Description
The 1.6L & 1.8L in-line four cylinder engines have the following features:
•Dual overhead camshafts
• Four valves per cylinder
• Aluminum cylinder head
• Cast iron cylinder block (1.8L Engine)
• Aluminum cylinder block (1.6L Engine)
Operation
The 1.6L & 1.8L engines utilize 4 valve-per-cylinder and a dual overhead camshaft design. The engines use an indi-
vidual coil ignition system. The 1.6L engine uses an aluminum cylinder block, and the 1.8L engine is made of cast
iron. The bearing caps are integrated into the lower cylinder block assembly. An aluminum oil pan bolts to the bottom
of the lower cylinder block. The camshafts are mounted in the cylinder head and act against valve tappets to open
and close the valves. The camshafts are driven off the front of the cylinder head by one timing belt. The belt is driven
by a sprocket that is located on the crankshaft. The piston assembly is an aluminum piston with a cast iron con-
necting rod.
The aluminum cylinder head contains dual overhead camshafts with 4 valve-per-cylinder construction. The valves are
arranged in two in-line banks. The cylinder head incorporates powdered metal valve guides and seats. The cylinder
head is sealed to the block using a multi-layer steel head gasket and retaining bolts.

Lubrication System
The engine lubrication system operates as follows:
•Oil is drawn into the oil pump through the oil pump strainer tube in the sump of the oil pan.
• Oil is pumped through the oil filter on the cylinder block.
• Oil enters the main oil gallery where it is distributed to the crankshaft main journals and to the cylinder head.
• From the main journals, the oil is routed through cross-drilled passages in the crankshaft to lubricate the con-
necting rod bearings. Controlled leakage through the crankshaft main bearings and connecting rod bearings is
slung radially outward to cool and lubricate the cylinder walls as well as the entire connecting rod, piston and
piston ring assembly.
• The engine lubrication system is a full-flow filtration, pressure feed type. The oil pump body is mounted to the
engine block. The pump inner rotor is driven by the crankshaft.
