Preparation For Engine Repair
1. Before cleaning and disassembly, carefully check for
problems that cannot be found after the engine has
been cleaned or disassembled (e.g. oil leaks from
cracked components, gaskets or loose fittings, dam-
aged air cleaner or breather hoses that could cause
cylinder wear, etc.). Make a note of any problems that
you find.
2. Clean or wash the engine exterior thoroughly before
disassembly.
IMPORTANT: Do not spray water on a hot engine.
Injection pump seizure or other failures could re-
sult.
3. Do not disassemble or remove parts that do not
require disassembly.
Cylinder and Cylinder Block Overhaul
Before removing any parts, disassembly or overhaul of
the Peugeot engine, it is very important to understand
the nature and probable cause of the problem that made
an overhaul necessary.
When the engine trouble is caused by worn cylinders,
rings or valves, one or more of the following symptoms
will occur:
1. Low engine power, and a decrease in compression
pressure.
2. Increased fuel consumption.
3. Increased lubricating oil consumption.
4. Poor engine starting.
5. Loud noises in the engine.
It is important to find the cause of the engine failure
before beginning repair. Symptoms 2 and 4 in the above

4. Disassemble the engine in proper order, arranging
the parts the disassembled parts neatly. Apply clean
engine oil to all disassembled parts to prevent rust.
5. Keep the work area clean; dirt causes engine failures.
6. Be very careful when working on fuel system compo-
nents. Cover the work area with clean paper. Store
components of the nozzles or injector pump in clean fuel
oil. Do not allow components to strike each other or
other objects. Wet hands with clean diesel fuel before
handling these parts.
IMPORTANT: Apply clean engine oil to all surfaces
when engine is assembled to prevent marking when
engine is first started.
list can be a result of excessive fuel injection, improper
injection timing, or nozzle and injection pump wear. Poor
starting may be a result of electrical problems. Noises
may be associated with a mechanical part outside the
engine. Excess fuel or oil consumption may be the result
of leaks. (See the Troubleshooting section.)
Another indicator of the need for an overhaul is oil
consumption. Make sure the engine does not leak oil.
when the oil consumption between the oil change main-
tenance interval is approximately 1-1/2 times normal
(150%), engine overhaul should be considered.
With a good knowledge of how the engine operates,
access to maintenance and compression test records,
and information in the Troubleshooting section of this
chapter, unnecessary disassembly and inspection can
be eliminated.
