Nov 3, 2026, 4:11 AMThe studs in the tractor engine block are absolutely not budging. They’ve been soaked with penetrating oil for almost four days with frequent reapplication. I actually bought one of those inductive bolt heaters off Amazon and got them glowing red hot and doused with more penetrating oil a few times, and finally managed to get ONE out, after about half an hour. Oof.
Nov 3, 2026, 4:14 AMI am long past wanting to save these studs to reuse them, I will bite the bullet and buy more. I just want to get them out D: The problem seems to be that the stud holes go all the way into the water jacket, so they have many years of mineral deposit and rust down at the bottom edge and that is really hard to break.
Nov 3, 2026, 4:16 AMI will just keep heat cycling and spraying them, and I’ll use a stud extractor (more $, waugh!) in my impact driver instead of the “two nuts squeezed together and a wrench” method I’ve been trying to get leverage on them.
@tilton There's a definite art to these things, penetrating oil is one of them, be very careful. Sometimes, tightening them slightly first can work oil in a bit deeper, but don't go far. If you get one moving a bit still tread slowly, applying heat, oil, working it back and forth. Sometimes even imperceptibly back and forth.
As a victim of snapped fasteners, they always happen when I don't got slow.
It's better that it takes a week to get a single stud out than to snap it, put a bolt extractor in there, and snap that and then have hardened steel in the stud :P
