They look like the original type gaskets. Not the way to go if you want a long term solution. Use the aluminum framed gaskets.

where do I find good aluminum framed gaskets, both for the LIM and valve covers. I want this job to be done right! Also, in case I chicken out, I had a local shop quote me 5-600 bucks to do the repairs. Does that sound reasonable?? I know the gaskets cant be more than $100, and I know there is some labor, but is it that intense??

The aluminum framed gaskets are available from the dealer, GM Parts Direct, or one of our recognized vendors - Intense. Felpro is the way to go for the rest. If you're not replacing your UIM, a sleeve to help protect the stovepipe area is available from Bill Buttermore.

The price you were quoted is not out of line. Lots of stuff to remove and get out of the way.

Edit - See Bill Buttermore's post here:

I dont have this stovepipe on the supercharged engine do I? I purchase a subscription to alldatadiy and I did not see any mention of it for my engine. Correct me if I am wrong...

Nope, you're right...my mistake. Please put your vehicle and engine information in your profile so that we don't have to keep referring back to it, and will help people with memory problems - like me. ;)

Ok, can someone give me the part numbers to the aluminum framed gaskets for the LIM. All I can find online are the felpro. When I tackle this job, I need to obviously replace the LIM gasket, I am doing the valve cover gaskets, and the gasket below the supercharger. Should I replace the O rings at the injectors as well? Is there any other gasket/part I need to replace while I am under the hood. I do not want to come back in 6 months because I should have replaced something.

Here's a thread about another member looking for the gasket number.

Yes, plan on replacing the injector O-rings, as well as the coolant elbows in the tensioner. You can get those on the "Help" cards at virtually any auto parts store. You'll need a throttle body gasket also.

interesting info. I may be having this problem as well. coolant is slowly dissapearing, no visible leaks. my car only has 60k miles, though. but i dont know what else it could be. I dont know if its related, but my valvetrain is making ticking noise when i start it, even if its only 1,000 miles into fresh oil. :? i need to read up on this more, obviously. does anybody know of repair/service manuals(where i can get 'em) that cover l67's? my Haynes manual does not.
didnt mean to hijack a thread, kcoop, you just happen to be describing my situation. :)

Look for a factory service manual on ebay or subscribe to http://www.alldatadiy.com/

Thats alright, dont we all hijack a thread?! I just subscribed to alldata, it is less than the factory manual and better than haynes or chiltons. Most shops I talk to use alldata.
