I have seen these on a site before and I would like to make my own. Anyone remember where this info is or happen to have it handy?

Take your BACV off and outline it on your material, then go from there..

exactlly. Or use the gasket if it comes off ok

Or, get a new gasket since your gonna need it anyway.

I knew I could do that. I would like to have the dimensions so I can build the part while my car is still functioning. Also so I can make a new gasket cause it is cheaper than buying a new one.



Anyone have the dimensions?

BACV removal takes about 10 minutes tops, with minimal coolant spilling. Two bolts. I've done many, not once has the gasket torn on me when removing it. If you are just putting the same one back on, then you don't need a new gasket if you take it off.



If you are worried about it, when you take the old one off, cut a new gasket out of a corn flakes box. It's just a tiny intake gasket.



Pull it off, trace it, put it back on, drive the car again while you make the blockoff for it.

What is the BACV?

Bypass Air Control Valve



Electronically controlled valve that lets air bypass the throttle plates depending on electrical load (for maintaining steady idle).

Mine has been blocked off. No air compressor either. What are the advantages?

Cleaner engine bay?



I can't figure out why people want to keep blocking them off. All it's going to do is hurt you idle speed, or make it inconsistant.



Unless you have a racecar and no electrical load (such as lights, wipers, etc.)

Sometimes their shot and its cheaper and easier to block them off.



Cars without A/C and P/S dont really need it anymore.

Yeah it is cheaper and simplier that is why I am doing it. I know it hurts idle speed and probably uses more gas, but it is a quick easy fix. I appreciate the input but I am looking for the dimensions of the plate. I know it is easy to take off, I have already tried to clean it. I would rather save myself the process of taking it on and off while I build the part.

anyone have a link for where you can get a BACV plate, that k2rd site does not work anymore and i haven't seen any bacv plates on mazdatrix.

thanks
