There is an oil leak on my 97 2.0 Widebody somewhere around where the intake manifold attaches to the engine. At first, I thought it was the CAM cover (actually, thought it was the head gasket as it has leaked down). The cover has been resealed but it's still leaking. It only seems to leak when the car is in motion.
Variator solenoid gasket worn.
It is located between cylinder 1 and 2 to the back of the cylinder head with a multiplug connected to it. Held in by 2 torx stud I think. Easy job to do, gasket probably costs a few pence.
Hope this is what it is. See the technical article re changing the cam belt there is a mention of this in there I think.
Jimmy I'm sure the cam cover has to come off to replace the gasket, and if you take the cam cover off be very careful not to overtighten the back right (gearbox end) and front right cover bolts as the cover can break.
