Thank John, just the reply I needed
It's an 8valve so no just running Stock size cam breather with correct sized piping
I've not done a leakage test... iwill get on it, the oil I'm running was just temp for a few hundred miles so I could flush the system and put a new filter on, before putting some decent oil in
It's not forged, currently double h/g.. The oil seems pretty thin and the whole car stinks of fuel
I did have wide band but I decided I was selling up not long ago and it was one of the first things that went, not yet replaced it.. But I will be looking at an aem w/b kit ASAP
So I think my next plan is to get it booked in for a map ASAP and flush the oil and filters and bang some fresh plugs in
