If things are healthy and as they should be, you should be getting between 160 - 145 , anything lower is weak, if you end up with 3 high and one low then that cylinder is not fireing right
when you say not firing rite what would you mean??
As in if one cylinder is down, then your engine is not running rite
For example, if you got a reading of 155,155,150,155
That would be perfect, they can be a few psi off each other, wont make any difference
or if you got 155,150, 60, 155
You know that cylinder 3 is your problem
cheers lad sound!
The psi its self isnt as important as all the cylinders bein in and around the same
compression test shows only compression, not firing :rolleyes: engine doesnt fire when you do a test.... what it would indicate is either valves or piston rings....Quote:

yeeaaahhhh right :D
Yes any more than a 1 bar difference between cylinders and i would be getting worried:( and make sure to hold the throttle open when cranking cause if you don't you won't get a correct reading.
