Question
Where is the Crank Case Ventilation Valve Located

Answer
Hi Mick,

here's the text from the workshop manual:

Crankcase Ventilation
The crankcase ventilation system is pressure regulated by a valve mounted at the rear of the inlet manifold. Vacuum supply ports are incorporated on the valve for the power brake booster and the fuel pressure regulator. The pressure regulating vent valve varies the vacuum applied to the crankcase depending on engine load. The valve is balanced between spring pressure and the amount of manifold vacuum. At idle when the vacuum is high, the valve closes down and only allows a small amount of blow-by vapours to pass into the manifold. At part to full load
conditions, the spring opens the valve and additional blow-by gasses flow into the manifold.
An additional tube leads the blow-by gasses through the manifold and up to the mixing plate.
The crankcase ventilation system is completely sealed. Hose clamps are used at all connections
to ensure that the system does not contain any leaks.

The crankcase ventilation system uses a cyclone seperator to purge the blow-by gasses of any oil
vapours. The oil vapours condense in the seperator and drain back into the sump.
A water drain plug is located at the lower LH rear corner to drain coolant from the crankcase.
