low compression in #2 only showing 89 lbs
Totally rebuilt 258 with 4.0l head. Did a general compression test yesterday. All clylinders reported 170 bs, except #2 which showed only 89 lbs. On a recheck the same results. Took the oil can and added a little oil, ran the test again. Exactly the same pressure. About 10,000 miles on the engine. What could be the cause?
