I just had the compression checked on my talon. It is as follows 126,127,127,127. They said that stock compression is 130 or so. Is this good compression or should I be worried? It is a 91 tsi awd 66000 miles
Wow only 66000 miles on a 91! I have a 97 with that many!
Your compression sounds ok to me. What you want to look for in those tests is a number that's way off...then there's something wrong with that cylinder.
170 -150psi is ok no lower than 140psi,.you should try it again but this time hold the throttle wide open,and pour a little engine oil down each plug hole and test it again this will tell you if its you rings or you valves causing the low compression,what type of oil do you run in your car.Mine has 220,000km on it and it still has 165-170 psi.
non turbos had a higher compression 170psi for turbo 180psi for N/T
