- The compression of the engine is a parameter of the state of the engine, a good compression indicates an engine in good condition and it will give us all the power for which it was designed.
When the compression of the engine is low we must carry out an engine repair, changing the cylinder head gasket, the valve seals and in many cases the valves, changing the rims of each piston or piston, the pistons on some occasions and finally rectifying the engine block.
Engine compression is done like this:
The spark plug must be removed from the cylinder to be measured (It is necessary to measure the compression in all cylinders)
Disconnect the CKP sensor or optical sensor depending on what the engine has equipped
Connect the pressure tester instead of the spark plug
Crank until the pressure rises as much as possible
The highest value of pressure is the compression of the cylinder
Repeat the procedure in the other cylinders, the pressure measurements should be even and with values greater than 120 PSI.
