Winter prep project

Getting my 560 ready for winter and saw the exhaust manifold is done for. I already have new intake and exhaust parts ready to go. What's the best way to take the old one off without snapping the studs?

Soak everything with a good penetrating oil for a couple days before you touch a wrench. A little heat on the nuts (not the studs) helps too. Work them back and forth slowly instead of forcing it all at once. If any look really bad, double nut the stud and back it out rather than risk snapping it

This tip is super helpful but I just would like to ask, when you say "a little heat," are we talking propane torch level or something gentler? And for double-nutting the stud, is there a trick to keeping the nuts from slipping while backing it out?

The propane torch heat is usually enough for this job since you are just trying to expand the nut slightly and break the rust bond. Do not dwell on it in one spot but keep the flame on the nut and flange area and move it around evenly.

For double-nutting, just thread two nuts onto the stud and tighten them against each other firmly so they lock together. You need to make sure that the nuts are jammed tightly enough that they act as one piece. This will keep them from slipping while you back the stud out.

hi @field2feed, just wanna say that if you do have to resort to the double nut trick, make sure you use a proper, high quality six point socket, not a twelve point, to back those studs out.
You need maximum grip to avoid stripping the threads before they even move
