How to do a compression test?

[manybrews]

remove ALL the spark plugs.
disable the fuel in some way.
Install compression gauge.
If the intake is still on the car, have someone hold the throttle wide open.
Crank the car about 6 revolutions.
repeat for each cylinder.



but if you dont know how to do one, id suggest not doing it. You can screw things up if you dont disassemble / reassemble it all correctly.
