Where's it leaking from, the front near the half moons?
Did you use any sealant when you put the cam cover on near the half moons, you need to do this, and don't be shy with it either if you want to guarantee it not to leak.
I used sealant on both sides of the gasket and on the half moon seals where it meets the gasket.
I am pretty sure it is leaking from there as it cant be anywhere else? And also you can see it dripping down the head around the front.
I actually am guessing it is coming from the half moon seals as i cant see it from anywhere else
