PRECAUTIONS FOR VEHICLES EQUIPPED WITH A
CATALYTIC CONVERTER
CAUTION: If large amounts of unburned gasoline flow into the converter, it may overheat
and create a fire hazard. To prevent this, observe the following precautions and
explain them to your customer.
1. Use only unleaded gasoline.
2. Avoid prolonged idling.
Avoid running the engine at idle speed for more than 20
minutes.
3. Avoid spark jump test.
(a) Spark jump test only when absolutely necessary. Perform this test as rapidly as pos-
sible.
(b) While testing, never race the engine.
4. Avoid prolonged engine compression measurement.
Engine compression tests must be made as rapidly as possible.
5. Do not run engine when fuel tank is nearly empty.
This may cause the engine to misfire and create an extra
load on the converter.
6. Avoid coasting with ignition turned off and prolonged braking.
7. Do not dispose of used catalyst along with parts contaminated with gasoline or oil.(f) When steam cleaning an engine, protect the distribu-
tor, air filter and VCV from water.
(g) Never use an impact wrench to remove or install tem-
perature switches or temperature sensors.
(h) When checking continuity at the wire connector, insert
the tester probe carefully to prevent terminals from
bending.
(i) When using a vacuum gauge, never force the hose
onto a connector that is too large. Use a step±down
adapter instead. Once the hose has been stretched,
it may leak.
13. Tag hoses before disconnecting them:
(a) When disconnecting vacuum hoses, use tags to iden-
tify how they should be reconnected.
(b) After completing a job, double check that the vacuum
hoses are properly connected. A label under the
hood shows the proper layout.

± INTRODUCTIONPrecautions for Vehicles Equipped with a Catalytic ConverterIN±6

A pressure feeding lubrication system has been adopted to supply oil to the moving parts of this engine.
The lubrication system consists of an oil pan, oil pump, oil filter and other external parts which supply oil
to the moving parts in the engine block The oil circuit is shown in the illustration at the top of the pre-
vious page. Oil from the oil pan is pumped up by the oil pump. After it passes through the oil filter, it is
fed through the various oil holes in the crankshaft and cylinder block. After passing through the cylinder
block and performing its lubricating function, the oil is returned by gravity to the oil pan. A dipstick on the
center left side of the cylinder block is provided to check the oil level.
OIL PUMP
The oil pump pumps up oil from the oil pan and sends it under pressure to the various parts of the en-
gine.
An oil strainer is mounted in front of the inlet to the oil pump. The oil pump itself is a trochoid±type
pump, inside of which is a drive rotor and a driven rotor. 'When the drive rotor rotates, the driven rotor
rotates in the same direction, and since the axis of the driven rotor shaft is different from the center of
the driven rotor, the space between the two rotors is changed as they rotate. Oil is drawn in when the
space is wide and is discharged when the space in narrow.
OIL PRESSURE REGULATOR (RELIEF VALVE)
At high engine speeds, the engine oil supplied by the oil pump exceeds the capacity of the engine to
utilize it.
For that reason, the oil pressure regulator works to prevent an oversupply of oil. During normal oil sup-
ply, a coil spring and valve keep the by±pass closed, but when too much oil is being fed, the pressure
become extremely high, overpowering the force of the spring and opening the valves. This allows the
excess oil to flow through the valve and return to the oil pan.
OIL FILTER
The oil filter is a full flow type filter with a built±in paper filter element, Particles of metal from wear, air-
born dirt, carbon and other impurities can get in the oil during use and could cause accelerated wear or
seizing if allowed to circulate through the engine. The oil filter, integrated into the oil line, removes these
impurities as the oil passes through it. The filter is mounted outside the engine to simplify replacement of
the filter element.
A relief valve is also included ahead of the filter element to relieve the high oil pressure in case the filter
element becomes clogged with impurities. The relief valve opens when the oil pressure overpowers the
force of the spring. Oil passing through the relief valve by±passes the oil filter and flows directly into the
main oil hole in the engine.
