If the engine runs poorly or intermittently, perform a compression test. Regularly carrying out this check will allow you to prevent the occurrence of malfunctions in advance.
To carry out the test, you will need a tester designed for diesel engines. Connect the tester to the adapter and screw the adapter into the glow plug or injector hole.
The engine must be warm, the battery charged, the spark plugs and injectors unscrewed, the shut-off valve and fuel block wires disconnected.
The pressure in all cylinders must be the same. A difference of more than 0.5 bar between any two cylinders indicates a malfunction. In a healthy engine, pressure should build up quickly. Low pressure on the first stroke, gradually increasing on subsequent strokes, indicates that the piston rings are worn. Low first stroke pressure that does not build up on subsequent strokes indicates a valve leak or blown head gasket. Deposits on the bottom of the valves can also cause low compression. Low pressure in two adjacent cylinders almost always means that a head gasket is blown between them.
If you have any difficulties during the verification, contact the experts.
