Hey guys, I just picked up my BAC valve gasket for my 90 GXL. The part # on there is N3b1-20-661. The color of this gasket is kinda orangish. It has 3 holes with a 1x1 square in the middle. The overall size is really small. I am just wondering if this is the right part of the BAC

 

sounds more like the ACV than BAC. the BAC only has one opening into the manifold and 2 bolts connecting it

 

It should have a square hole in the middle, two round hole on either side of the square hole for the bolts to go through, and a lil small dot sized hole for a vent I believe. It should be about 2x1"

 

What I described is the BPAV gasket, sorry.

 

This is almost accurate. I have my BAC in my hand. The center hole is 1/2" round, a small hole about 1/8" off to the side a bit, two screw holes on each long end, the whole thing should be abuot 2"x1" diamond/oval shaped.

Is that the right one

 

yeah, thats the BAC Valve gasket.

 

Sure looks like a square hole to me. I guess the BPAV and the BAC are the same thing.
