Guys, I desperately need your help.
I did this - all was going well - too good to be true. But when torquing up my valve cover, the bolts suddenly went loose as I was tightening (bolt 1 - and it feels like 2 is the same).

Is this normal or have a stripped the thread? I was using a torque wrench but 6 ft/lb is very low and I'm worried my wrench isn't accurate and has over torqued them.

What are my options?

Thanks.

Edit. And now a bolt has snapped
