1. safety
WarninG! ensure Health and safety, local authority and general workshop practice regulations are adhered to when using tools.
� do not use tools if threads are damaged. Any defectives must be recified before use, to avoid incorrect readings.
9maintain tools in a good, clean condition for the best and safest performance.9 ensure that a vehicle that has been jacked up, is adequately supported with axle stands.9Wear approved eye protection. A full range of personal safety equipment is available from your sealey stockist.9Wear suitable clothing to avoid snagging. do not wear jewellery and tie back long hair.9ensure any disconnected fuel pipes are plugged to avoid spillage.9ensure that the correct connector is used for the engine being tested.9Always release the pressure from the gauge, before disconnecting the quick release coupling.9Account for all tools and parts being used and do not leave them in or near the engine.9 Always refer to the vehicle manufacturer’s service instructions, or a proprietary manual, to establish the current procedure and data.
2. introduction
up-to-date kit for compression testing on diesel vehicles. contains 17 of the most common dummy glow plugs, covering 29 glow plug types,
33 manufactures and over 500 model/engine varients from 1999 to 2015. Also includes a set of injector adaptors if an alternative method of
testing is required. see instructions on sealey website for complete vehicle applications.

build up during successive strokes, indicates leaking valves or a faulty head gasket (a cracked head could also be the cause).deposits
on the undersides of the valve heads can also cause low compression. if the pressure in any cylinder is considerably lower than the others, introduce a small quantity of clean oil into that cylinder through the access hole, and repeat the test. if the addition of oil
temporarily improves the compression pressure, this indicates that bore or piston wear is responsible for the pressure loss. if there is no
improvement, it suggests that the leakage is around the valves, or a faulty head gasket. A low reading from two adjacent cylinders
is unusually high, the combustion chambers are probably coated with carbon deposits. if this is the case, the cylinder head should be
removed and de-carbonised.
5.2. compression testing.
5.2.1. check the engine oil is at the correct level.
5.2.2. remove all of the glow plugs from the engine.
5.2.4. turn over the engine using the starter motor and observe the gauge, looking for a steady increase in the reading and note the maximum reading obtained. refer to the vehicle/engine manufacturer’s workshop manual for compression data.
5.2.5. Push the re-set Valve (situated under the gauge) to release the pressure. the re-set Valve allows the test to be repeated if required
without disconnecting the tester from the glow plug port.
WarninG! Always release pressure via the re-set Valve Before disconnecting the tester.
5.2.6. disconnect the compression tester from the adaptor and remove the adaptor from the glow plug port. install them into the next
cylinder’s glow plug port and repeat the tests. continue the tests for all of the remaining cylinders in turn.
note: A variation in compression readings between cylinders is often a better indication of engine problems than the individual
values of compression.
