ACCURATE MEASUREMENT:

This all-rounder Diesel Engine Compression Test kit covers the vast majority of modern diesel engines fitted to most vehicles.  The 16 piece kit is used to identify worn valves and piston rings.  It includes adaptors for most diesel engines - cars, trucks and tractors, and the easy to read dial gives an accurate measurement of individual cylinder pressures up to a maximum of 70 Bar pressure. 

ENGINE COMPRESSION TESTING:

Engine compression should be checked when an engine is running roughly or is lacking power. Most manufacturers recommend a compression test be performed every time a tune-up is done as part of preventative maintenance.  Consult your vehicle owner's manual for tune-up intervals.

IDENTIFY BAD VALVES/ WORN PISTON RINGS:

By performing a compression test, internal engine malfunctions, such as bad valves, piston rings or excessive carbon buildup, can be detected before they cause irreparable damage.

What is a Compression Test?

A compression test is a mechanical test carried out to assess the working condition of an engine.  It is one of the most frequently performed tests used to determine engine health.  It is essential that it be performed when the following symptoms present themselves: unexplained loss of power, rough idle, engine miss or a puffing noise in induction or exhaust.  It is also recommended that a test be performed after performing an engine tune up.

Quickly Identify Compression Issues:

The compression pressure values should be measured on all cylinders using the compression gauge.  The results should then be compared against eachother and against the manufacturer's specifications for that engine type.

Accurate Compression Measurement:

This procedure will provide a very accurate indication of current engine condition.  If the recorded cylinder pressure value is lower than the expected value indicated by the manufacturer then pressure is escaping out of the combustion chamber. 

What Causes Low Engine Compression?

WORN PISTON RINGS - A common cause of lost compression is the wearing of piston rings over time.   Wearing of rings can prevent a secure seal forming between the ring and cylinder.  Referred to as "Blow-By" the problem occurs when a fraction of the combusting air-fuel mixture, under high pressure, escapes past the pistons and travels along the cylinder walls to the crank case.  This escaped combustion represents lost power as it should have been pressing down against the piston and generating engine power.  It also causes an issue of oil contamination as the byproducts of combustion are entering the crank case and degenerating the engine oil.

CARBON DEPOSIT FORMATION ON INTAKE VALVES - The accumalation of carbon deposits on the valves or valve seats can negatively impact the ability of the valves to close correctly.  An insufficiently closed valve will lose air as it performs the compression stroke resulting in a sub-optimal compression ratio and a loss of engine power.   A knock on effect of this scenario is called "back firing".  This occurs when the air and fuel mixture bypasses the intake valve during combustion.  Also, note that the exhaust valves must be able to close securely to deliver an effective compression ratio.

TIMING CHAIN OR BELT HAS JUMPED - Valve timing has been disrupted. The chain or belt has become worn and loose and it has jumped over the teeth.

PHYSICAL DAMAGE TO THE ENGINE - This can be caused by a number of issues, for example - broken valves, damaged pistons, etc.

BURNED VALVE - The heat generated by combustion has damaged the face of the valve.

TROUBLE WITH THE VALVE - Often caused by adjustments resulting in insufficient valve clearance which prevents the valve from fully closing as designed.  Can also be caused by damage to valve parts, eg: the valve spring, retainer or seal.

RUPTURED HEAD GASKET - Simple, the head gasket has been ruptured.

VALVED SEAT BURNED - The heat caused during combustion has dmaged the cylinder head seat.
