Hehe..hi ole chap, well if you think your not up to doing it then get your mechanic man on to it..although i'm a bit surprised he didn't spot the problem himself! must be a fair bit of oil down the front of the engine if that's the case..
Anyway, just take a look at the cam cover..you'll soon see it's a doddle,
On the left, unclip the cam belt cover and remove or position away from cam cover end.
On the top back of cam cover unbolt the throttle body brackets.
Remove breather pipes off pressure regulator (top left on cam cover) undo the cam cover retaining bolts, on the right hand end two of the bolts incorporate a cabling/pipe retainer bracket..cover should now come off, if it's a bit stuck give it a few taps with a wooden mallet or similar..
Clean the mating surfaces/remove any bits of gasket and have a general wipe around and inside the cam cover.
Refitting = removal procedure in reverse.. just make sure the new gasket stays in place when manouvering cam cover back onto the engine.
Progressively tighten the cover bolts down working in a spiral pattern until all torqued up to 10nm..
It sounds more complicated than it is..if your going to do it though detatch coil lead and battery lead as precautions..
See what you think anyway..
