A gear-type oil pump is directly driven by the crankshaft and 
draws oil from the oil pan, via the suction pipe. If then passes 
the pressured oil through a full-flow disposable oil filter, to the 
main oil gallery in the cylinder Block. An oil pump pressure 
relief valve and oil filter bypass valve are incorporated in the 
system. 
From the main oil gallery in the cylinder block, the cylinder 
head and crankshaft main bearings are supplied with oil. 
The camshaft bearings and hydraulic tappets are supplied 
through the main feed galleries in the cylinder head. Vent 
valves allow air to be expelled from the oil galleries in the 
cylinder head. The balance shaft journals are directly fed from 
the crankshaft main bearings. The connecting rod bearings are 
fed via passages in the crankshaft. The oil returns to the oil 
pan via passages in the cylinder block.

Service Precaution 

CAUTION:  
Always use the correct fastener in the proper location. 
When you replace a fastener, use ONLY the exact part 
number for that application. ISUZU will call out those 
fasteners that require a replacement after removal. ISUZU 
will also call out the fasteners that require thread lockers 
or thread sealant. UNLESS OTHERWISE SPECIFIED, do 
not use supplemental coatings (Paints, greases, or other 
corrosion inhibitors) on threaded fasteners or fastener 
joint interfaces. Generally, such coatings adversely affect 
the fastener torque and the joint clamping force, and may 
damage the fastener. When you install fasteners, use the 
correct tightening sequence and specifications. Following 
these instructions can help you avoid damage to parts 
and systems.
