Engine Lubrication - Description
DESCRIPTION
The lubrication system is a full-flow filtration, pressure feed type. The balance shaft module (BSM) is mounted below the ladder frame and chain driven by the crankshaft. The BSM consists of a non-serviceable pump, oil pressure relief valve, and a non-serviceable balance assembly.
NOTE: Not all blocks have the bolt on timing chain oil squirted. Engine blocks either have a bolt-on oil squirted or a 1.0 mm hole (1) drilled into the oil gallery passage. Engine blocks with the 1.0 mm hole no longer use an oil squirted even though the threaded mounting hole may still be present.
