is Felpro gasket material suitable for an upper intake manifold?

[Chris2012]

Have to do the upper and lower, but not both right now. Just need to pop my plenum up and would like to avoid buying the whole set (80$). Is any of the material good for 1 - 6 months? I have some gray carboardy stuff from Pep Boys on hand, used it for a water pump a while back. Would that even suffice???

It should work just fine. Assuming you have a 60* motor where both the upper and lower are aluminum, then I don't see why it wouldn't work since the actual gaskets are just a paper/ fiber. Have fun cutting though!

the upper plenum gaskets are like $8.00 new for 3x00s

X2, just buy the plenum gaskets.

if i were really in a pinch, the make-a-gasket stuff will work for a 3x00 UIM.... it's not like they pass coolant through them or anything, just air, EGR, CCP and PCV draw-through.

For a 3.4 '01 Venture? Please tell me where. 8, 15, 25$, no problem. I've only seen them in sets. There's cheapo sets for 40-50$, even Felpro at the high end. Seems wrong to waste that much just when you have to do it again.

X3, that would totally suck to cut out, $8 well spent.

Actually there are coolant ducts on the 3.4 Ventures. And ... it seems Felpro actually does just supply upper gaskets. Durned why I didn't see them earlier.

$8.99 @oreillys. 19cutlass94 has a similar vintage 3400 in his cutlass. i used to have an 02 3400 crate in my 97 monte

the large-port UIM passes coolant through it? the LIM does, but i don't see where on the UIM.

the throttle body has its own little coolant connection, but it doesn't transfer any liquid to the UIM from what i've seen either?

[Chris2012]

Maybe I mistook bolt holes for coolant ducts. Someone on a different forum said DON'T use anything but the ready made (nylon and silicon?) gaskets. Sai d if I mussed it up I could get coolant in my crank case. which already happened on account of a cracked pcv boot. That yellow gook. Was making a horrible noise for about 2 days, not exactly sure why. I attributed it to faulty evaporation. I've learned and am learning more about cars in the last year then the prior 30.

Anyway I need to find a replacement coolant pipe (that goes under the plenum), or use hose.watcha think of that idea?

[Chris2012]

And a round of thanks to all who let me know about the cheaper options. Wasn't dreading cutting the stuff, the little bolt/coolant? holes had me a little concerned though. I was thinking a just score them out with a very sharp X-acto blade.

[Chris2012]

6$ at Advance. And I have plans for those 2$ I saved so don't ask!

 

I think I'm just going to cut the pipe off at the thermostat end and run hose. It already uses a small length to join the bypass pipe and this thing, so I can't see the problem.
