As wampuskat stated check or have your wrench checked.
I rebuilt my 22r using a craftsman 3/8 digitorque and had a leaking head gasket 5-6 months later. Blamed it on the aftermarket gasket but when tearing it down all the head bolts are not tight enough. So now I am blaming it on stretched head bolts, got new toy head bolts and I am putting it back together but I am bothered by the fact these are heavy bolts to be stretching. Had an electronic torque wrench setting under the x-mas tree for my son so I unwrapped his wrench to see what it said compared to my old craftsman. Had the head bolts torqued to 56 ftp(if I remember correctly) and the electronic wrench needed 50.5 ftp to tighten them more. To find which wrench was correct I put the wrenchs in my press and hung different weights on them. The electronic one was always correct and the craftsman was progressively off - the higher the torque value the more it was off. Pulled the pan and all the mains were just below the min torque but the lowers were fine.
We had a big laugh that my sons new torque smelled of oil.
