Yes, it does have a vented oil cap with what looks like steel wool in it. Where should I check for that PCV valve? Have not seen one in the hoses.
Another thing I found... the rubber line coming from the road draft tube goes over to the intake manifold a usual. Then the lines go into a junction, one line goes to I think the hydrovac brake unit under the driver running board. Under the passenger side there is a large tank which may be for vacuum also, I have not traced the lines out yet.
They have also added a vacuum gauge under the dash, it works and reads about 15 in of vacuum at idle. For some reason they wanted to track the vacuum pressure on this truck.
