Are you sure you did the test correctly? I've seen countless threads of people posting compression test results that sounded terrible only to find out later that they didn't do it right...you said it yourself, everything seems fine....

why did you test it in the first place are you burning oil or something. If all the cylinders are about the same like that it might not be that noticeable in terms of driveability. But i agree with ando it is unlikely that all of them are that bad. How long did you crank the engine over for on each one. Did you leave the spark plugs in on the cylinders you weren't testing.

maybe the tester is not working properly, but if the result's stay within 10 to 15 % from eachother it's a good sign. Last time I did a compression test on my b16a I got 210 all across.

yea i think its the gauge because we did it on 3 different cars to make sure that its the gauge and they all show up to 120 only so i will go back and return the tester to peb boys and get a different

the reason i did the test is because it feels like the car lost power to me and i am getting some ctr cams so i was wanting to make sure the car runs good if i am going to install them

make sure you re adjust your valve's when installing the cam's, I have the same cam's in my lsv and it sure made a difference up top. good luck

anything under 135psi needs to be serviced and cylinder walls could be damaged.
