IF VEHICLE IS EQUIPPED WITH MOBILE
RADIO SYSTEM (HAM, CB, ETC.)
The ECU has been designed so that it will not be affected ±by out-
side interference.
However, if your vehicle is equipped with a CB radio transceiver,
etc. (even one with about 10 W output), it may, at times, have an
affect upon ECU operation, especially if the antenna and feeder are
installed nearby.
Therefore, observe the following precautions:
1. Install the antenna as far as possible from the ECU. The
ECU is located under the radio so the antenna should be installed
at the rear side of the vehicle.
2. Keep the antenna feeder as far away as possible from the
ECU wires ± at least 20 cm (7.87 in.) ± and, especially, do not wind
them together.
3. Check that the feeder and antenna are properly adjusted.
4. Do not equip your± vehicle with a powerful mobile radio system.
5. Do not open the cover or the case of the ECU unless absolutely nec-
essary. (If the IC terminals are touched, the IC
may be destroyed by static electricity.)
AIR INDUCTION SYSTEM
1. Separation of the engine oil dipstick, oil filler cap, PCV hose,
etc. may cause the engine to run out¿¿ tune.
2. Disconnection, looseness or cracks in the parts of the air
induction system between the throttle body and cylinder
head will allow air suction and cause the engine to run out of tune.
ELECTRONIC CONTROL SYSTEM
1. Before removing EFI wiring connectors, terminals, etc., first discon-
nect the power by either turning the ignition switch
OFF or disconnecting the battery terminals.
2. When installing the battery, be especially careful not to
incorrectly connect the positive (+) and negative (±) cables.
3. Do not permit parts to receive a severe impact during removal or
installation. Handle all EFI parts carefully, especially the ECU.
4. Do not be careless during troubleshooting as there are numerous
transistor circuits and even slight terminal contact can cause fur-
ther troubles.
5. Do not open the ECU cover.
6. When inspecting during rainy weather, take care to prevent
entry of water. Also, when washing the engine compartment, pre-
vent water from getting on the ER parts and wiring connectors.
7. Parts should be replaced as an assembly.

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.
