200 psi 175 psi is below service limit Any more than a difference of 15 psi between max-min cyl is beyond service limit Whats your wet and dry comp values? |

150 is like the best wet 2 are down to 100 dry. cylinders 2 and 4 I think have valve problems. low compress below 100 and don't change when i put some oil around the rings. |

Definitely rebuild time. Id look for a new donk or possibly consider efi. Most rebuilds dont offer good bang for buck or last very long. |
