I received the Ebay UIM and LIM gasket's today via USPS. First impression was they looked hella cheap.. lol go figure. But after opening the package and feeling the texture of them they do "seem" like they would seal very well. They are very durable as far as texture goes and they dont feel cheap at all. Ill do a more detailed writeup on them once i get it installed (maybe this weekend).

So far they feel durable,strong and definetly look like they would seal better then the paper/metal gasket. BUT that has yet to be determind. I'll get back to you guys on that.

 

what kind of material are they? they look sort of plastic or ceramic... I would be concerned that a cheap gasket would warp from the excessive heat of a rotory. why did you decied to stray from the oem gaskets?

 

How much did they set you back if you don't mind me asking? Now if they only made one for the turbo to block gasket.

 

i hope you bought these cause you have a leak not to lower intake temps and gain hp like on their auction.

 

I have these also.They are plastic they sealed well for me I have had them on for about 3000 miles now and doing very well.

 

arent they cheap from mazda? gimme a break man get the real deal or just leave it

 

i got thes for 20 bucks. whats your definition of the real deal? something mazda makes? you give me a break. why not try something that may be better?

 

i have a leak at my LIM. i also am converting to NS. so i thought now is a good time to use them

 

hey im in va beach and have a set of block of plate, also a manifold of a n/s car with no cracks and a bunch of other stuff since im parting out teh drivetrain. let me know if ya need anything, ill give you a good price. Mike

 

Or, why try something that may be worse ?

That LIM sucks to R&R, so hopefully those suckers don't give you any problems.

 

i do i do! i pmed you

 

we will find out

 

If they made one, it would melt. The one on the LIM might not handle the heat well either.

I spotted these a while back while preparing to remove my UIM for a sensor replacement. I decided against them, but I'll be watching this thread. Hopefully they'll work out, but if they don't, you'll probably save someone else some $$ and alot of headache.
Oh, and I gotta ask RXWishing, who IS that in your avatar and did it do much damage when you ran 'it' over? Looks like a morgue shot from work.

 

Thats my plan.. if it dosent work out. You guys will be the second ones to know about it (AAA will be first).

Thats my mom!

 

When you get the old ones out just let your dog chew on both of em. See which one lasts longer! He/she? looks awfullly interested!! LOL! Just kidding waiting for a good report on them...

 

 

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.

I've never seen or heard of anyone complaining about the stock metal gasket leaking.

 

I just blew my stock cardboard LIM gasket. The engine was last rebuilt in 96-97, just before Mazda went to the silicone/metal ones. D'oh!

The cost for a new LIM gasket was about $20. That's cheap.

 

Looks like an expanded teflon type sheet gasket. Does it float?

Thinner than the true 1/2 to 3/8 inch phenolic spacers used to keep the intake manifold cooler. But should help a bit. Use an indoor/outdoor temp sensor to get some bef/aft numbers. Would also help to bypass TB heater.

 

Was that directed towards me? I never stated that it would seal better. I said it looked like it would seal better. But, for the sake of argument. A seal is a seal is a seal. If car holds vaccum and boost, and i can reuse it mutliple times without problem.... Then im happy.

 

What the hell kind of avatar is that anyway, wishy?

 

yea just get the stock ones and quit being retarded
you dont buy ebay brand stuff its not like we dont have enough great companies making parts for the 7 still
do you want me to post my mods i see no ebay ****

 

Those look like teflon or nylon - the LIM gasket is probably going to melt/warp/disintegrate, IMHO

 

I don't know what the gaskets are made of but if it's Teflon it certainly won't melt or warp. Teflon is tough stuff and very heat resistant.

I don't know if it's a problem or not but with those thicker gaskets the LIM is going to move away from the block and the UIM will be higher. The UIM probably will no longer match up to it's bracket just in front of the throttle body. The pressure tank mounting holes may not align either.
