just got doing a compression check on my 94 civic ex with d16z6. it went #4 155 #3 150 #2 152 #1 152. now does that sound low? the consistency is really good but i thought the psi sounded a little low. i have heard there is different ways of doing it also. i pulled the dizzy and the engine was cold. throttle was closed. and the tester was one you screwed into the spark plug hole. i have also heard of people doing leakdown test. how do you do one? thanks for the help

Sounds like you have a good motor.

I usually do my compression test when the motor is warmed up. I think your numbers are in the 150s (which is still good) because its cold. But the key is that its within 5 of each other, which is <FONT SIZE="3">EXTREMELY</FONT> good!

Looks prety perfect, and usually the 3rd cylinder is the one that is usually lowest.

null.

you can also squirt some oil in there, it will up the compression when testing it but nonetheless the results are certainly GOOD

welp thats good to hear. my motor has almost 140,000 miles on it. so i figured i would see how she is doing. but another thing is i just got a valve adjustment like the day before would that make a difference? or is the valve adjustment got to do with the leakdown test? thanks for the comments tho
