In this mode damage could occur to the pistons, camshaft, or the lifters themselves. The resulting solution was a package of components that would replace the lifters, lifter guides, camshaft, Valve Lifter Oil Manifold (VLOM) plate. Cylinder heads were required to be removed from the engine in order to replace all the components.
It had the same 0.921 in (23.4 mm)-diameter lifters of the first-generation Oldsmobile engines, rather than the standard 0.842 in (21.4 mm), which let engineers increase the camshaft's ramp speed for more power, 385 hp (287 kW), without sacrificing idle or reliability. Unlike all other 425s, this version was painted slate blue metallic.
The Ford Modular engine is an overhead camshaft (OHC) V8 and V10 gasoline-powered small block engine family introduced by Ford Motor Company in 1990 for the 1991 model year. . The term “modular” applied to the setup of tooling and casting stations in the Windsor and Romeo engine manufacturing plants, not the engine its
The Ford small-block is a series of 90° overhead valve small-block V8 automobile engines manufactured by the Ford Motor Company from July 1961 to December 2000.. Designed as a successor to the Ford Y-block engine, it was first installed in the 1962 model year Ford Fairlane and Mercury Meteor.
The CVH is known for producing excessive sludge if the service schedule is ignored or if poor quality oil is used. The cause is the design of the crankcase ventilation circuit, which Ford revised several times over the engine's lifetime but never completely cured. Due to this, camshaft and tappet wear problems are common.
A camshaft with 301/313 degrees of advertised duration, 0.407-inch (10.3 mm) net valve lift, and 76 degrees of valve overlap was specified for actual production engines in lieu of the significantly more aggressive Ram Air IV-spec camshaft that had originally been planned for the engine (initially rated at 310 hp (231 kW) with that cam), but ...
It used a 0.5 in (12.7 mm) lift solid-lifter camshaft, fabricated-steel-tube exhaust, and a Holley 4-barrel carburetor, producing 275 hp (205 kW) (1 hp/cu in). The car so equipped was called the "D-Dart," a reference to its classification in NHRA D-stock for drag racing, which was the car's only intended purpose.
GM's Active Fuel Management [2] technology used a solenoid to deactivate the lifters on selected cylinders of a pushrod V-layout engine. GM used the Active Fuel Management technology on a range of engines including with the GM Small Block Gen IV engine family, first-generation GM EcoTec3 engine family, second-generation GM High-Feature V6 DOHC ...
