[QUOTE="Viccern, post: 1823079, member: 51336"] All of a sudden (about a month ago), I started noticing a tapping sound when I startup my 2014 Roush Raptor. (144k miles).. from inside it sounded like something was loose in a cupholder or something so I ignored it but after a few trips, I quickly realized it was an engine noise. My problem initially, was by the time I got out to check the noise from outside the cab, it was almost inaudible. With that said, I started doing remote starts and listening and low and behold, it is SUPER loud (not sure if it's always been this loud or if it's gotten worse in the past few weeks) from the outside. The tapping noise quiets down as the engine settles into a lower rpm idle, and that's why initially I didn't hear it when I got out to check. After researching and reading online, the first thing everyone screams is CAM PHASERS, but I was thinking my tapping noise was going away once it started lowering the rpm to idle so I questioned that. There are many online that state that these 6.2L engines just "make that sound" and they deal with it. I refuse to believe what I'm hearing is normal/not harmful. I let the truck run this past weekend until the noise settled down and I popped the hood and I can still hear the tapping from the running engine, just much quieter. I can't tell if it's coming from the cylinder heads or really even if it's only in one spot, but it seems much louder on the passenger side. I checked the plugs/coil wires and everything seems to be seated properly. I've read everything from cam phaser problem, to broken valve spring, to stuck lifter letting oil drain out of the cylinder at shut down that takes a few seconds to recharge once you startup next time and even swapping the type of oil filter you use to reduce "backpressure" , but before I take my daily driver out of service for weeks and potentially let a mechanic go with the "standard" expensive cam phaser replacement that might not solve this, I wanted to throw this out to see if anyone else had this specific problem.
