Ford Essex V6 engine CanadianSee also Ford Essex V6 engine UKThe Ford Essex V6 engine was a 9. V6 engine family built by Ford Motor Company at the Essex Engine Plant in Windsor, Ontario, Canada. Unlike the British. Essex V6, the Canadian Essex used a 9. V configuration, in addition to having different displacements and valvetrains. With Fords Essex Engine Plant idled as of November 2. Ford Duratec 3. 5, and last ones were found in 2. F 1. 50 regular cab only. The Canadian Essex is an overhead valve OHV, or pushrod design featuring aluminum heads, which reduced its weight considerably and made it a very powerful engine for its size. The engine was initially offered in only a 3. A 4. 2 liter version was introduced in the mid 1. F 1. 50 and Ford E Series, later, the Freestar and Monterey. The 3. 8 L V6 was replaced by a 3. L version in 2. 00. The Essex and the smaller Vulcan V6 were the last traditional overhead valve engines built by Ford. The Canadian Essexs origins are somewhat controversial. A common, but erroneous, belief is that the Essex was based on the 5. L Windsor V8 engine with 2 cylinders missing, because they both have a 9. OHV, and that a 5. L V8 less two cylinders would make a V6 displacing around 3. Though the practice of deriving a V6 from a V8 was not unheard of, several important differences between the Windsors design and the Essexs, such as their considerably different bore and stroke, made a common design lineage implausible. One source states that the Essex is instead a reverse engineered. Buick V6 engine. 2 Toward the end of the 1. Ford needed a new six cylinder engine that was powerful and compact enough to be used in a mid size car while meeting increasingly stricter emissions and fuel efficiency standards. Since Ford did not have an engine available that could be readily made to meet these requirements, one needed to be developed. The quickest and least expensive approach in accomplishing this was to copy an existing engine from a competitor, which ended up being the Buick V6 from General Motors. Fords resulting V6 was very similar to that of the original Buick engine down to an unusual external oil pump design that was common in Buick engines and without precedent in modern Fords and had a nearly identical displacement. FRAME AND ENGINE SERIAL NUMBERS. There is usually no engine number stamped in the block, but the transmission bell housing was factory stamped with a number which. Had a few emails over the last month or 2 from folks that have googled upon us with a similar Ford lehman engine to ours, ours is the Lehman 2715e. In fact, one of the only major differences between the two engines early on was Fords use of aluminum heads as opposed to the cast iron ones used in the original Buick design. However, in the years since the Essex V6s debut, design revisions from both Ford and GM to their respective V6 designs have differentiated their engines from each other to a point that any relationship between the two designs is not as obvious as it once was.
