I just bought a 2002 Bonneville SE with 73K. After about a day of driving it noticed the LIM leaking on the passenger side. After reading the forum, I know it has to be replaced ASAP.

My question is:

-What is the GM part number for the aluminum LIM gasket?

-What other part numbers do I need? Upper intake, Throttle Body, 2 coolant elbows, what else? Can anyone give me the correct part numbers?

-What else should be replaced while apart? Injector o-rings? Anything else?

Thanks for any and all help.

Everything you need is here. Go under Grand Prix, then under gaskets and adhesives. You'll need - an L36 Upper Intake Gasket, Lower Intake O-rings, Lower Intake Manifold Gaskets and a Throttle Body Gasket. The coolant elbows and a tube of RTV Ultra Copper you can get either through ZZP or from you local part store for a little cheaper

It says the lower o-rings are for supercharged, mine is NA. Do I still need them?

Also, are all injector o-rings the same?

You will want
Lower intake gaskets (I'd suggest dealer/Intense Racing for better fitment)
Coolant elbows Dorman #47065
Upper intake (Rockauto Dorman kit as it comes with almost anything you need for the job)
Can of brake cleaner
Can of throttle body cleaner
One tube of Permatex ultra copper RTV
Gasket scraper

That should do it for a UIM/LIM gasket replacement. The Dorman kit has fuel injector o-rings and all the goodies that you'll need to do the upper. It'* a good setup and at Rockauto prices plus the discount code for the forum,it'* about $85 shipped.

Thanks for the help guys. It looks like I will tackle this later in the week!
