I have a 2nd gen JDM b16a in my 98 lx, and when I check my oil it always seems like i'm losing some ( not major) , so I did a compression test ( even thought the place I bought it from said they did one already) So my results are like this: Cyl #1 = 195 Cyl #2 = 200 Cyl #3 = 200 Cyl #4 = 210 It looks like i'm fine, they are all within 28 psi. I didn't do the test with squirting oil into the cylinders because none of my numbers are really low. Becasue in the haynes book it says if any of the tests come out lower then normal add 3 squirts of oil into each cylinder and redo the test. But my question is, in the book its says on the first crank if the compression is low then gradually increases this means you may have worn rings. But how low is low? Like when I did the first crank it went up to 120 then it went up from there and I cranked it 7 times to get the above results. And before i did the compression test I did the vacuum test, and the book says a normal engine at idle should be between 17- 22 hg. Mine at idle stayed at at 22hg, so that test was came out good also.
