Noisy running or engine noise
Engine components
- Pistons
- Piston rings
- Connecting rod big end,
main bearing or thrust
bearing journals
- Connecting rods bent or
damaged.
CHECK the engine compon-
ents for wear or damage. Make
sure all components are within
specification. INSTALL new
components as necessary.
Engine - Oil Leaks
NOTE: Before installing new gaskets or seals, make
sure that the fault is clearly established.
If the oil leak cannot be identified clearly by a visual
inspection, carry out an ultraviolet
(UV) test:
Ultraviolet (UV) Testing
1. Clean the engine and transmission with a
suitable cleaning fluid.
2. Pour the UV-test fluid in accordance with the
quantity specified by the manufacturer through
the oil filler neck into the engine and install the
oil filler cap.
A WARN1NG:Vehicles with manual transaxle,
shift the transaxle into Neutral. Failure to
follow this instruction may result in
personal injury.
3. Start the engine and let it run for about five
minutes. 4.
Switch off the engine.
N0TE:lf no leak can be found, road test the vehicle
under various loads and check the engine for leaks
again.
5. Check the engine for oil leaks using a suitable
UV lamp.
'
6. Rectify any leaks found and check the engine
for oil leaks.
Measure the compression pressure
N0TE:The powertrain control module (PCM)
receives an error message when the fuel pump
relay is removed or electrical components are
disconnected. This error message must be deleted
from the fault memory using WDS after completing
the compression test.
(' ,
'I N0TE:Valve clearance must be set correctly before
performing a compression test. Make sure the
engine is at the normal operating temperature.
