2.2. Compression check

At obvious reduction of capacity of the engine, increase in the expense of fuel or unstable frequency of idling, check up the following:

      – Ignition system;
      – A compression in engine cylinders;
      – Fuel system.


1. Be convinced that the storage battery is completely charged. If necessary charge the battery.
2. Warm up the engine to working temperature.
3. Remove the central cover from the engine.
4. Disconnect high-voltage wires and ignition coils.
5. Turn out all spark plugs.
6. Insert a compression measuring instrument into an aperture for a candle of 1st cylinder.
7. Ask the assistant to press against the stop a pedal of an accelerator and for some seconds to include a starter.
8. Write down the maximum indication of a measuring instrument of a compression.

9. Similarly check up a compression in other cylinders.

The nominal compression – 1275 кПа, thus a compression difference between cylinders should not exceed 98 кПа.

10. If a compression in one or several cylinders lowered, through an aperture for a candle fill in in the cylinder a small amount of engine oil and repeatedly check up a compression. Write down the maximum indication of a measuring instrument:

      – If the compression has increased, probably, изношенны, the piston, piston rings or a cylinder wall;
      – If the compression still low, means, is worn out or the valve or a valve saddle has burnt through;
      – If the compression lowered in two next cylinders, has probably burnt through a lining or the interfaced surface of a head of the block of cylinders is deformed.
