i just finished doing it while changing a lower intake gasket. its not hard to change on a 3.1...a little harder on a 3100.

 

you can JB weld it, or silicone around it if you want. replacing it with the newer brown gasket is best. i have pictures of all the junk if you want me to post them.

 

just let me know!

Did mine couple years ago, got a new gasket, 1/8 bead of red RTV (+5 horsepower) and it never leaked again.

Weld it in!!! :twisted: :lol: j/k Sorry, I have no advice for that. I tried replacing mine once and that o-ring was rock solid, so I could get that darn thing out. Guess I'll have to try again later...

with the TB out of the way it's really easy to get to. i had to grab mine with a channel locks and wiggle it out.

yeah that o-ring needs to be replaced. when i replaced mine i had to cut it off with a razor. it was like hard brittle plastic! i never used any sealant or RTV. i just replaced the o-ring and stuck it back in. no leaks here.

Use the GM )-rings .. they seem to last longer GM # 10477565 They come from GM Parts Direct 5 to a box

Dave, I've got a few pics as well. It's very easy, I just used the new o-rind. It lasted me 13 years, and 150K miles, so I figure I'll be dead by the time it needs done again. Plus, it's only $.98 (Canadian could be like $439 so watch out.) :lol:

It's a piece of cake on a 3.1! I wrote my own tutorial on it on here. DO get a GM ring. It's like $3 from the dealer, and it'll last longer than the one you buy at an auto parts store.
