Default f22b1 compression test

cyl1=70 cyl2=140 cyl3=65 cyl4=140

Wondering if it's normal for cylinders to go out in this order or not? I havn't lost any oil since i've had the car so im thinking it's just all blowby on the piston rings. Could the rings of vibrated towards each others gaps? Perhaps if i considered the firing order it'd make more sense. How much power could i expect to lose from having this compression?

cyl 1 and 3 are really low. Sounds like you need a new hone..but your rings could be bad too.
You are prob. running around on 100-120hp most likely

Compression isn't as important as the consistency. I'd be more worried about that.
