Ill try and get a pic soon, but I need to someone to identify this part for me. If you look at your engine from the front of your car, (86-88N/A), and look where it says 13b fuel injection on the upper intake...look directly to the right of that, bolted on the side of there, its a round, blueish greenish vacuum run thing, about the size of a silver dollar and about 2" thick. I dont know what it is or what to call it, and I need a gasket for there. When I did my porting on my IM I took it off and the gasket cracked, and I need to get a new one and dont even know what that is. If you know , please tell me, and also where I can get that gasket. Should mazdatrix have it? Thanks alot.

Is there a reason you can't just put some RTV on the gasket surfaces? I've done this to my upper-to-lower intake manifold gasket many times with no ill effects.

If you use RTV, which is not recommended by Atkins on their rebuilts BTW, make sure you don't use any with Silicone. The Silicone will fry your 02 sensor.

I used RTV for my water pump with no bad effects. It works great.

Thanks for all the replies, I found a gasket. The reason that I didnt use rtv is becuase I just like to do things right, witht the right parts. I think how you work on a car is a reflection on you. Like if you were taking apart something and saw a bunch of silicone where there should be a gasket, you'd probably say "what kinda lazy dumbass put silicone here", or something like that. I just like to do things right. I dunno, Im weird.
