The 3S±FE engine is an in±line 4±cylinder engine with the cylinders numbered 1 ± 2 ± 3 ± 4 from the
front.
The crankshaft is supported by 5 bearing inside the crankcase. These bearing are made of aluminum
alloy.
The crankshaft is integrated with 8 weights for balance. Oil holes are placed in the center of the crank-
shaft to supply oil to the connecting rods, bearing, pistons and other components.
This engine's ignition order is 1 ± 3 ± 4 ± 2. The cylinder head is made of aluminum alloy, with a cross
flow type intake and exhaust layout and with pent±roof type combustion chambers. The spark plugs are
located in the center of the combustion chamber.
The intake manifold has 8 independent long ports and utilizes the inertial supercharging effect to im-
prove engine torque at low and medium speeds.
Exhaust and intake valves are equipped with irregular pitch springs made of special valve spring carbon
steel which are capable of functioning no matter what the engine speed.
The intake side camshaft is driven by a timing belt, and a gear on the intake side camshaft engages with
a gear on the exhaust side camshaft to drive it. The cam journal is supported at 5 places between the
valve lifters of each cylinder and on the front end of the cylinder head. Lubrication of the cam journal and
gear is accomplished by oil being supplied through the oiler port in the center of the camshaft.
Adjustment of the valve clearance is done by means of outer shim type system, in which valve adjusting
shims are located above the valve lifters. This permits replacement of the shims without removal of the
camshafts.
The resin timing belt cover is made of 2 pieces. A service hole is provided in the No. 1 belt cover for ad-
justing the timing belt tension.
Piston are made of high temperature±resistant aluminum alloy, and a depression is built into the piston
head to prevent interference with the valves.
Piston pins are the semi±floating type, with the pins fastened to the connecting rods by pressure fitting,
allowing the pistons and pins to float.
The No. 1 compression ring is made of steel and the No. 2 compression ring is made of cast iron. The oil
ring is made of a combination of steel and stainless steel. The outer diameter of each piston ring is
slightly larger than the diameter of the piston and the flexibility of the rings allows them to hug the cylin-
der walls when they are mounted on the piston rings No. 1 and No. 2 work to prevent gas leakage from
the cylinder and oil ring works to clear oil off the cylinder walls to prevent it from entering the combustion
chambers.
The cylinder block is made of cast iron. It has 4 cylinders which are approximately 2 times the length of
the piston stroke. The top of the cylinders is closed off by the cylinder head and the lower end of the cyl-
inders becomes the crankcase, in which the crankshaft is installed. In .addition, the cylinder block con-
tains a water jacket, through which coolant is pumped to cool the cylinders.
The oil pan is bolted onto the bottom of the cylinder block. The oil pan is an oil reservoir made of
pressed steel shoot. A dividing plate is included inside the oil pan to keep sufficient oil in the bottom of
the pan even when the vehicle is tilted. This dividing plate also prevents the oil from making waves when
the vehicle is topped suddenly and thus shifting the oil away from the oil pump suction pipe.

COMPRESSION CHECK
HINT: If there is lack of power, excessive oil consumption or
poor fuel economy, measure the compression pressure.
1. WARM UP AND STOP ENGINE
Allow the engine to warm up to normal operating tempera-
ture.
2. DISCONNECT COLD START INJECTOR CONNECTOR
3. DISCONNECT DISTRIBUTOR CONNECTOR
4. REMOVE SPARK PLUGS (See page IG±6 or 11)
5. CHECK CYLINDER COMPRESSION PRESSURE
(a) Insert a compression gauge into the spark plug hole.
(b) Fully open the throttle.
(c) While cranking the engine, measure the compression pres-
sure.
HINT: Always use a fully charged battery to obtain engine
speed of 250 rpm or more.
(d) Repeat steps (a) through (c) for each cylinder.
NOTICE: This measurement must be in as short a time
as possible.
Compression pressure:
12.5 kg±cm
2 (178 psi, 1,226 kPa) or more
Minimum pressure:
10.0 kg/cm
2 (142 psi, 981 kPa)
Difference between each cylinder:
1.0 kg/cm
2 (14 psi, 98 kPa) or less
(e) if the cylinder compression in one or more cylinders is low,
pour a small amount of engine oil into the cylinder through
the spark plug hole and repeat steps (a) through (e) for cyl-
inders with low compression.
wIf adding oil helps the compression chances are that the pis-
ton rings and/or cylinder bore are worn or damaged.
wIf pressure stays low, a valve may be sticking or seating is im-
proper, or there may be leakage past the gasket.
