Modern cars seem to go from crazy tight, typically for single use stretch bolts, to crazy loose. Working on my son's diesel Citroen a while ago the torque figure for the injector bolts was I think just 4 Newton metres. Needless to say they were done up with as much gentle feel as I could muster with a 1/4" drive socket. How many there are out there with stripped threads in the aluminium head that are just gummed up with thread lock is anyone's guess. Cheaper for the manufacturer to stick a bolt in than specify a stud with a nut of course.
Good tip above from AG Wood about giving a rarely used wrench a couple of dry runs in the vice before using it. Makes a lot of sense and hadn't occurred to this amateur fettler. Thanks!
