96 ultra, Have an intake manifold leak possibly?
So the other day i noticed my temp gauge going up. I went to go add some water to see what was going on and it took a whole gallon. I then looked under the veichle to see if I could see any leaks. Which I could not see anythig dripping or when I looked under the hood i did not either. Then I thought crap I hope it is not my intake manifold agian because my previous 96 lesabre did that and its the same engine. I checked my dip stick and everything looked normal that I could tell. So I ran it for another day and noticed a noise coming from the enige so I opened up the hood and seen that there was a right hard plastic i think angle coming out of the intake maniflold and leading throw the belt tensioner and looked like it went to my heater core. It was leaking fluid out of the angle where it connected to the intake manifold. It was bubbling out. I think that is what the noise was? Someone was telling me that I could try running stop leak through my radiator to stop the leak. Not sure if I should try or not in fear of what if there is and intake manifold leak would that make it even worse? Does anyone know what the name of the part is or how hard it is to remove? Please help have to drive to work!

It is a plastic elbow that is known for failing on the Series 2 supercharged engine, which is what you have in the '96 Ultra. Those items can be found in the HELP! section of most auto parts stores. I am unsure of the complete replacement process, but I believe it is somewhat involved, especially if you have not done it before. Using stop leak is one of the worst things you can do, as it gums up everything, and this leak will only get worse. Also, being a supercharged engine, and not the NA Series 2, it does not suffer from the UIM failures that you would have had to deal with in the LeSabre.
Suggestion: Feed it coolant/water until you can fix it, or it completely breaks. It must be repaired quickly (days, not weeks) before you run it out of coolant, and overheat the engine.

You may wish to look in to this thread for reference:

If you have any questions, please post them in the thread you started (this one), and do not dig up the old one that I just referenced. The gearheads should be along shortly to help with any clarifications necessary.

Thank you for the help. I will be stoping at the parts store on the way home. I will also post my findings and what happens when I change it. One more question though. As long as I keep the coolent/ water at a high level everytime I drive and the car doesnt over heat. It should be okay to drive corect?

You could probably get away with it, but if it runs out of coolant, you are out of luck, whether stranded where you are, or overheating. The primary concern I would worry about at this time would be if that elbow catastrophically fails, and dumps coolant. Also the coolant boiling point will be affected as well, as the system is not maintaining proper pressure, so don't go pulling any massive mountain passes or anything either.
