Wow. This is incredibly helpful, thank you so much. A little light reading to do before I go much further in my disassembly.

So it sounds like I don't need to remove the PS pulley, which is very okay with me. I expected that the pulley may hold the aluminum bracket in place if it's not removed. I'll remove all of the nuts/bolts and try it first before assuming to remove that guy. Pulley removal is a brute-force PITA and not something anyone wakes up and looks forward to doing.

How do you use 2 wrenches on the EGR tube? I'll soak mine in penetrating oil and I have a flare nut wrench, but am unsure where the second wrench would go.

Regarding that, I was going by my memory so I could be wrong. I guess the best I can say is be careful.

Thanks for the input. I went lightly on it after using some penetrating oil and it came out easily.

What type of RTV should I have on-hand? I know the gasket kit comes with some, but if that runs out I want to have some extra available. I can get black, high-temp red, grey, etc. Red seems like the right application, but there are too many options.

Which kit did you wind up going with?

Was RTV ever part of the original assembly? I have a hard time visualizing a 1999 assembly line that depended on workers squeezing 3/16" lines of sealant on gaskets.

I went with the Fel Pro MS 98002 T gasket kit. Taking off the intake manifold I can only assume mine is still stock/original, and it had RTV across the zone between the intake gaskets (what was left of it).

You should have been there in the late 70's when GM eliminated a lot of gaskets and went with just orange RTV by itself for oil pan and valve cover gaskets. Bad idea!! It was called G.M.S. (General Motors Sealer). We had a tech we called the GMS kid. He kept a caulking gun with a huge tube of GMS - he would spray leaks down with carb cleaner, smear GMS on the outside, and charge GM for a warranty repair like the part was removed. Same guy knocked over a tray of un-marked rod caps and mixed them up. Spend days switching them around until engine would turn freely again. Didn't last through the test drive.
