I got some new gaskets for my intake manifold because it has rtv on there. Which I do not like at all. My questions is which one goes where, there is an all metal one and a metal one sandwiched between some rubber material. I have included a pic to help you help me.

Thanks,

Hmm I dont know... My CFM+ came with two gaskets like the one on the left

 

Really, damn.

To me it makes sense to put the rubberized between the horn and the grid heater, then the metal one on bottom between grid heater and the plenum cover. But not sure.

 

I would say the one on the left is the one that would go on the bottom

 

That's my thought as well.

 

Yep

 

I would almost think the metal one goes on top, just on the physics of heat rising. The bottom one has the head as a heat sync, the top only the horn.

 

Really? I'm not sure I think the rubber one would go between the horn and the grid to give a better seal. But I really have no clue. They are from Cummins.

 

Not too sure to be honest myself. Let me look at my service manual to see if it says anything.

 

No rush, but if you get a chance I should would appreciate it.
