Looking for a couple pointers and maybe some personal experience or other problems anyone has encounter while replacing UIM, LIM, and possiblly head gaskets. car has just under 200k. basicaly im pretty sure these need replaced. car was leaking air and antifreeze out the injector seals. any help would be appriciated. even if its something as small as little tricks to make things easier.
thanks so much.

Head gaskets never ever need replacing unless blown, which ive never heard of happening on 3800s. Make sure you get the aluminum LIM gaskets. Also there is no UIM gaskets on the L67, you have a supercharger instead.

Bag up and mark all your bolts, makes it easier later.

Your UIM is your supercharger, you don't need to replace it. The supercharger gasket is called the plenum gasket at most parts stores, you'll need one.
