Do I need to use a torque wrench for the nuts when changing the valve cover gasket or can I just do it by 'feel' ? :confused:
 
Use of a torque wrench is highly recommended, because it is important that the pressure is applied to the seal equally. If the torque setting are not the same this will cause oil leaks.

Also, not sure about your engine, but typically the torque setting for the cam cover are quite low (8-10NM) and it is therefore very easy to over-tighten, again causing oil leaks.

An experienced mechanic should be able to do this by 'feel', but as said a torque wrench is highly recommended.
 
Thanks!
The seal is the reason for the smell of hot oil every now and again (I think ) because there's evidence of oil at the front and back and the side above the manifold of the cam cover.
