1999 Buick Park Avenue Intake Manifold gasket?

8th digit Vin is a number one.

It is the upper intake manifold gasket. Isn't all that aluminum tubing that lays ontop the supercharger the fuel rail? Also we received some O rings that not quite sure where they need to go. The torque is 132 inch pounds. Is that 11 ft pounds and is it ok to use a foot pound torque wrench? Thank you so far for your answers. Not sure if there will be more until after we get into it. If it ok, I will let you know.

Thank you Bluelightnin6, will let you know! Is there a way to view the instructions larger or print them off. The font is quite small?

Bluelightnin6,

Thank you for providing the steps in replacing the upper intake. Apparently, I was mistaken. He is doing BOTH. The upper and lower intake manifold gaskets. Is there anything specific steps to access the lower or rebuilding after done? I really appreciate this site and sure glad you guys are here! Thanks much!

Well all seems to be going well, except for minor things that if they could go wrong, would. Dry, cracked vacuum T's to the MAP and Supercharger. Oh ya, those plastic elbows that go into the water pump ( I THINK, or the bracket near it) cracked also. So, to the dealer tomorrow to get replacements and back to putting her all back together again. There was a 192 thermostat that another mechanic replaced about 2 months ago, not sure why he didn't put in the 195 that's called for? Other than that, so far, it's going well.

LOL. What is left! No, dont answer that! Sounds like almost everything on the motor! I will tell him about the 192/195 thermostats! :) Thanks and will post anything new tomorrow after the trip to the dealer and when he gets back to it. He did change the oil in the supercharger with GM Supercharger oil and thought he'd share with me how AWFUL it smelled! ;) Have a great night, will update tomorrow and thanks again!

Hi Bluelightnin6,

I need the torque sequence for bolting the supercharger back in place. I think the torque is 7 foot lbs, but don't know if it has to be done in a x or z pattern or if it matters at all. Thank you.

OH I want to cry! First thank you Blue for all your help and information, yes, we did find that 17 pounds of torque for the supercharger earlier online. He got everything back together, started it up to add fluids to radiator and now the seal just behind the supercharger pulley is spitting oil all over the place! Called the dealer for a seal kit and of course it is a NS part. So now not sure what to do. Never did one of these and can't figure it is easy. The supercharge was smelling terrible ( didn't know at first that was the source of the smell) and had him drain out old oil as I mentioned, replaced with 2 bottles of fresh and now it's leaking. :( I am trying to find aftermarket parts but not sure which are correct and who to trust. If you have any information or suggestions I sure would appreciate anything you could offer. Just looking confused the heck outta me.M62, M90, viton, nitrile seals, couplings, bearings. All or just the seal? It was replaced about 90,000 miles ago while still under warranty and I do not hear the same gravely sound I heard coming from it then. Thanks Blue for all your help and anything you can offer. Not even sure who is going to attempt this repair. Donna

Does anyone know if I can take the belt off the supercharger and drive it without harming the engine? I am having trouble finding a replacement that is reasonable.

Hi,

We did not take the supercharger off- I wasn't sure how much air the engine would get with it off, so after calling many places, we found a used one at a salvage yard that gave us a 4 month warranty for 250.00. Decided to go that route instead of rebuilding the nose blower. My brother( mechanic) wanted to bypass it, said that the belt didn't operate anything else but wasn't sure how it would effect the MAP and all the other things that sinc together on this electrical beast! We took it on a short trip this past weekend and I did notice a "slight" difference in the wy the tranny shifted. It seemed to shift normal at about 20-30 mph and then at the 40-50, while under acceleration, it seemed delayed more than usual. Don't know if this is because there is more power to it now with the SC working well or if there was a hose or anything left off while replacing all the lines, etc. No slipping, just a few second delay-hanging there longer than before.
