Just changed upper and lower intake gaskets on a Lumina
Just finished, and my toes are cold. My heater ran out of kerosene, I need to watch that closer. Took a lot of pictures so I will do a write up on doing uppers on a L36. I'll post up some pictures in a bit.

I used the black that comes with the gaskets. I had her pick up the parts. Shame she got the plastic LIM gaskets. But she will be fine for a long time.

Dan (and other MasterMinds), if you get a chance please take a look at this gasket tech tip article and share your thoughts:

First is was off with the fuel rails.
After the fuel rails and injectors were all out of the way I removed the throttle body.
The UIM has 8mm bolts,
had to take the alternator and move it out of the way.
Because someone decided it would be fun to hide a bolt under it.
And off it came.
I convinced her it'* worth doing the LIM gaskets as well.
Let'* hide 2 bolts inside the LIM.
And it'* all off.
No mater how hard you try, coolant still gets in to the lifter valley. A prime reason why I like green.
All cleaned up and going back together.

Looks good Dan. We should probably mention the different sized EGR stovepipes and point out the common failure point in the UIM where the stovepipe passes through. I like to emphasize the importance of step torquing the UIM bolts to their 89in lbs total torque. Not stepping can sometimes result in the ears breaking off the new UIM.
