If the upper intake itself is at fault, is it possible that it will seep coolant around the gasket mating surface? Or could this just be a bad gasket. I want to fix my coolant leak, but I only want to do it once. The shop class as my school said it'* probably a gasket and that it would take them 12-13 hours to replace (All Data says it should take 2!) I'm gonna do it myself, but I just wanted their opinion. Now I want yours because they obviously are incompetent.

Yeah if you only want to do it once replace it all while it is all taken apart.

ha ha 12-13 hours? who do they think they are a GM dealership?

hahahaha

HA
you are correct it should take about two hrs to change just the upper gasket.
Now if your like me and you do the upper and lowers along with the plastic coolant
elbow and clean everything the way it should be, its around 5 or 6 hrs.
Beleive me the cleaning is the most cumbersome part of this process. Including
soaking the injectors while they are out.

Hey glorkar, just changed the upper intake. Took about 3.5 hours in the rain, holding a flashlight, (short on resources and pit crew). Good luck and change the intake while you're at it. $150 aftermarket (napa). 10mm, 8mm sockets and a screwstick and you're in business, then sell it and stick to you're Ford project.

I wouldn't sell her. She has too much life left. Besides, the bonne will be my daily driver. The stang will be my fun car (the gp is really the fiances)

$150 for the upper intake? I'll be needing one sometime but is this one just as good as the OEM one or is it not as strong?

Get the new metal series III intake for a lot less.
All you need is an adapter for the throttle body.

And where might I get an intake for a series III and TB adapter?

GM Parts Direct. 89017283, I think that'* the part no. for the UIM. Can't remember who makes the TB adapter, might be ZZP.

It'* just bad engineering/design. The reason why the UIM starts leaking is the EGR stovepipe heats up the plastic manifold and causes it to warp, which then causes a leak of coolant into the upper intake. So technically if the EGR pipe was not there, there would never be an issue with it.
