Cylinder Compression Test (Diesel)

£45.00

Product Information

A compression test is one of the most common methods for determining the mechanical condition of an engine. It should be done when symptoms (engine miss, rough idle, puffing noise in induction or exhaust) point to major engine problems. Measure compression pressures of all cylinders with a compression gauge (fig. 3-76). Then compare them with each other and with the manufacturer's specifications for a new engine. This provides an accurate indication of engine condition.

When gauge pressure is lower than normal, pressure is leaking out of the combustion chamber. Low engine compression can be caused by the following conditions:

  • BLOWN HEAD GASKET(head gasket ruptured).
  • PHYSICAL ENGINE DAMAGE(hole in piston, broken valve, etc.).
  • BURNED VALVED SEAT(cylinder head seat damaged by combustion).
  • BURNED VALVE(valve face damaged by combustion heat).
  • WORN RINGS OR CYLINDERS(part wear that prevents a ring-to-cylinder seal).
  • VALVE TRAIN TROUBLES(valve adjusted with insufficient clearance. This keeps the valve from fully closing. Also, broken valve spring, seal, or retainer).
  • JUMPED TIMING CHAIN OR BELT(loose or worn chain or belt has jumped over teeth, upsetting valve timing).

PLEASE NOTE WHEN HAVING A COMPRESSION TEST DONE SOAK THE GOW PLUGS WITH WD-40 THE DAY BEFORE TO MAKE REMOVAL EASIER

WE WILL NOT BE HELD LIABLE FOR CEASED GLOW PLUG THAT SNAP WHEN TRYING TO REMOVE THEM, AS OVER TIME THEY CAN GET CEASED IN THE ENGINE.
