Tips and Tricks on getting manifold bolts off of Y-Pipe

[m1dn]

Hey folks, looking for any tips, tricks and suggestions on getting Manifold Bolts off of Y-Pipe
Bolts on mine decided to become one with nuts

I tried a little penetrating oil and only have medium impact ( ~500lb breakaway torq ), no luck, doesn't budge.

Right now looking around to see if any specialized shops have a rental high-torque impacts and see if i can break this ***** loose.
Was also going to try longer wrench, hammer and doing it by hand, but i'm worried about making the nut round.
The space is so tight i'm not sure i could get an angle cutter there to get it out as well.

Might see if you can get some heat on it.

Also, I’ve had some luck with rusted bolts alternating between trying to loosen it and trying to tighten it in short bursts while putting some penetrating oil on it in between. My preference is aero Kroil.

If you put a nut busting high torque impact on it and just go to town, you’ll likely end up with a rounded nut, not desirable, or a broken bolt.

Thanks, will try to play around with propane torch and see if i can fit in there without melting o2 sensor wires ( and if do, i'll just replace it )

My suggestion is to use an oxy-acetylene torch to heat the nut. If you can clean the threads of the stud first it will help. Be careful! You might snap that stud with too much torque.

Cut off wheel and buy new ones careful not to cut the pipe

That's my plan B :joy:, get a tiny one to get in there and cut the nut off

Harbor freight die grinder or dremel with a cut off wheel works good for right spots

I live in Canada and visit HF probably once a week, still not sure why everyone hates it, I absolutely love their tools for small use cases like these
Prices are also Times cheaper than Canada

MAPP gas will give more heat than propane. You can use your propane torch head.
