Oil leak on my astra g twinport

[mk4vf2011]

Hi i have an 04 astra g 1.6 twinport and has an oil leak thats leaking onto to the metal heat shield above the manifold and the smell of oil is coming into my car through the air vents. I think the oil is coming from a lead that goes into the head and is dripping onto my manifold, what is that lead called?

Hopefully someone can help. Cheers

Some Vauxhalls used to suffer with oil leaking through the oil pressure switches. Does it look like an electrical connector plugged into a switch threaded into the head?
