General Motors has made changes on Chevrolet-built 4.3L engines once again.
The style of rocker arms used on a particular engine depends upon the foundry at which it was assembled. Starting with the 1992 year model, you could end up with non-compatible valve train components.
Engines manufactured at the General Motors Tonawanda, New York facility, use a non-adjustable rocker arm assembly. This engine block is identified by a “T”
stamped on the engine identification pad located on a machined surface in front of the right side cylinder head. The engine components are painted individually,
leaving the intake manifold un- painted.
Engines manufactured at the General Motors Romulus, Michigan facility, use an adjustable rocker arm assembly. This engine block is identified by a “W” stamped on the engine identification pad located on a machined surface in front of the right side cylinder head. At this facility the engine components are
painted black as a completed assembly. This means the intake manifold is also painted black.
Cam bearing caution. 1992 engines manufactured at the Tonawanda facility, use two larger OD cam bearings, one at the front location and one at the rear.
Previously built engines use one larger OD cam bearing at the front location. The installation order of intermediate bearings is also reversed, as the Tonawanda
facility installs cam bearings from the rear of the engine. Installation of the Romulus built engines cam bearings remains the same.
Also new in the 1992 year model on GM 4.3L engines, is the design of the roller camshaft and roller lifters. The new camshaft now incorporates a smaller lobe base circle and the new roller lifter has a longer plunger travel. Both engine plants are using this new design camshaft and lifter. The 1992 GM part numbers are
10144176 for camshafts, and 5234670 for lifters. Engines built for the Oldsmobile Bravada, VIN code W, also utilize a balance shaft,
located in the lifter valley area above the camshaft. This engine design uses the non-adjustable rocker style.
