I just received a used LS6 intake and when it arrived the piece on the rear that the MAP sensor goes into was loose. I wiggled it around a little and it fell out. One of the tabs that holds it in was broken and it looked like someone had tried to superglue it in and obviously it didn't work. I used liquid ABS plastic weld to repair it but I do not know what GM used to seal it so there is no vacuum leak? I tried to find if there was a part number but had no luck, anyone here ever done this repair?

 

that piece is not available separately .....it is held in by the tangs of the piece

when I got my LS6 mani that piece was damaged....I cut my old LS1 mani apart to get that piece out

it is almost impossible to reach those tangs holding it in to compress them to get it out

 

If you reread my post I need to know what is used to seal it as I repaired the broken tab or tang. I have the manifold clean and ready to put back together now I just need to know how to seal that part when I press it back in?

 

there is a O ring on the piece that seals it

Thanks for the info and pics, now I just have to figure out what size O ring I need.
