I'm measuring the compression on a 91 ranger. I've been looking for spec information for this engine to compare the readings to, and it's been surprisingly difficult to find. All I've found just states what the cylinders should read in comparison to one another, not the general psi range the cylinders should be within individually. I've been looking online and in a Chilton manual and found nothing. I'm used to working on old honda motorcycles, where these values are clearly given as an acceptable range (i.e 160-190 psi), alongside what the cylinders should read in relation to one another. Am I missing something here? Is the individual compression of each cylinder not relevant for some reason?
