I've read where it is recommended to switch to billet steel gears if you're upping the redline or doing a power adder but I believe we should make it a "best practice" on any Coyote.
Mine is a 14 Track Pack and the motor is absolutely bone stock and you got it - I lost the pump drive gears last week. I've only got 100k kilometers on the car or 60,000 miles and it gets a fresh load of Mobil 1 synth well before it's due. Last week it started behaving oddly, low rev lost its "snap", it was not pulling at part throttle like it used to and then as the needle swept by 3500 or so it suddenly woke up, felt like back in the day when you kicked the secondaries open on a carb motor. I can only assume it was not getting the pressure it needed until that point and then the cams moved properly although the gauge said "oil pressure normal" and then last Wednesday at 2,000 rpm cruise it lost pressure and spun a bearing.
Crappy powdered metal OEM pump drive gears came apart, the research I read said that as low as 5500 rpm they start vibrating ( harmonics they called it) and they fail.
Now my 'Yote sounds like a steel drum band - rebuild time - don't wait, get them done before yours joins the band.
