So theres coolant on my intake manifold
 
Yeah i know i should know more about this but i dont. Ive got coolant sitting on my intake mani right next to the engine. Im pretty sure its coolant cuz of the color. I spilled some gas there from working on my carb so i cant smell it to tell.

What does this mean when you have coolant sitting there?

just have to replace the coolant o-rings between the engine and the intake manifold, or just plug the holes up. I know some people use some sealer and quarters, or freeze plugs or whatever.

Time for some O rings and a new gasket. Don't remove the carb. It's actually easier to leave it on the manifold and remove them together.

Even if you plug the passages with freeze plugs or go the ghetto route and use quarters and some sealer, replace the o-rings. If your plug fails and you don't have o-rings, you'll loose coolant real quick. The o-rings are cheap. You can hold them in place while you replace the gasket with a dab of hylomar.

I've gotten away with using nothing but friction from the rubber against the aluminum. Once they were fully seated in the recess, they didn't fall out or move. :)

I don't have o-rings in the manifold currently. I hardly loose any coolant.

Replace the o-rings. They are like 50 cents each. Probably would only take an hour to do the job too.

Make sure you remove ALL of the old gasket/ sealer from the manifold and rotor housing before bolting the intake/carb assembly back on. The stuff gets so rock hard from age that it is hard to tell where the gasket material ends and the metal begins. There can be a significant build up on the left and right ends of the housing. I didn't get it all off of mine and bent/cracked the intake manifold mounting flange. I discovered this after putting the engine completely back together (in the car) and finding that the water jacket seals leaked worse than before. Luckily, the cracks in the manifold flange did not go through to the passages and the slight bend came out after the gasket build-up was removed and the assembly was bolted back on. I'd use a small amount of Permatex to hold the o-rings in place during installation. I tried them dry the first time and had one pop out while trying to re-mount the intake. Take it from me, you don't want a seal to become dislodged during re-assembly. If you are performing the work under the hood - it could happen and you'll NEVER see it. Better safe than sorry. Also, water test the system immediately after bolting the intake back on - BEFORE you reassemble the rest of the engine. Good luck!

yea, making sure all the old gasket is gone is very important, mine still has a vaccum leak because I didn't get it all, but I have no time to fix it. ugh, at least its an easy job, 4 hours at most, and thats with removing the carb

RotaryRyan 07-22-04 02:38 PM

So i need new orings and gasket, right?

Anyone got a link to who sells the gasket. And are they just universal o-rings?(can you guys tell ive never done intake manifold work:D)

cdrad51 07-22-04 02:46 PM

mazdatrix.com

Junia 07-22-04 02:47 PM

I got mine from victoria british.

RotaryRyan 07-22-04 03:17 PM

Okay, i found the gasket and orings in my VB catalog. Thanks guys

louved_gen1 07-22-04 05:45 PM

that should do it

bizarro 07-22-04 07:38 PM

make sure you get gasket sealant with that too

msmcgill 07-22-04 08:36 PM

You can get o-rings and a gasket from RX7world.com, too. Cheaper prices - unless you get nailed by the fixed shipping charges and/or sales tax. Mazdatrix.com ships faster.

RotaryRyan 07-22-04 08:47 PM

How long does vb usually take to ship?

82transam 07-22-04 10:11 PM

Usually takes a week or two to get stuff from VB. And bizarro is right, some high tack gasket sealer will help.

RotaryRyan 07-22-04 11:41 PM

Alright guys i think i have it all figured out. Thanks :)
