Any experience with these intake manifold gaskets?

AHarada · 12-14-2008, 03:43 AM

I made the mistake of re-using the stock metal intake manifold gaskets during my rebuild and I ended up with a fuel smell and issues with that. So I pulled the twins and both manifolds and the metal gasket from the LIM to the engine was wet and there was fuel getting past it.

Looking at new gaskets for the intake manifolds I came across these "thermal barrier" ones on ebay.

Does anyone have experience with them? They are cheaper than OEM, and are supposedly reusable, so if they seal well on their own, then I am sold.

Being thick like that might cause some installation and clearance problems. Measure first.

They'll probably compress and seal fine. But.........http://www.rx7club.com/showthread.ph...ghlight=intake
I'm not sure why/how fuel was getting past at that postion, but maybe your OEM gasket augmented with a little Gasket sealant would work just fine too.

I agree with the posts in the thread attached above. These are a common mod among Honda owners, but I really expect no performance advantage on my car. The only things I like about it are that they are reusable, and cheaper than OEM gaskets. I'm going to go ahead and try them out. I'm going to use loc-tite on the bolts and use a little more torque than the FSM specifies just because I really don't want to have to take the twins and LIM off again. If they lessen the amount of threads on the bolts that hold the LIM much, then I'll go ahead and get slightly longer bolts. I can't imagine any serious clearance problems but I will test them out. I'll post a review in a few weeks.

Do not exceed the OEM torque max values or you may be pulling broken fasteners.
That why they give the range.

I have used the UIM gaskets over again many times. Just apply a little silicone sealant or Hylomar sealant.

I ordered one for shits and giggles and I got it today.

The picture in the first post is very deceiving and the actual gasket is not that thick. I measured it to be 1.6mm with a micrometer. The stock gasket I measured right under 1 mm for reference.

I'm undecided still if I'll use the stock gasket with silicone or this. My stock gasket looks pretty beat up though so I might just throw this in.

Those gaskets suck ass they are garbage. Trust me.

If you want better seal between the lower and upper manifold a factory metal gasket or 2 factory paper one 2 is better than 1.

On that white gasket you have, after tightening down your bolts take a 1 thow feller gauge and check to see for a gap (leak). Most likely you will have one.

Hope that helps
