Jeez Thomas... I posted a bunch of stuff over at AZCGP, not knowing you had the BC gearheads on the job!

Any time you need help with this, I'm your man. I have personally installed a stainless sleeve made by Mr. Buttermore in my UIM, and have had my UIM off the car many times. I'll come down there and help if you guys can use me. And yes, I remember Everett.

Make sure you get the GM aluminum frame LIM gaskets for this job. They're indispensable from the standpoint of longevity.

Thomas, as you now probably know already if you read the link Bill Buttermore posted to our TECHINFO article, all the parts and detailed instructions are there, lol. Including torques specs, P/Ns, recommended sources, etc.

Read through that first and then see what questions you have left.

There are at least three very good threads on this and numerous others with bits and pieces. I believe the best of them are linked in that article. Read it all and save Bossty from having to type it all up again. It makes him ornery... :P

.... you guys crack me up, I kinda like having Boosty busy on the job.

Ben, I think that would be awesome if you could come help Everett,

We can do it all in my garage or anywhere else is fine too. The one thing I like about my garage is I know for sure that I have all the tools that I might need.

Anyway... not to hijack myself. I'd love to get Everett fixed up.

I'll try to get him hooked up with the needed parts, get his car in the garage and get it done.
I'll make sure Everett buys pizza and the beverage for Bob & Ben. :P

BTW, I went from work during the last post, to home in this post and still haven't read thru Bill'* post above.
I was just informed that my son has a coupon for pizza hut that will expire Friday and my wife doesn't feel like cooking. Guess what'* gonna happen next? :P

Later,

Either the Dorman intake kit or APN

Last Dorman kit I purchased had injector o rings
PCV
MAP cover
Rear plastic tube for brake booster input
Upper to lower gasket
Tube inside upper for PCV
PCV o rings
TB Gasket
Reduced diameter stovepipes
Name it..

APN is a sleeved upper, no idea what it comes with.

Aluminum frame lower intake gaskets from your local GM contact.

Besides that, some coolant, Permatex Ultra Copper RTV(throw out that black the lowers come with.)
Oh.. and the GM PTFE Pipe thread sealant for the intake manifold bolts.

Oh..and get yourself a right angle die grinder. Then the scotchbrite screw on pads and the holder can be purchased at Napa


Gaskets are a zip.. forget hours.. get it done in minutes.

What the Helsinki are you talking about, Bill? All I've ever used is good ol' red threadlocker, and I've never had a problem.

Yeah, Thomas... when do you need me to come down? Any chance we could kill two birds with one stone and get me tuned while I'm down there? If not, it'* not a big deal... I'll still come help if I have some free time whenever you're planning on doing the work.

If you get the Dorman kit we'll want to install a sleeve. I'm not sure about the latest sleeving procedure in use, so we'll have to review Buttermore'* articles. When I did mine I actually bored out the EGR bore and used epoxy to permanently insert a new sleeve. I don't think that'* the recommended method anymore, but we'll get it figured out.

Blue loctite is the preferred sealant for those bolts. Red doesn't stay pliable under heat conditions. Blue does.

Ben, of course.
Next time we get together, we will get into your PCM.

Thanks, Wren..!! I have the blue stuff, got the GM PTFE, name it... got it.... we used it on Ben'* car,

I'll talk to everett and ask him what he wants to do and when.

Then, I'll keep you posted.. :P

Dorman kits here at O'Reilly'* sell for about $140 tax included but have no heat shield.

Heat shield options for Dorman upper: (PM bill buttermore for parts)

...Bore out to .875+ and JB weld or hi-temp RTV silicone 304 ss sleeve .805" ID / gap = .145" $5

...APN pipe with APN UIM provides shield and .125" gap
...Stock 99+ pipe with APN UIM provides shield and .065" gap

If you get the Dorman kit (or other non-shielded option, or your original UIM is salvageable), I'm here to hype Bill'* pipe

He sold me a shielded one to replace the stovepipe on my Mother-in-Law'* 98 Olds' Delphi UIM. I liked it so much I bought two more for my LeSabres.

I had the exact same occurrence. These engines have such excellent oil pressure, that they force the oil up the bolt threads. I pulled the bolts out that had a puddle of oil around them and coated them with Permatex 2B. Reinstalled them and a year later, still a dry LIM as you can see. The bolt I'm using in the pic is just a common hardware bolt for display purposes.
