ZT190+ smell of oil through heater

[Geoff130]

As the title says my ZT smells of oil fumes unless the AC is on recirculate. I've checked the breather pipes and the T piece, they are fine, any other places to check?

Have you had a recent oil and filter change? If so it might be spills that are burning off. If not, possibly a check over all the engine block you can see to check for wet patches of oil. See if there is oil on the underside of the engine. On a Volvo I had the PCV got blocked and caused me all kinds of problems - if this one has a PCV, it is worth checking it too.
Hope that might help? oswestryalex

It is loosing a bit of oil somewhere, about a litre per 1000 miles, it doesn't noticeably smoke and there aren't any drips when it's parked. There is a bit in the throttle body and VIS manifold that I noticed when I replaced that recently.
