SteveB Posted November 16, 2010 Share Posted November 16, 2010 psv? pcv - positive crankcase ventilation. The little valve in the side of the block that vents the crankcase fumes back to the inlet manifold when conditions are right. Link to comment Share on other sites More sharing options...

Follow the pipe that comes from the intake manifold round to the front of the engine. The valve is on the end pushed into the block. It is either on the gearbox end of the block near to where the thermostat housing is, or it's on the oil separator behind the exhaust manifold.
