oil shown by the first ignition coil

Hi all, my car has only 50.000km, and i see some patches of oil by the first ignition coil entering the engine.
Is it common to have it?
What could be the reason?
 
Its either oil spilt from a top up or the rocket gasket may be leaking.

Some people report slight leeks around the bolts, this can be rectified by a bit of sealant round the bolt. I had to have the rocker sealant replaced under warranty as I had oil leaking into one of the cylinders.

Thanks, i just saw other guys posts. i guess the oil leak looks the same as the other guys leaks. It must be from screws. I will use some engine sealant to fix the problem, as my car isnt in guarantee.
