Engine compression numbers
Would you guys shy away from a rebuild with 500 miles on it with compression of 92 on each rotor? I know thats low however do you think the seals are fully seated? Will that number go up with more miles?
Thx

i would find out the circumstances of the comp check. was the car warm or cold, throttle open or closed, and what cranking rpm. a cold car will lead to higher readings, throttle closed will lead to lower readings, and 250 is the ideal cranking rpm, lower rpm will lead to lower readings.
