How to crack/break water bridge bolts

Seems strange to me that some engines apparently have the space and others apparently do not. I wonder if it's a year model thing?

Strange indeed.
Scott, I don't think that's the case.
Mine didn't have the paper gasket when I removed the intake the first time.
There was no way (and still can't with the paper gasket) to put the allen socket strait and well seated in that bolt.
merchauser, maybe it will work with your car.
Just try the socket and see if it's well seated.
If it is, try it.
If not, don't take the chance to strip the bolt head. Remove the intake.
That's what I would do...

I did not think there was room to remove all the bolts either, but lo and behold, Darien did remove the water bridge and the oil filler without removing the intake. Darien had just had it off, and Dwayne's website gave him the thought that the water bridge could be removed without removing the intake again. Had it been my own water bridge, I probably would have removed the intake But it worked out fine for Darien. I'm just not sure there is sufficient room on my cars to get it off without removing the intake.

Consensus among those who should know is that intake removal is often required.
General thought was that there is a lot more tolerance for cast parts than for machined parts (at least on the non-machined areas of the cast parts). When the water bridge and intake are both on the 'small' end of the tolerance, it can be possible to remove the WB without pulling the intake.

I just did this on the 87 S4 and the rear bolt on the driver side of the water bridge was a bear to break free due to the first time ever being removed and having to use an extended Allen wrench. With some choice words and sweat, removed and replaced water bridge and oil filler neck without removing the intake
Thanks for the moral support John!!

I got some great news from the PO, that he removed the water bridge a few years ago to repair a leak; so its
been off, and not that long ago!!
there is no way to squarely get a traditional allen wrench, or long socket allen on that allen head. I made a very
minor attempt with those tools, and stopped as soon as I could "feel" it might round out the head.
so, for those of you that have had success removing this bolt, did you use a ball end style allen?? any other tips or tricks?

I used a long hex bit socket that I cut to the right length with my dremil using a cutting wheel.
and then try to grab with an adjustable or a 1/4" socket?

Darien used a long #6 allen socket like the ones above but with a ball on the end and the hand impact to seat the allen socket, break the corrosion loose, and get it started turning. Then he replaced the hand impact with a ratchet and removed it.

SUCCESS!! that awful bolt is off!
not sure if what I did is the best method, but it worked for me: tried a standard allen key, no luck, and then a std long reach allen,
no luck. bought a good set of ball end long reach sockets, but again, no luck. we all know how it "feels" when something is about
to strip, and, unfortunately, the ball ends gave me no confidence. finally I took a 1/4" impact T40 torx bit with a 6" extension, seated
it firmly with a mallet, and was able to crack it with a 3/8 adapter and ratchet. the torx bit felt much more secure than any other tool.
the allen keys just couldn't seat properly with the strange angle I had to deal with.
didn't muck up the bolt, (well maybe a tad), but still ordered a new one for the reinstall.
not sure I should put it back the same way I took it out?????

Just had this same issue on the “back” closest to the windshield especially the LONG bolt.....soaked them for a day with WD40 and hit them for a few minutes with the heat gun...gave them some good whacks with a hammer square on top with a bronze drift the day after the heat gun...and used a Milwaukee impact gun...hammers it without the chance of the over torque of an air gun. Had to go back a forth a few times, but they came out no problem...order new bolts prior...I’m waiting for the mailman...because I didn’t. Standard hex will work with a 6” extension or buy the longer hex set.
