Changing intake manifold gaskets

[eternal21]

Since I've had it, the idle sometimes idles @ 2500 rpms. It'll do it for a few days then stop. After rooting around, I figured it might be the intake manifold gaskets. Finally got it apart, and it appears that the lower manifold gaskets, which I've read are usually a hard plastic, are actually a rubber gasket. Looking at all my service records, the gaskets were never replaced. Interesting to say the least. I'll see if I can get some pics later tonight.

I've replaced mine before - I believe their phenolic sandwiched betwen thin metal (aluminum?).

You are correct, sir. For some reason, it looked surprisingly like rubber. But they're done.

Good deal. Please don't over torque this assembly the correct pressure is 13 lbs. Yes! 13lbs. Not the 18lbs in the mannual.

Is there a sequence to tightening them?

Yes there is. It's in the manual but you can't go too far wrong if you do it radially.
