Redesigned V6 intake manifold gaskets

#1

I asked this question on another thread but probably
should have started a new one. Family have a 95 Century
3100 that is ready for its second intake gasket job, the first
one was eight years and 40k mi ago. They are trying to decide
between taking it to an independent garage or back to the dealer.
Are the current gaskets from GM similar to the Fel Pro
Permadry (metal frame) or is GM still using the redesigned
plastic frame gaskets with the metal buttons in them? This
would be for a 95 3100 VIN M.

GM has the newest gaskets and you should use the updated bolts and torquing
procedure. I believe FelPro also is at the same point with this issue.

If you can get metal frame gaskets from FelPro, then use them.
We are still being handed the plastic frame with the metal
buttons for this engine. GM has changed over to metal frame
gaskets for the 3800 v-6, and the Vortec v-6 and v-8. I
suspect that GM must have a bunch of those plastic
frame gaskets in their warehouses that they need to get rid
of first.

The dealer is the only place for warranty work, but they are usually a hefty
premium for normal repairs. If you have a good independent shop, stick with
them.

We have and 04 Suburban with V8 Vortec. Dose this have the plastic or
metal frame, and should we be worried about gasket failure. Thanks.

As far as I am aware, all V8 Vortec engines run dry intake manifolds, no
coolant passages except for 3/8 hoses to the throttle body.

The engine is 5.3L flex fuel.

Kevin
That would be good news about the dry manifold. Is there any way to
know just buy looking at the motor.

Thanks

Has a coolant crossover pipe running between the two cylinder heads at the
front.
