93 cherokee straight 6 distributor gear stripped for the third time!
I have had my jeep (93 xj 4.0L straight 6 with 150,000 miles) for a little over a year. It ran great for the first 6 months, and died on me one day on the way to work. It turned out the gear that drives the distributor was stripped half way down. I replaced the distributor, cap, rotor, spark plugs and wires. I never could get it to run quite as smooth, lost a touch of power and a couple mpg, but it got me around. This went on for a few more months and it happened again. So I replaced the distributor with a better one and it ran better than ever that day! The next day it did it again before I got off my street. The gear on the camshaft looked ok the first 2 times, but on the third time it definitely was looking worn. I looked into what it would take to replace the camshaft, and it seems that I have to take a good part of the engine apart. Might as well rebuild it? Or else buy a remanufactured engine? Anyone have any experience with this problem? Or advice?
