Check engine compression pressure –

Parameters	Specification	Actual	Judgments (OK / NOT OK)
Engine oil pressure	Idle 700 rpm 0.7 kgcm2
	Full load 2100 RPM 2.1 Kgcm2
Compression pressure ( +/- 5 % Variation ) RPM -200 to 300	1 st Cylinder – 22 Bar
	2 nd Cylinder – 22 Bar
	3 rd Cylinder- 22 Bar
	4 th Cylinder – 22 Bar
	5 th Cylinder – 22 Bar
	6 th Cylinder – 22 Bar

Compression Pressure Checking Procedure:

Ensure batteries are completely charged and the engine starter motor is in good operating condition.

Retighten the cylinder head bolts to specified torque. (120NM + Rotate to 90⁰).

Warm up the Engine until the coolant temperature reaches 75⁰ C to 85⁰C.

Remove all high Pressure pipes/lines from the injectors.

Disconnect the fuel shut-off solenoid connection to disable the fuel injection pump (Rotary) or keep stop lever cable in pulled condition.

Remove the 1^st injector and crank the engine for a while to purge the gases from the cylinder.

Install compression gauge adaptor on the injector mounting hole and connect the compression gauge measurement tool.

Crank the engine for 3 seconds and note down the reading of compression gauge after maintaining the 200 – 300 RPM

Repeat the step – 5 for other cylinders

If the reading is low than specified , go for wet compression test

Wet Test: Pour 3 – 5 drops around the piston rings by oil can through injector hole.

Repeat the step from 6-8, if pressure increases on wet test that indicating the leak in cylinders and piston rings. If the compression pressure remains same as Dry test that indicating the valve leaks and head gasket leaks.

Do the above test for all cylinders and note down the readings to analyze the conditions of each cylinder.

Tips:

Look for cylinder variation during the test. If some cylinders have normal pressure readings and one or two have low readings, engine performance is reduced.  If two adjacent cylinders read low, it might point to a blown head gasket between the two cylinders.

By using Compression Gauge:

Check Engine Blow By (Orifice – 5.613 mm)

Problem verification:-

Note:-

Oil to be topped up only if level of oil nears the “Min” mark in the dipstick.

Avoid pouring excessive amount of oil, 2.1 lits is the amount of oil difference between Max & Min marks.

Keep the vehicle under observation for about 1000 kms / 100 Hrs.

Any other observation – Pl give detail :
