Thanks Wpoll, Jesus, not the value guides again, I had those go on my old Citroen AX GT and, yeah you are right, puff of smoke on start up then it was fine due to oil leaking down them into the cylinder. Mercedes F1 team just got found out for using oil in the cylinder to create extra power so perhaps my French Hot Hatch was ahead of its time. I wish I still had it, they go for £5000 these days and mine was a good one!

Yeap, did the oil separator, as I had the old toilet roll style one, its about 2 years old now so might be worth looking into.

Right, nothing again on the codes, its going in to the shop for them to figure it out.
