Thanks guys

I have taken the top cambelt cover off and run the engine.....I cant see any oil coming from anywhere in there but I can see the top part of the rocker cover gasket looking rather sorry for itself. This was replaced because the old one was leaking.....I didn't use any gasket sealant on the new one and I dont know if I should have tightened the rocker cover bolts in a certain order and to a certain torque? I just did the up tightly and that was it......Wonder if it could be the rocker cover gasket now?
