Broken upper bypass fitting
Hi Everone,
1994 Bonneville SE N/A. I have found a tremendous amount of usefull information in this forum that has been of great help to me in maintaining my own pontiac so I wanted to pass on a little bit of my experienceI so that mabey it might save a little bit of headach time for someone else. I have had the plastic fitting for the upper bypass hose also break flush at the manifold this weekend. After removing the Altenator out of the way, I first drove a 5/8 inch wood boring bit,( the kind that is flat at the buisness end with a short starting tip in the center of the blade and the shank is a hex(six sided) end that goes into the chuck of a drill), I drove it as much into dead center as i could which did take some amount of paitience as there isn't much room to swing a small tapping hammer(ballpeen) and with nothing solid in the center for the tip of the blade to grab into i did have a few false starts as the blade would drift off center easlily. When i was satisfied it was driven in about an inch or so and centered, i used some vice grips on the shaft and a hammer to tap the bit back out. I then used a 3/4 inch wood bit and drove it in the path that the 5/8 blade had made for me in the center of the fitting. This took a little more effort and time but once it was in place I was able to put an 8mm? six point socket, 1/4 inch drive, and a 1/4 drive breaker bar on the hex end of the shank and reversed(unscrewed) the plastic piece out of the manifold. It did protest and I didn't rush it but it did come out in one piece with just a couple of small palstic pieces inside back behind the manifold threads that did come out when I put my three horse shop vac hose up to the opening and made as tight as seal as iI could. I am hoping this may help some one else. II did replace the fitting with a metal one from Autozone.
Thaks again for a great forum.
Yours in Christ,
Aubie

Wow! I wish you worked at the shop that did my LeSabre when mine broke. Took them 2 days and about 400 bucks for the same procedure.... (And I have all those tools in my garage)
Good thinking!!
