I decided to leave the throttle body on the upper intake plenum and remove as a unit.i just unhooked the two throttle and cruise cables. my car has a bolt instaed of a stud on that pesky bracket that goes to the LIM .....so I didn't have to bend it out of the way. after I removed all the upper plenum bolts it was pretty easy to get it all out from the left side. you will need 10mm and 8mm sockets for this.
The LIM was very easy to remove at this point. I removed all the bolts and put them in my chem clean bucket to soak overnight. 10mm here also. a little antifreeze will puddle under the thermostat. be careful not to spill into the engine when removing....just a tip. now it was getting late so I decided to call it aday. today I will clean up everything for reassembly and post some pics ,

Took 5 cans of brake clean to clean that dirty ol LIM what a project in itself.....dang! but I got her all clean and the heads too and mounted her up. I used the fel pro metal gasket set. I sure hope I made the right choice in that respect
got the throttle body all cleaned up and mated to the brand new upgraded version upper plenum, pretty easy task there, most of my time today was spent cleaning up the cyl head surfaces......that was a lot of time consuming tedious work
. and I also managed to get the front valve cover gasket changed out. sorry no pics.......I ran outta steam
I am an old man after all
still have to change out the rear valve cover gasket and then mount the upper plenum and wire everything back up...ill do that Monday. tom is rest day.
wait till you see the old gaskets and the plenum....pretty bad shape,good thing I tore into this now . it was a disaster just waiting .
I'm gonna pull a spark plug tom and see how it looks I'm not really up to it but if it looks bad now is a good time to swap those too I reakon.
man I am beat. good night!!!

My engine is approaching 80k, and want to do this myself instead of paying 600 bucks again, I also want to do the rear valve cover gasket

the last one is where I'm at now...almost done!! I'm not crazy about how the dorman coolant elbows fit however...they seem kinda loose to me

You were definitely due for a change, how many miles on ya monte? I was gonna get the fel pro aluminum gaskets for the LIM and the Dorman for the upper, that's what I used before

Per the Bonneville guys, I believe ATP is supposed to be the best replacement UIM on the market.
The Fel-Pro metal core LIM gaskets are definitely the way to go. I've used them when I installed my port matched LIM and so far those gaskets are working great.
Replacing the LIM gaskets is a fairly easy task on these cars, but as stated, cleaning the LIM and other parts can be a pain and a project in itself.

I finished it up today
engine fired right up. no leaks! no milkshake!![Smile](https://montecarloforum.com/forum/images/smilies/smile.gif)
kinda of a pain getting the air out of the cooling system tho....made me nervous watching the temp gauge climb
cant help but be a lil paranoid after a job like that. I have a bad back so it was a pretty big project for me. but ita all back together and the engine fires up like a match. ill keep an eye out for leaks tom while I do a cple test drives. thanks to the forum for all tips
car runs smooth as a sewing machine so I decided to do the spark plugs at a later date.
