oil leak

hello,

have just had a look under my bonnet and found there is what looks like a oil leak on the top right ( if you where standing in front of it ) side of the engine from under the plastic cover ( silver with alfa on it) any ideas i was thinking rocker cover, any idea on cost?

Could be the cam cover gasket.
Easy to get a leak if the gasket is reused.

how much do you rekon that would be?

i am hoping it's to high up on the engine to be the head gasket

Changing the cam cover gasket will be reasonably easy.
The most complex part of it will be that the coil packs will need to come off.
If you are close to replacing the spark plugs you may want to do that at the same time.

The new cover gasket will be about £20 - £25.

what spark plugs do i need, i am hoping to drop the car off at a garage tomorrow and am going to sweden for 3 days and need it when i get back so i am going to try and order the plugs and get them delivered to the garage while i'm away?
