No idea on procedure, but yes from what I have read the gaskets are poor quality and should be done while you have it torn down that far.

There are 8 bolts (I believe) that bolt the lower intake to block. You simply remove those, then work the lower intake loose from the gaskets. Pay attention to the coolant by pass elbow as you work the lower intake loose. They can snap, leaving a chunk of plastic in the port that it fits into (then you have to chip it out). Check your Chilton'* manual for a complete procedure and pictures.

And yes, you're simply going to change the gaskets. I recommend using the Fel Pros.

Good luck!!

lowers are held in with 11 or 12 bolts. buy the gm gaskets, as they've upgraded the lowers to a much more robust design. as stated above, the upper intake should come with the upper intake gaskets and TB gasket...

and i wouldn't even think about *not* doing the lowers... they are usually as bad or worse than the upper.

in any event, the first time I did a failed upper intake (i've helped a buncha people take their dead ones out), you couldn't see the failure at first. when we started poking around, we found an extremely weak point in the composite that gave way when we touched it too hard... so I think he had been dealing with porosity... coolant seeping through weak areas. it looks like the composite is really quite worn around where your egr stovepipe sits.... and that'* how it happens. it shouldn't be rust colored in there...

well my mom just called me a few minutes ago, this morning my dad took in the upper to show to our family mechanic to get a little advice...apparently he thinks you guys arent real people or something although he did use the write up in techinfo to remove the upper...so go figure. but anyway my mom gave me strict orders not to order any parts, because my dad was coming home with over 300 dollars worth of parts that our mechanic told him he needed....what those parts are i have no idea.but lets hope they fix it i guess, ill keep you guys updated...thanks for the help so far

Mechanic had to mark up the costs a little to cover himself since he wasn't making any labor on this one.

Sounds to me like you need find yourself a new mechanic...

Especially if he doesn't think anyone here knows what they're talking about.
