Head Nut Torque

[DHDamo]

Could be just radiator gunk. I just took the cap off and it's got some crud under there but not oily at all.

Back in the olden days, when we still made things in Australia, i worked for a fastener company that used to check its fasteners with calibrated torque wrenches, took all my torque wrenches to work to check them and they were miles out, up to 15% if i remember rightly.
The torsion bar wrenches are accurate, the ratchet spring style less so.
And with the ratchet spring style, when you are finished using them, unwind them to zero, as the spring can sag and loose its accuracy, Colin.

I doubt that's an issue, my fiat 124 has that gunk all the time. however someone else may know more about this common "gunk"

thanks Colin, you answered my question before I asked. Torsion bar type seem to be the go.

Yes, gr I'm hoping it's just gunk. My understanding is that it's less than ideal but harmless compared to a blown head gasket.
