I recently acquired a high mileage, non-running, 1995 4x4 Ranger with the 3.0 engine. After troubleshooting a fuel issue I finally got the truck to start and was greeted with a check engine light and code P0340. No problem I thought, probably a bad wire or sensor. But upon inspection of the sensor I was greeted with the below horror! Further reading indicates when a cam position sensor is damaged this badly it is usually due to a worn out bushing in the synchroshaft which drives the oil pump... So my questions to the hive mind is, how would I check the engine for oil starvation damage and how does one replace the cam synchronizer when you are unable to mark the position of the "flag"?

Damage to the cam synchronizer.
