I removed intake manifold of V8 Porsche Panamera and I checked all intake holes and all valves seem to be closed ?
I was under impression that all valves can't be in closed position ?

Thank's

Hydraulic lifters? I'm not sure how far down they can compress, I'd think they'd still be open a bit even without oil pressure.

I'm pretty sure Porsche's VarioCam allows them all to be closed when engine is off.
