Thanks for all the info and concern, I havn't gathered my materials to do this yet, money has gotten real tight until February.

I've got another problem however and I'm debating if I should just have the entire motor rebuilt.

Coolant leaking from the wrong side of the engine!!!
I looked and it's coming from under the MAF? I don't know if it's really the MAF but it looks like a large black bottle cap kinda thing. I couldn't see the exact spot though, I suspect it's where the intake meets the head. So if I'm low on coolant I can hear it hissing air and if I fill it up with coolant I can hear/see it sputter and finally stop hissing as the water fills the gap.

I keep like 3 gallons of water in the car at all times just to make sure it's full and my temp doesn't get high.

Anyone do charity work? :(

There are several coolant line by the throttle body, more then likely one is bad. Not uncommon.

Actually, same thing happened to me. I was new to this car at the time, as well as new to working on cars in general, so I thought it was leaking from where the intake manifold meets the engine block :roll: But, yeah, it was those two little coolant lines going from the water outlet to the throttle body. You might have to get the throttle body hoses from a Buick dealership. Check the big hose that comes off of the same water outlet as well. I will also suggest checking the condition of the hoses that come off the water pump.
