Fiat 500 Twinair 2001 85k

I have an oil leak that looks to be coming from the seal between the actuator and the head in the region where a pipe come out of the actuator to the rear or the engine or it could be from around that pipe but don't know? I don't think its the rocker cover.

Does anyone know what is the pipe for? It goes to a sensor to the rear of the actuator but don't know if oil could leak from where the pipe assembley screws into the actuator?

More likely I think is its leaking from the gasket between the head and actuator?

Has anyone removed or changed the actuator and hence replaced that gasket.

I have attached a link to the actuator (shown upside-down) to show the pipe.



The gasket is



Any help along with tips on removing the actuator etc would be much appreciated
as there doesn't seen to be any workshop manual for this engine???

Ok having done some more research on the multiair systems I think the pipe I referred to is the Oil temp sensor for the actuator - can anyone confirm this?



If this is the case it could be this that is leaking?

There seems very little documentation on the twinair engine?
