It's my understanding the Cam Position Sensors are at the rear of the engine (two are 2 pin and two are 3 pin). Where on earth are they? And I can't even find the Crank Position Sensor. I understand that the Ecoboost is notorious for timeing chain stretch, but I'd like to replace the Crankshaft Position Sensor and the P0016 Bank 1 Sensor A sensor (intake driver or passenger side?). I hope someone can help, I'm going nuts with this.

I've got 167,000 miles on my XLT screw and have had no problems with mine other than the water in the intercooler. Had the TSB done for it, no correction, so I drilled the hole and have had no more problems with it. I'm running a tune from unleashed, and I have to say I've had a good time with the truck. I didn't buy it for the eco, I bought it for the boost, and it's nice.
I'm running AMSOIL in everything on it, just wondering if the quality of oil has anything to do with it or not?
