Compression Test

[xx_civic_si_xx]

Sup guys, I plan on doing a compression test on my k20a3 but i got a question. How and what do I have to turn off first in order to run the test??

just did this the other day... Make sure car is off, unplug fuel injectors and remove coils and spark plugs.... turn the car on and it will shut off once all fuel in motor is gone... then plug the compression in the cylinder and open the throttle fully and crank the engine 2-4 times but make sure u do the same exact cranks for each cylinder such as dont crank the engine on one cylinder for 5 secs and then 2 secs on another cylinder, make sure they are the same length.... yes i suck at describing but hope this helps

On my friends motor cycle all he had to do was take out the plugs and turn it over... no idea how it works exactly for cars tho.
Lol its so much simpler on motor cycles.... probably because they are well equipped with their cute little sowing machines
