The Stovebolt Site Forums The Shop Area General Truck Talk Also,what do you use on rusted bolts?

I've had good luck heating the bolt/nut assembly up to a bright cherry red with an O/A torch, waiting for it to cool to a dull red, and then sticking a candle (or just bar wax) onto the area where nut meets thread. The wax melts into the threads and makes it very easy to turn out. I *highly* recommend doing this from the backside as wax will make the bolt head or stud much more slippery, and harder to grasp with a vise-grip or similar tool.

richard2005, do you actually believe the advice you just spouted about used motor oil? I've torn apart engines that have sat for 20+ years and have not EVER seen the internals of a motor eaten away by anything but rust...used oil protects metals, even if used oil has a PH below 7 (naking it slightly acidic) I have a very, very hard time beleiving that it will actually "eat" anything.

If you want something acidic to take rust off of parts, use a product called "naval jelly" and either mist it with water every few hours to keep it from drying out, or place a sheet of seran wrap over it after applying to trap moisture in the work area.
