Is this definitely the correct amount of toque for the valve cover bolts? I would imagine they would be a lot tighter than that!
I'm even wondering if my torque wrench is incorrectly set. I'm sure that's unlikely.
Sounds about right - I've just done some bike clearances and those cam covers were 10Nm, just nipping up against a rubber seal and the covers are quite thin and can crack easily.
That's quite surprising! I would imagine they should be much tighter. To ensure, no air is sucked through the seal. I have tightened mine around double that I imagine
Should I leave it as is? Bearing in mind I have used the car for long journeys etc. Perhaps it would create weak points in the rubber seals if I loosened to correct torque
