im sure,,the cover isnt like a head gasket,it only has the crush the rubber gasket down.
Ok so just a little snug tighten then
I do typically prefer to use a torque wrench though. I sort of have monkey grip and always over tighten stuff
Some of us have tightened enough screws to have the feel. According to this chart, 6mm pans are 5 to 8 ft lbs. So with your torques wrench just go to 6ft lbs (72 inch lbs). Maybe tighten one with the "choke up on the wrench" method, then check it with your torque wrench to get the feel for 6 ft lbs.
Also, there is some value to having them all equal, which you may do better with a torque wrench.
Then if there is a leak, you can cinch them up a tad more.
But in the end, you can do them with a regular wrench, choked up on the handle. Once you get the feel. AND, no sense in making them tighter than they need to be to seal the gasket.
