Intake Manifold Gasket

[booosting92tsi]

I'm putting in a new Intake Manifold Gasket in my 1g dsm, my old one was cracked and leaking big time.

What's the proper torque specs that i need to bolt this down to? Is it recommended that i put RTV sealant on it? do i need to reinstall the Intake Manifold bracket back on, or can i leave it out with no problems?

is there aftermarket gaskets that is recommended? or should i just go to a mitsubishi dealer a.k.a. SATAN? HOW MUCH DO THEY GO FOR?

Sounds like somebody needs a chilton....................


WALMART TIME!

If you not going help, please try not to respond to the questions, being a smart ass isn't going to help him finish his project. If im reading my DSM manual correctly, the inside bolts are 15-20nm or 11-14ft lbs so work from the inside out in a crisscross pattern. There is a bolt that goes into the Ignition power transistor unit connected to the manifold and one that connects to the engine, those two bolts are 10-12nm or 7-9ft lbs (same for the fuel rail and pressure regulator parts). It is recommended that your reinstall the manifold brace bracket and the throttle body stay bracket. Make sure you use all new gaskets. As far as performance gaskets go im not too sure, but I know there are some copper ones out there so search around. I hope this helps, good luck with your project.

HONDATA makes one now for DSM's

it works as an insulator from radiant heat of the head and a very good gasket aswell. crankbender did a write up of this not too long ago.

Yea they do ... but $60 for an intake manifold gasket?!? The stocker works fine. There is a paper gasket and a copper gasket I believe. Last time I used a paper one I put a thin coat of rtv on both sides. Copper I used copper spray on both sides. Good luck.

$60 isnt as bad as you think. Its not just a gasket, it is a phenolic space which insulates the engine heat from the intake manifold. Im not sure what the real world gains are with it but theoretically, it should help keep the intake charge slightly cooler.

I personally would go to satan and buy the factory intake gasket. They are steel instead of paper so it would be less likely to blow in the future. I have lucked out with the paper gasket I had on my car but this time, while I have it apart, I will install the factory gasket. Im just not sure how long the paper gasket will hold on my car at 25+psi of boost from my 60-1.

if i go to satan, and buy a metal gasket, how much is it? can i put rtv on the metal one?

Forget those stupid Phenolic gaskets, they do squat. I have pulled more of them off Honda's then I know what to do with. In the last year I would say 4 Honda guys come in with their Idle going up and down like a vaccum leak. Well guess what it was. That stupid gasket. The potential for 1HP with the downside of them sucking ass just isn't worth it.

Secondly, you don't need to even use a gasket, just use RTV for the gasket and don't even run the metal one unless you really want to. I havn't run an intake manifold gasket for 3 years and have re-re'd the mani a few times with no problems. Just slap the shit on bolt it down hand tight and enjoy.

can you leave off the IM bracket? is it dangerous to leave it outta there? what temp rtv do u recomend??

Just to be fair here the hondata gaskets are not hard phenolic so should not have the same sealing problems. The material is closer to teflon.

That said I have before and still believe that you should silicone the gasket in just to make sure you don't get a leak. Make sure you use a high temp, 700 degree should do it.

IMHO I would rather spend 60 bucks once on a gasket and never have to buy another again. The gasket will not only help prevent conductive heat transfer to the manifold but it will help in absorbing shock on the intake system (isc, tb, etc). Not to mention you will never have to worry about the intake manni damaging the head sealing surface while you are putting things on and off.

All in all I don't see a reason not to use a spacer unless the price is an issue. Now you are not going to see incredible power gains but you will have the potential to have power gains. As stated before in a forced induction engine the gain on the intake from a lower temp is not only caused by the density increase as on a NA car. With a reduction in intake temps you move farther away from detonation which will let you run that little bit more boost. Do 5 things like the gasket and you could gain as much as 3-5% in power. Yes this is only 1% or so for the gasket but if you look at it as 20-30 bucks per horsepower that isn't that expensive.

I wasnt trying to be a smartass. I am stating how much a beatiful thing a chilton is. It's a mans best friend and it is well worth it. IF your working on your car alot, let alone own a dsm, it's not a bad investment.
