Ford Essex V6 Engine (Canadian) - 4.2

4.2

A 4.2 L (256 cu in/4195 cc) version of the Essex V6 appeared in the 1997 model year as a replacement for the durable, but aging, Ford 300 straight six in the F-150. Like the 3.8 it had 12 valves and pushrods, but the 4.2 featured a longer, 3.74 in (95.0 mm) stroke. Bore diameter was the same at 3.81 in (96.8 mm). Initial output of the 4.2 L V6 in the F-150 was 202 horsepower (151 kW) at 4800 rpm and torque of 252 lb·ft (342 N·m) at 3400 rpm. Ford Power Products sells this engine as the ESG-642.

Ford experienced problems with this engine in the 1997 and 1998 model years. These included issuing all 1997 engines made at the Essex plant with a bad front cover gasket. The lower intake manifold has a bad reputation for cracking at relatively low mileage. Ford ended production of the 4.2 L V6 after the 2008 model year, marking the end of the Essex V6. The engine's final recipient, the F-150, was only available with V8 engines starting with the 2009 model year until the 2011 model year, when the 3.7L Duratec was made standard.
