.

12597772

 

As for the nipple on top of the intake, I believe you can use the nipple from the older style truck intakes, I'm not sure sure on that, but I will double check to confirm that.

 

i thought that, but i tried taking mine off my old intake i had laying around and it wouldnt budge. It seems to be lower profile as well (the base on the older intake)

 

Still looking for help on this. Dealer tells me they cant get the part and it comes whole with the intake, going to try a different dealer today.

I can always do as Atomic said and tap the hole and put a plug or a fitting, but theres only a ridge of maybe 1/8" in the hole that would be tapped and i dont know if i feel comfortable with a piece of metal tapped into that, if it ripped through that little ridge it would be straight into a valve.

 

JB weld on the cap threads, it will not ever go anywhere.

 

ya i suppose that could work. I guess no one will ever see it anyway.

 

There is ways to do things that arnt necc the best way, but if done correct still looks nice and works as it should.

 

case in point lol..ya that should work just fine.
