After past problem upon purchasing the jeep and rebuilding the engine (never touched the cam) it's been about 10k miles. I was driving down the road and lost oil pressure and long story short after dropping oil panel and finding metal shavings, I checked main and rod bearing all were good. I then discovered the teeth for the oil pump were sheared off. Has anyone ever heard of this as they are literally gone. What else should I look into replacing and with what upgrades so this doesn't continue to happen.
