Mark Shaw Posted October 24, 2016 Share Posted October 24, 2016 Just a rule of thumb: Start in the center and work your way out in a circular pattern. 1 Link to comment Share on other sites More sharing options...

NTX5467 Posted October 26, 2016 Share Posted October 26, 2016 What Mark said, plus do the torque in sequence such that you start low and end up "at spec" in about three passes around the circular pattern. For example, if the final torque is 60, start at 30, then 45, then 60. This gets things pulled down evenly and compresses the head gasket evenly.

seando Posted February 19, 2018 Share Posted February 19, 2018 These torque settings are just what I was looking for. Before I start, any tips and tricks for loosening the rusted nuts? I am going to soak in Mystery Oil and apply heat if necessary but man, if I break one of the stems... Link to comment Share on other sites More sharing options...
Mark Shaw Posted February 19, 2018 Share Posted February 19, 2018 Penetrating Oils Machinist's Workshop Magazine (March/April or May/June, 2007) actually tested penetrants for break out torque on rusted nuts. They arranged a subjective test of all the popular penetrants with the control being the torque required to remove the nut from a "scientifically rusted" environment. *Penetrating oil ..... Average load* None ..................... 516 pounds WD-40 .................. 238 pounds PB Blaster ............. 214 pounds Liquid Wrench ..... 127 pounds Kano Kroil ............ 106 pounds ATF-Acetone mix....53 pounds The ATF-Acetone mix was a "home brew" mix of 50 - 50 automatic transmission fluid and acetone. Note the "home brew" was better than any commercial product in this one particular test. Our local machinist group mixed up a batch, and we all now use it with equally good results. Note also that "Liquid Wrench" is about as good as "Kroil" for about 20% of the price. 1 Link to comment Share on other sites More sharing options...
