It's the cam cover usually, you'll need to remove them, and re-seal them.
I removed them on my old car, cleaned them up(is a bit messy as oil sits in the head), and used 3 bond(the best engine sealant!) right round it, especially at the cam seal lobes. Also sealed the spark plug seals and a bit on the bolt seal for good luck! All back together and was perfect.
You'll need to remove a few bits to get access, nothing too difficult.
Failing that, let a garage do it.
