FORD 4.0 OHV COLOGNE

The 4.0 L pushrod (242/245 CID; 3958/4009 cc, with a 100.0 mm (3.94 in) bore and a 84 mm (3.3 in) stroke.) version, although produced in Cologne, Germany, was only fitted to American vehicles.[3] The OHV engine was produced until 2000 and was used in the Ford Explorer, Ford Aerostar, Mazda B4000 and Ford Ranger. Output was 160 hp (119 kW) and 225 lb·ft (305 N·m). Though there is some variation, typically 155 hp (116 kW) is quoted as horsepower for 1990-92 applications.[citation needed] This evolutionary redesign of the American 2.9 solved many of the reliability issues that plagued its predecessor. A stronger cylinder head design eliminated the 2.9's common failure of cracked heads. Hydraulic roller lifters replaced the simple hydraulic lifters used in the 2.9, which were sometimes overly sensitive to oil contamination, often requiring the lifters to be replaced prematurely. However, one major design fault was not completely eliminated: Valve rockers and upper pushrod tips still received poor oil supply, resulting in eventual wear to these areas, and consequential valvetrain noise as a result of the increased clearance. Required replacement of these parts is common in older engines.[WIKI]
