FYI - Ray sells a gasket rebuild kit that includes these manifold gaskets as well as turbo to block, manifold to DP etc etc for $120.

I personally don't like to experiment with **** that *might* work. i don't like to do things twice. Do it right the first time and you can spend more time driving your car than fixing things twice

 

My sealing comment was a directly reply to this comment.

They "look like they would seal better".

lmao, you guys kill me. I never stated that these would work. This is all in theory. Thats why i am willing to be a guinea pig and test them on my ride. and if they work.. they work. end of story. If they dont work i will be sure to let you know why they failed. And no one ever said go out and buy these gasket's right now...


"I don't know how you can say that something would seal better than the OEM (metal) gasket. As much as people bitch about engine replacements not a lot of FDs should have the original paper gasket."


And Jeff, Your comment made it sound like i said "yes these will seal better" I just said they look like the would. The reason behind me saying that was, when you feel the gasket it has a "mushy" type property to it, so when you torque down the UIM nuts it would seat even across the surface.

I can understand people being skeptical about this gasket set, but before you all start flaming it... Let me atleast test them and do a writeup on my experience with them. One person posted in this thread saying they had them on their vehical for over 3K mile's with no problem's. Does that mean they are good? Not at all... But it j"ust seems to me like alot of people are jumping the gun on them. MY personaly opinion on the gasket's is that i paid 20 something bucks for them,I make that in a hour. So if they dont work. oh well.

 

Would you like a cookie? Seriously, you dont impress me. So GTFO my thread


the only one being retarded here is you, Do you think just because you know how to polish an engine you are better then everyone else? Thats how you come across. Who gives a flying terd if this dosent work? no one.. you know why? Because I bought them. not you. ME. Thats why i am doing a writeup on them. jesus.

 

Good info on Teflon:

It must be pretty frustrating when you make a mistake and everyone points it out repeatedly. It makes no sense to try out some random ebay gasket to test it out for everyone. This car is about done we don't need people doing R&D on ebay parts especially when they are the same price as the mazda ones which are perfect because they are made for the ******* car its amazing!! If I were you I'd cut your losses right now and order the mazda gaskets so you don't have to do the job twice. I hear removing the lim on twins is a bitch, do you realize you have to take out the twins first!? And I know I come off as an ******* on the forum but its because there aren't many people on here that I agree with. Ive had to do my whole project by myself and its pretty annoying to always be giving out correct info and then recieving no help or seeing dumb **** like this. The polishing thing takes a lot of practice and I think you lack the discipline to learn something on your own so shut the **** up. I've even shared the quick steps to help everyone so what else do you want from me? Polishing isnt a huge deal compared to the rest of the work I did on my car its like 1/30th of my total project

 

haha. Pointing out my mistake's? I see no mistake's with trying out a potentialy usefull gasket. Anyhow, you act like you are the know it all mazda RX7 guy. Have you actually provided any usefull information in this thread? OR ANY thread for that matter. Just about every single post i see posted by your account comes off like a "condescending hey everyone look at me i know what im talking about attitude". How about for once you try and provide usefull and relevent information for once. So how about YOU shut the **** up and grow up. Polishing is more time consuming then hard kid. No where in ANY of my post's did i tell ANYONE to run and get these because they are awesome. I simply stated i was going to install them and see how it works. And seeing how my 7 is not my DD anymore i have all the time and the world to tear it down and put it back together. So keep polishing brother, cause we all know that make's your car faster.


You have some ***** to come into a thread where someone is testing a peice of hardware and talk ****. You notice how the more mature members here posted a very professional and intelligent argument to why they feel the gasket will not work correctly? Oh wait, im sorry. You did'nt (obviously). So next time you wanna step up and run them fat lips of yours.... dont.

 

you are very right. Ill let you know what happens when i try and line everything up.

Good point though!

 

I worry that Teflon won't hold up. According to a couple of sources, the top working temperature for PTFE Teflon is about 500-600F. Being just a couple inches away from the turbos, I would think the lower part of the LIM gasket could cook and leak. Maybe, maybe not, but I wouldn't chance it.

Dave

 

i tend to agree with you on that. I think i might just take a torch and burn the LIM gasket to see what temp it melts at. If i attach a high temp sensor to it and apply gradual amounts of heat, do you think this would work?

 

Nope, not really. It will melt around 700F IIRC from the sources I read. Applying gradual amounts of heat is hard to do with a torch that burns at a couple thousand degrees. Testing it would be done using an oven of some sort, and don't use a kitchen oven since the offgassing / smoke might be nasty.

Teflon is great in high pressure/temp steam applications, but still I don't know. At the UIM it should work fine - I'd test it there for a while and see if your UIM temps go down.

But still, the paper gasket in the early stockers is probably only good to a few hundred F, and the rubber coating on the metal gasket can't be for much more. So it might work out A-OK based on those comparisons.

Dave

 

Wow, lots of h8 and very little <3 on this thread...

Just let him test it out, its his car, his money, his time. If it works out well, then we'll all know there's another option out there instead of OEM. If it doesn't, we'll all know what not to buy.

And hell, what if it works as advertised?

 

Honestly, *who cares?* We are talking about gaskets here. Not apex seals, not oil control o-rings, not oil metering pump lines, nothing very substantial.

What exactly is to be gained here? better sealing? Best case scenario you can save a couple of bucks. Personally, I don't take shortcuts on the car. You run into a case of a snowball rolling downhill.

Nothing personal rx7wishing, but I just don't see the point.

 

The block side of the lower gasket will be temp regulated by the coolant. The stock heat shield should minimize radiant heating of the lower IM, which will spread and radiate any heat it does pick up after shutdown. I doubt that gasket will see anything near 300F.

I would at least use lock washers, should there be any creep in the teflon, and bolt preload loss. Longer studs with steel spacers would be better, bellevilles best.

 

Nothing personal taken bro. I have no problem with critisim. Especialy when you talk to the person like an adult.

The whole point behind this was an alternative IF someone wanted to use them. Also, If someone wanted to know if they were worth it or not. I did'nt buy these for an end all solution to UIM and LIM Gaskets. Was purchased to see how good or bad they would perform. Last thing i wanted to test on them is how well the UIM gasket will take being taken on and off. Seeing how im always under the UIM.

 

very brave of you to do a trial and error type experiment on your own car......

i meant that as a compliment.

good luck

 

How did they turn out?

Did the ports match?

Do they make the gaskets for TII's (they are still paper)? I would be interested in how they worked as the TII have coolant through the LIM. I would be willing to try with out the O-rings since it's not a huge job

This summer I'll prolly get a set. People make it seem like it's a big deal. It's only 20 bucks and won't cause your engine to explode

I have alot of ebay knock offs in my car (4-5). I also have some very expensive items.

I'll take a knock off that does it's job any day over OEM or Aftermarket.

 

I just don't get it. I paid, IIRC, around $15 to $20 for a LIM gasket from Mazdaformance. It's metal and is guaranteed to work. You can buy one on Ebay for $20 that is not proven and has a good chance of failing. Changing the LIM gasket is a *huge* pain in the ***. What's the point?

 

Finaly got around to replacing the UIM gasket... Before i replaced the gasket i suspected i had a vaccum leak somewhere. i was pulling around 15psi=14 psi of vaccum, and my idle was "popping" alot. Seeing how i dont feel like typing to much im gonna give you the short version.


Replaced OEM Metal gasket with Ebay Gasket (UIM only). No silcone sealer used. Idle now sits back at 16-17 psi. Idle is as smooth as glass. 100 miles on it so far.. 1 155 mph run and everything is still working. Im not saying the gasket is better then OEM, but the OEM was def leaking ( prolly from the multiple times i pulled the UIM off and reused it :p ) I am pulling it off again this weekend if its nice to replace my check valves with Dale Clarks Vistons. Well see how the condition of it is when i take it off.

 

Rx7wishing

Are you the guy i emailed this weekend about the gaskets fitting properly or not.

I am thinking of buying this gasket set for my rx-7 soon. I used the Hondata heatshield white phenolic gaskets on some of the boosted and N/A Honda/Acuras that I build and they are almost twice as thick as these look from the pictures. I believe that these things will work just fine and withstand the LIM heat just fine as long as they were made out of the same material that hondata uses for theirs.


Here's one car I built that successfully uses the Hondata gasket. It doesn't leak, even with a big S/C on the intake manifold ( of course the manifold has a bracket though ).


http://www.importlounge.com/forum/in...dpost&p=288530

I wonder if they will drop intake temps just enough to add a little more detonation protectiom, amongst the other items used to cool the pressure charge.

Heck, maybe it can help keep a few more degrees of heat out of the fuel rails hiding under the UIM also.

 

I am interested to hear how they turn out, too. Thanks for trying them and reporting your results.

-Max

 

They ARE twice as thick as the OEM ones. i had absolutly ZERO fitment issues with them being thicker.

I haveny checked my email in ages ( the one i registered with).

EDIT: Yes you did email. I guess i answered your questions here

 

Just an update: Had them on the car for over 4 months now. No vaccum leaks at all. I have removed the UIM several times tracking down boost issues. After all of this the gaskget sealed and resealed as advertsed in ebay auction. 8K miles and no problems yet!

 

Thanks.
