Broken egr stud

[ndamico]

Yes I got over zealous... Snapped it off. Have been soaking with pb blaster. Just wonder about making the right move next. I can weld a bolt to it, drill it out, what's best?

If it's a threaded in stud, I've had good luck with welding a nut on it and removing it. Plus the heat from welding will loosen it as well. But some studs are cast into the part and are basically non removable. Good luck.

Heat and some PB Blaster. Also there are some products out there that cold shock it.

Definitely weld a nut and pull.
Should pull right out that way.

I believe that’s a threaded stud. Heat, cold, pb, weld, vice grips whatever it takes to get the job done.

Had several like that in other vehicles. Heat alone (getting it red with an oxy torch) and it was easy to get out as it cooled. The nut is definitely an option but I would think unnecessary

If you have a welder readily available it's more than worth the nut.
As said before, it will put some heat into it and then you can use a socket and driver.
Much easier than an extractor, which I always find to be a big PITA, especially on the vehicle!

Do the nut welding since it is easier to get a wrench to grab. Careful of the fumes burning off the coating on the nut - they can be pretty toxic. If it breaks off flush - tig welding does the trick for me. You can raise and lower the heat for as long as you want on only the focused a
Part and when ready start to add filler metal to grab with a vice grip. I haven't found one I can't get out doing that including break bleaders unless on a stainless bolt since I don't have the knowledge or material for that. I have ruined a few holes with drilling and easy outs though.

I had a egr stud break once. The issue is those studs are a good bit longer than needed. Even with the stud broken I could fit the flange on there and a nut. So before you do to much work check that.

Take a pipe tap(3/8" IIRC) and run it down the hole being careful not to drop shavings into the turbo. Then you can use a standard pipe plug and plug the EGR opening off.



Of course your EGR port is no longer usable after that.
