Ford Tempo: Engine

Affects Ford Tempo · 1989–1994 — about 243K vehicles.

The hazard

EXTENDED HIGHWAY OPERATION DURING VERY LOW AMBIENT TEMPERATURES (-20 DEGREES CENTIGRADE OR BELOW) MAY RESULT IN ICE FORMING IN THE POSITIVE CRANKCASE VENTILATION (PCV) SYSTEM. IF THIS OCCURS, THE CRANKCASE MAY BECOME PRESSURIZED, WHICH COULD FORCE OIL OUT OF THE ENGINE. IF THE OIL IS FORCED PAST THE ROCKER COVER GASKET, IT COULD CONTACT THE EXHAUST MANIFOLD, WHICH POTENTIALLY COULD RESULT IN A FIRE. CORRECTION: DEALERS WILL INSTALL REVISED, COOLANT HEATED PCV SYSTEMS.
