My 94 XJ12 6.0 V12 has been sitting for 2 years and I just did a compression check on it. The Jag manual states it should be 200-240psi. However I have always been told you want all the numbers to be very close. So question is what do you think of my results? I have a 40psi range...250 to 210
1B 250psi 1A 245psi
2B 240psi 2A 225psi
3B 230psi 3A 235psi
4B 240psi 4A 230psi
5B 210psi 5A 220psi
6B 220psi 6A 240psi
1B 250psi 1A 245psi
2B 240psi 2A 225psi
3B 230psi 3A 235psi
4B 240psi 4A 230psi
5B 210psi 5A 220psi
6B 220psi 6A 240psi
