Have you got a Haynes manual, they tell you in the back......

Just had a look;

Oil Fouling - Wet, oily deposits.

Fault - worn bores/piston rings or valve guides

When i had my Valver i used to have oil on the plugs i found out it was from when i topped it up with oil and missed the hole it seaps down to where the plugs are!

I have had this on my valver too, but only ever ran down onto the leads. Most probable reason though.

Have you had a service/top up recently?

oil on the electrodes of the ceramic sheath of the plug?

if it is covered in oil completly it is proberly that your rocker cover gasket has gone. its a common thing on the clio and mine has gone again for the second time!!

Yeah Rocker Cover gasket happened to me. One of the PLug Wells was completely filled up!

Thanx guys, the electrodes are coated in oil "inside" the engine number 4 cylinder and number2, 1and 3 are okay

check your rocker cover gasket.as part of a service a while ago you had to check the tightness of the rocker cover bolts because they work loose and the gaskets leak.
