Does anyone know if the o-ring seal that fits in the groove of the throttle body (where it mates with the stock intake duct flange, triangular in shape) is available? or is there a generic o-ring of the proper thickness and diameter that will fit? I searched for threads on this to no avail. It's for my '90 N/A.

 

I got a new TB o-ring from Mazda, p/n N326-13-W69 for all FC's.

 

You can probably bring the old one to a hydraulic shop and get a generic replacement. It's likely close enough to a standard size...

 

Thanks for the replies gentlemen. Until I obtain the correct o-ring I made a paper gasket to use in addition to my old o-ring. I don't like running lean for very long. The intake duct flange (plastic) tends to warp, and it doesn't help matters much when there are only 2 bolts holding a triangular object in place instead of 3. What were they thinking? of course it will warp lol.

 

Let me bring this "holy moly" old thread back to the light !

I just ordered this N326-13-W69 ... probably to late to ask this now but did anybody ever found a replacement for it? I mean I got it thru MMS cost like 11 bux + tax and I bought loads of other crap so shipping isn't a problem ... but like scrip7 said couple years ago this part has this 2 bolt holding a triangle design ... it will warp eventually cheaper replacement anybody ?

I dig my old one out couple days ago and is pretty much a "flat" piece of garbage for god knows how long ? it's probably leaking air left and right the whole time.

 

I was missing one,(misplaced it in a shuffle..lol) so I got out some gasket paper and traced the TB elbow.I made a small gasket for in between the TB and elbow and "voila"..I didn't need that gasket..cost me about 50 cents.
I eventually found the OEM gasket,so Now I have like 2 or 3 of those OEM gaskets hanging on a wall,just in case!

 

I was think about the same thing. But i never trust the paper gasket all that much...

Was think if anybody know the size of the o ring, should be able to find somethingbjust like it on the market

 

Um...... A small bead of rtv? In the groove over the ring.

 

At this point, one could probably run a bead of RTV in the groove, let it dry, then put the adapter on.

 

Just figured the old ring would make sure the groove doesn't have any air pockets for the rtv to miss and cause another leak.

 

$11 spendy? o-ring flattens out? give me a break. don't feel like dealing with this otherwise i probably would look into something.
