Hi, I have got a nasty oil leak, coming from the rocker gasket. About two oil changes ago , I started using "Millers Oils" , 10w - 40 , instead of "Mobil 1" . Could this be the cause of the oil leak ? Should I have stuck to "Mobil 1 " ?
Do I need to torque wrench the rocker cover back on ?
Cheers Terry .

Hi Terry
I doubt that changing the type of oil would cause a leak, I think it would have happened anyway. You don't say what engine you have but taking the rocker cover off shouldn't be to difficult, I don't know if there is a specified torque for the bolts but just tighten them sensibly, the size of the bolts should give you a clue to how tight they should be.

The gasket goes hard after a few years, might be time to buy a new one.

As Xac says, the rubber gaskets do become harder as the years go by.
If your engine has a breather hose coming from the rocker box/cam cover, it could be that it's splitting at the end. I've had this happen on a TD engine, and the split occurred on the underside, where it was difficult to see
