rusty bolt remover

[QuickMick]

Im fixing my exhaust system to address a leak. im just gonna yank the whole thing out so i can check it all while im fiddling with it.

the problem is that the bolts that attach to the engine have rusted... im concerned about using too much torque and snapping them. any suggestions on some to squirt/spray/rub on them to help loosen them up a bit? i was thinking liquid wrench...

thanks

Would this be the three studs that hold the manifold to the block ?

yeah, and if i pop one im gonna have to tear a lot apart to get to em

PB Blaster or Kroil. WD40 will work about as well as cake frosting..

Well

It should be three NUTS on studs ? PB and time with small movement to allow it in

The studs go into a dry area of the block VS the ones on the head which are in the water jacket and can really get stuck

In addition to the PB Blaster, I recommend using an Impact Driver to loosen the nut (if you can get a shot at it).
No, not the pnumatic or electric tool, one of these;

... Also if you take my suggestion above, be sure to use a 6 point socket.

haha Maine Sail has done this before. I second the above.
Other option was to break off the stud, drill and tap new threads in. But that's a real workout on your flexability, and tools.

PB-blaster is good stuff.

A propane torch and wax works well too - heat the nut for 5 minutes with the flame, then melt wax into it.

Obviously SAFETY FIRST... don't do this near gasoline or anything else remotely flammable. Harbor Freight sells nice welding blankets that will shield surrounding areas.
