These pressures are not great.
What should be compression values?
what are compression values for wet & dry test ?
for BMW E39 - M52B25 motor the compression ratio is 10.5:1 , the values you mentioned are at border line. which engine oil grade is used??
from engine specs available i used this site to determine value
