Default Replacing LIM Gasket

I have a 02 SE Bonny and I am replacing the LIM gasket. I have all the bolts out but cant seem to break it loose. Any ideas?

There are some bolts that are way down on the corners. they get covered with grim. Look there and you will find them.

You have probably forgotten the long stud style bolt on the drivers side.

Orielly auto or Auto zone have Felpros for the LIM for $39.00 included in the kit is the Black RTV
UIM is $9 and includes the orings.
I would buy an elbow just to have it.
I have changed the gasket on 3 motors so far and don't remove the TB.

I also recommend leaving the oil in it (drain the coolent) unless it is truly comtiminated......this way once you have the motor back together and running.......let it come to temp....burb out the air bubble THEN change your oil.

I am new to this forum, so forgive me if these questions have already been answered. I am planning on doing the same repair soon on my 02 SSEi. I believe that this is the required repair. I am losing coolant with no visible leaks (that I can see), smoke or smells. Is this all the parts to do the job? Is there a tech note on doing this with the supercharger?

lol, you guys just helped me do mine, and even though I'm confident with a wrench and do a fair amount of stuff to the car, the whole job took me about 10 hours total. That includes a fair amount of cleaning things, like the LIM and various bolts. I'll bet I could cut that in half if I had to do it again now that I know my way around the job.

Advice to the posters getting ready to tackle this, since I am fresh off doing this job for the first time... take your time, take pics of things along the way if you have a camera for reference, and enjoy the process. Messing with the car is zen-like for me.

A tip... I took the LIM to the local car wash, set it on the floor of the bay and hit it with the degreaser, then power rinsed it with the wand. Worked great. Just make sure it'* 100% dry before putting it back in place. I let mine sit overnight inside where it'* warm.

My thread about this job is still on the first page of this forum, use it, and Danthurs' write-up is very good, too. Between Dan and Bill, y'all will be fine.

On the oil change, I have a alternate approach. While the intake manifold is off and just before putting it back on, pour two quarts of cheap oil to flush out any crap the came lose from the manifold removal and cleaning. Before starting, drain oil and refill. Run for a few minutes than change oil and filter. This MAY prevent foreign crap from being cycled through the engine and possibly scaring cylinder walls, etc.
