TABLE OF CONTENTS If the reported fault is excessive use of engine oil proceed as follows.
Question the customer to find out how much oil is being used.
Examine the vehicle for oil leaks and blue smoke from the exhaust.
For example, oil may be leaking from a gasket or seal if no leaks are found the engine may be burning the oil.
A compression test, if the results were acceptable, would indicate a leak to be the most likely fault. Clean down the engine and run for a while, the leak might show up.
For example change the gasket or seals.
Run a thorough inspection of vehicle systems, particularly those associated with the engine. Double check that the fault has been rectified and that you have not caused any other problems.
| Note | You should always refer to the manufacturer's instructions appropriate to the equipment you are using. |
With this device the spark plugs are removed and the tester screwed or held in to each spark plug hole in turn. The engine is cranked over by the starter and the gauge will read the compression or pressure of each cylinder.
A leakage tester uses compressed air to pressurise each cylinder in turn by a fitting to the spark plug hole. The cylinder under test is set to TDC compression. The percentage of air leaking out and where it is leaking from helps you determine the engine...
