48 IDA Certification for California ?

OK,

As someone painfully aware of how this works re Webers and the CARB, here goes...

To pass, you NEED a closed PCV system. That means having a PCV valve from one valve cover to the crankcase. Second, to close the system, you need a vent running from the opposite valve cover to the intake over at least one of the Webers. This should be filtered air, as in theory, this air may be sucked into the crankcase.

What I have done is place set of aluminum spacers under one pair of carbs over (ie, 2 Weber 48s), and tapped each of these, and plumbed them to the PCV valve. I also have a dedicated air filter over one carb that has a hose from the second valve cover to provide the filtered air.

The setup is not complicated, and could largely be hidden if someone wanted to tap the individual intake runners. Thats not what I did, for reasons I don't want to get into on this forum.

Anyway, getting Webers through can be done, but you should also know exactly who is doing your inspection. DO NOT GO TO JUST ANY STATION!!!! Ask around, as some of the inspectors really have no clue as to what they are doing, but are not about to admit that to you. If they see something that is not ordinary...they're likely to just fail it, rather than find out if it is OK or not. Trust me on this.

If someone would like to know more about my set up, and possibly "borrow" it for reference purposes, please PM me.
