Just did a compression test last night all cylinders 160+ would a stock 134,000 mile motor have this compression?? From what i understand the motor is stock...the heads still have stock head bolts i want to know if that compression is normal for a 24 yr old higher mileage motor has the motor been ran threw or atleast up top on valvetrain or could it be still OEM... i would think after 100+ thousand miles the rings/cylinder or springs would be a bit on the used side?? i wanted to take motor out and build it because didn't know what was in it but seems like i have pretty good compression, would the compression test show if a cam lobe is worn? just want to make sure the engine is tip top i read horrror story's of wiped cam lobe's.
