No... It looks like it's a machineing hole, that's been pluged with what looks like a plastic plug!

Do you mean at the back where the rocker cover meets the head? It's part of the rocker cover gasket set! Shouldn't be hard to fix. It may not have been fitted properly or the cover's bolts have been tightened too much (should be 10NM iirc).

Thats the one! Is it part of the gasket set was going to be my next question!!

Thanks for the help

Sounds like the rocker gasket, mine was black. Just follow it around you will soon know

At the back of the rocker theres 2 plug holes inner and outer I bet they put the half moon in the inner slot and not the outer slot.

Take the rocker off and check then move it to the correct position if required.

Nah not if were assuming that the half moon is in the wrong slot. Easy way to tell is the half moon seal should be flush fitted, if theres a small indentation it's in the wrong hole.

Look at this pic you can see what I mean with the right hand side

I havent taken the cam cover off yet but I have had a look and it does look flush and not indented like you said. Maybe the cam cover has been put on to tightly!?
