Hello I have a 98 4.0L 4x4.I had been hearing some noise that sounded like some belt or tensioner noise.After inspecting the engine some more i found that the noise was comeing from the cam position sensor.I ordered a new sensor and syncro shaft.I removed the upper intake and found that the sensor had a hole in it and the trigger vane was gone from the shaft.When i went to mark the syncro shaft i found that the shaft had moved and the sensor connector was stuck against the bank#2 head.So my problem is this i have no idea where the shaft is ment to be in and I can not find any timing marks on the balancer for TDC.The chilton book that i have states that it need to be at 10 degres ATDC.Do you guys please help me thanks.
