I'm wanting to buy some gasket material similar to what the Mazda OEM intake manifold gasket is made out of. You know that blue and white swirled pattern stuff that has a rubbery feel to the outside of it? I'm hoping to find something similar on a roll so that I can cut my own gaskets out of it for other parts of the car.

I have always used the paper or cork gasket material from Autozone, but it just isn't the same quality as the stuff that Mazda used to cut the intake manifold gaskets. The paper stuff doesn't cut very cleanly, and the cork seems to expand way out when you tighten it down.

Anybody know of a high performance roll of gasket material that I could buy in person or order online?

Here is what Summit Racing has to offer, but I'm not sure which one of these would really be the closest to the Mazda intake manifold gasket. I haven't even heard of some of these material types before. Anybody have the knowledge to tell me which of these would be the most like the Mazda IM gasket?

the only gasket material i've used is what u find at autozone and the like. but only used it for w/p and housing or t-stat tho. if i need an intake gasket, i'll just buy one.

 

i'm not sure what gaskets you are making, but um just order the factory ones?

 

I make my own intake gaskets out of the gray or dark gray/black roll material. Never had a problem with it.

 

i use carquest's dark gray material, don't have it handy so i don't know part number, but it's about 7 bucks a roll, and you can make about 6 intake gaskets with it.

Sure you can order the already cut ones, but i think that this other material is more durable and haven't had a problem with it, i've probably removed and installed this same gasket over 20 times with some coolant/fuel/oil spill on it and it hasn't even began to tear yet. i think its worth the extra bit of time and it saves you a bit of money in the long run.

it's close to the same feel, and look as the stock one, except it's all gray and more flexible.

 

damn i was going to say Autozone... haha i like to just use silicone adhesive sealant... who needs a gasket? never had any leaks... this is only for water pump and t stat not the intake gasket... also oil pan... no gasket needed...

 

Ever tried it with boost?

 

Considering vacuum readings can be more than 1 atmosphere to the negative, I would say a home made gasket would be good for at least 1 atmosphere, 14.7 psi, of boost.

 

If that were the case, the absolute manifold pressure would be less than zero, which is impossible. Highest vacuum I see is around 22-23 in. Hg, or ~11 PSI. Anyway, what I'm concerned about is gasoline seeping past the gasket over time, which obviously isn't as big an issue with an NA setup.

 

i have not personally tried it with boost, but was told by a couple of my local rotary buddies that informed me about it, that it's better suited for it. just for when i finally decided to go turbo.

i'm pretty sure he's using this material on this car:

NAPA is by far the best source of a good variety of gasket material. The brand escapes me but they had some very high heat material that only JEG's had. It had steel mesh between the ceramic layers.

Fel-Pro, I believe. I just bought some yesterday.

 

fel pro is pretty good quality stuff

 

If you want industrial quality stuff, visit this company: http://www.lamons.com/html/products.html

They supply all of the gaskets we use in the chemical plants where my dept does maintenance work. Not sure if they sell just the sheet material.

 

Okay. I admit I don't know how Hg relates to psi. With all the other rotorheads that have boosted their 12As. I can't say I've heard of any intake gasket failures due to boosting or fuel saturation. If that was the case, a good backfire through the carb could cause intake leaks and it doesn't.
