Cylinder Leak Tester Kit for Gasoline Engine Cylinder Leak Detection

This Cylinder Leak Tester is for detecting a range of engine problems such as worn piston rings or valves, cracks in the cylinder heads or faulty seals. The pressure loss in the cylinder area will be indicated in percentage, the cylinder pressure will be indicated in psi value.

This kit fits for petrol engines with 10mm, 12mm and 14mm spark plugs. It will be delivered to you in a practical carrying case, making it easier for you to use it on the go. Cylinder leak tester Gasoline engine pressure tester Test

This tester can be easily connected to the spark plug hole of the cylinder and allows pressure to be sent to the compression chamber.

A pressure loss greater than 23% indicates a leak, and the noise produced by the air exhaust helps to locate it.

For quick and easy diagnosis of combustion chamber leaks, e.g. on intake and exhaust valves, cylinder head gasket and piston rings

Indicates percentage pressure loss and allows for acoustic monitoring

Suitable for petrol engines with spark plug thread M12 x 1.25 and M14 x 1.25

M12 x 1.25 adapter

M14 x 1.25 adapter

Hose extension with quick coupling

Measuring unit with pneumatic pressure regulator, leak and pressure measurement

Hose adapter

Tutorial:

A leak test is a static type procedure that can help isolate a mechanical component failure.

STEP 1.

With a warm engine, remove all four ignition coils and spark plugs.

2ND STEP.

Place a long, lightweight piece of wire into the number 1 cylinder spark plug hole. Avoid using heavy or sharp objects as this may damage or scratch the top of the piston.

STEP 3.

Using a socket and extension, rotate the crankshaft clockwise until the number 1 piston is at top dead center (TDC)

STEP 4.

Before installing your leak tester, verify that the pressure gauge does NOT contain a one-way Schrader valve.

STEP 5.

Install the hose in the number one cylinder spark plug hole and connect the gauge. Note, if the piston was not at perfect TDC, the crankshaft may spin when pressurized. If this happens, release the air pressure and reset the number 1 piston to TDC.

STEP 6.

Read gauge set. Compare the supply pressure on the left gauge with the amount of air escaping on the right gauge. Severity is the percentage of leakage. The kit that came with your gauge should provide a method to determine this amount. Record the data for each cylinder. Less than 3-5% leakage is acceptable.

STEP 7.

If a leak is present, probe the intake and exhaust channels with a stethoscope. Remove the coolant reservoir cap to check for air bubbles caused by a leaky head gasket and remove the oil filler cap to check for any air leaks at the level piston rings.
