As I said, this was from GM, NOT from a dealer. Your suggestions are noted but when GM (NOT A DEALER) says there is that it is emission not powertrain I think they may know more than you do.
Even though you think I'm a dunce, try to keep in mind I'm trying to save YOU money.
As amazing as it seems, even the folks within the corporation are quite adept at disseminating incorrect information, and I was trying to point that out.
I'm not combative, I was a GM corporate warranty administrator.....end of that discussion.
The entire warranty system works off of labor operation numbers, labor ops for short.
There is no labor op for the valve we are discussing......this because the component is not considered serviceable.
As you found out, it only comes assembled into the intake manifold.
For the record, it is not an emission control part, it is for the purpose of enhancing low RPM torque output.
Doesn't matter, there is only one labor op for this part.......Operation number 4060450......manifold replacement.
Manifolds, regardless of the failure, are covered under powertrain (unless you hit it with a hammer)
If you can find someone wherever you are doing business to fire up the Global Connect system, go to service shortcuts, enter, select P&P Manuals/ Part & Service Publications, enter, select Parts & Accessories, enter, and then enter the labor op# 4060450 it will automatically go to Intake Manifold/ Powertrain.
Balls in your court, good luck,
