I'm attempting my first valve adjustment on my '74 2.0 ... and after thinking I finally got an idea as what to do, I was going to loosen the jam nut to move the adjuster screw, and my 13mm wrench does not fit.

A 14mm will fit, but it has a little slack.

I didn't want to go any further without a little input. The motor was rebuilt just before I purchased the car several years ago, but I have zero paperwork on the rebuild.

Any ideas? Suggestions? Or, are these just worn/rounded 13mm nuts?

Thanks

Worn and rounded some people seem to overtighten them to crazy torque which isn't needed...
