i have a boost leak where the tb and elbow meet .. since that area does not use a gasket .. how can i keep it from leaking? ive tried hylomar but that doesnt work .. and im sure the bolts keeping them together is on there tight enough

 

It is supposed to be sealed with an o-ring. If it's not there, that's your problem.

There were a few threads on this o-ring a while back.

If you need one, the stock one fits best and is available from Malloy Mazda (888-533-3400). Ask for Ray Crowe. They give discounts and ship quickly and free.

 

I recently replaced the same o-ring in my car. Easy to do. Takes about 5 minutes. The OEM o-ring "should" cost about $3. Expect to pay 5 times that

 

thanks didnt know that rubber ring could be replaced :P .. was scared i would have to replace the whole tb

 

If the oring is there (and it should be) it might be easier/cheaper to use gasket sealant. My car used to spit small amounts of oil from the TB/elbow junction, so I'm assuming I had an air leak here as well. The gasket sealant works great, just apply a even coat and crank it down.

Adam, you're not the only cheap dirty bastard

 

Is the o ring that orange/red rubber sealant thing? I took of the elbow a while back and threw that thing away. Now my idle is abit funky! So it's a must to have this o ring?

 

The Mazda o-ring is black. Someone may have used silicone-seal to try to seal instead...

 

but it won't change your idle.

 

I would just get the right o-ring, and do it right. It's not an expensive part.


Hey .......... I'm not dirty!!

 

The dealer priced the 0ring at $14 , wow . I get them from Nashville rubber and gasket for cheap. The hose supplier in Murfreesboro has given me a couple for free . I do not use sealer on them .Be sure the surfaces are not warped .
