The air stream was from the end of the PCV hose (off timing chain
case)
Air from oil filler cap was very very slight, if at all. Streatched
some freezer film over it to see if it was sucking or blowing -
remained flat!
Filler cap is a black plastic thing, appears sealed, but may have an
internal vent hole of some sort. No other breather pipe to valve
cover.
