Welcome to AF.You need a basic shop manual here, it is impractical to walk you thru this step by step, looking at the job, if you are capable of doing this you should be able to see what is required. You may do a search on this site for upper "Plenum" on a 3800,, there may be some procedural info.

What year is this LeSabre? I've got a complete procedure to do the UIM (plenum) and LIM on a Series II 3800 and it covers the EGR stovepipe.

Jackpot! Send me a PM with your regular email address and I will send a procedure with TSBs, pics, part listing and applicable SM repair data as an attachment. On the '97 - '98 you should check for possible EGR stovepipe damage which is covered in the documentation. It will be a large Adobe PDF file.

If anyone else ever needs it you know where to find me.
