Anybody else have this knock???
I just got the first oil change on my 2014 GT. I noticed that now during warm startups it will knock and then go away. I brought it back to Ford and they said that the 5.4L do the same thing. The tech explained that with the variable cam timing, it will lose oil pressure causing a "dry start". They said it would be fine, but it doesnt seem right to me with only 4k miles on the engine. I do have some mods and before the oil change warm startups were no problem. I am wondering if anyone else has this issue and if so what can be done about it?
I have an Airaid CAI with a 89 octance Bama performance tune and Pypes cat-back.
Thanks!

That's a first hearing about this on my end. Are you experiencing this when you're set back to stock? Let me know how I can help or feel free to shoot Bama a call directly at 888.226.9764 if you would like to speak with a tuner directly!

Welcome to the forum! You are also always welcome to get a second opinion at a different Ford Dealer. If you chose to do so, let me know so I can escalate this to the customer service manager for your area.

I will warm it up and return it to stock and see if it still happens. Im hoping it is something that can be adjusted. If not, how picky are most dealers about SCT tunes? The guys I spoke to at mine didn't care, but then again look at the answer they gave me lol..

I never really paid attention to oil filters cause I never had to. What exactly am I looking for? Or if you have an opinion what has worked the best for the Coyotes?

My car has had Motorcraft. K&N, and Purolator on it. No noticeable differences. I have a hard time thinking the filter is to blame.

From my understanding the anti drain back valve could've failed. So changing the oil filter is a cheap way to diagnose and even fix the problem. If I do this and the knock still occurs then I'll bring it in. If not then I know that what ever the dealership used is crap. From everyone's response and what I've read online this does seem to be the likely problem.
