Hrm. That seems like it's hanging around, then. I'd take it in to the dealer and see what they say; since you know how to repro the issue, you should be able to give them the steps.

being that the ti-vct partially uses pressurized oil to control the cam timing, it wouldn't surprise me at all if it made some sound when cold. it definitely shouldn't be getting worse though. the noise that most people are reporting may just be a normal byproduct of the ti-vct system in cold conditions(hence why ford isn't "fixing" anything), but it sounds like you have an actual problem.Hi...my name is SM99GT..... and I am victim of engine knock!
I almost feel like I am in a focus group here but its nice to see that I am not the only one with the problem. My car was built Nov 2010 and purchased Dec 2010. I babied it for the first 750 miles only going WOT i think twice, during that period. At around 1000-1100miles I started noticing the knock on cold starts. Now I have 1600 miles and it makes a racket. The conditions upon which mine makes the noise is cold engine (first 5-7 minutes) and almost coast in any gear. IOW, if you take with a certain amount of throttle in gear, as the speed of the car catches up to the amount of throttle input held steady, the internals get to a sort of "equilibrium" state and the top end starts rattling. I am almost positive the issue is not piston slap. Its too high in the motor. It actually sounds like the camshafts are loose or the rockers are loose. Mine has been at the dealer since Monday and so far FMC has not released any public documentation acknowledging such a problem or a fix. I authorized the dealer to pull my valve covers and check clearances on all the parts under there. I asked to re-torque the cam tower caps as a preventitive measure. Upon receiving some pictures from the service manager, it made me wonder if the VCT (specifically the cam phasers) system was the culprit. Here is a pic from the RH head.

I will update here as well as I partake on my journey for a fix.
no one here is a ford engineer. i wouldnt worry about anything till ford says something is wrong. Its its the internet. 90% of it is peoeple thinking they heard something not normal, but its a brand new engine. so who knows whats normal or not
My car has none of these issues. I wonder why some do and some don't
That's a good point. I'm going to wait until Ford, who would have absolutely no motive to skew facts or opinion on the subject, declares to all the world that they have a problem with their engines. In the meantime, all is perfect!

then you shouldn't have bought a car with a 100% brand new drivetrain. your a guinea pig when you buy a first year car, because there will be issues.In other news.. I just hit 4K miles, and I decided to check the oil. It was a quart and 1/2 low, cold, with the car on a level surface. Interesting..
And also, I have a new noise under the hood. It almost sounds like rapidly puffing air or a vacuum leak, but, it sounds like it could be something mechanical, in the top end of the motor, too. Whatever it is, it doesn't sound good. The car is going to the dealership this week. I'm sick of this crap..

they arent going to get away with it, if there is really any issues. I work at a dealer, zero of these cars have been back. Internet is full of bullshit Esp people on mustang forum who think they are engineers
I build race engines, and have done so for 10+ years. I'm not stupid, and it's not bullshit when you have a legitimate problem. My trans has a bearing issue or a lash issue, and, this motor definitely shouldn't have piston slap. It's a cast piston, which has high amounts of silicone, and does not expand a fraction of what a forged piston expands. Modern day engines shouldn't make noise.. The 330hp, 7500rpm engine in my 370z doesn't make noise. And, you know what? If it does, Nissan will take care of it.
I haven't gone to the dealership yet, but, I will not settle for anything less than a fix. Tell me something? If I went to sell this car, tomorrow.. do you think someone would buy it with the noise it's making? Hell no.. I took my buddy for a ride yesterday, and he was freaking out about it/asking me why I haven't taken it in yet. I told him that I didn't want to seem like I was being a pest, and I wanted to take it in once the problem was obvious. Ford had better stand behind this car, or, they'll be buying it back. I know my rights, and I have a good attorney. I plan to be courteous, and to the point with them upfront. If they give me the run-around, I'll do what needs to be done.

I see you're from BTR.. Do you ever come down to No Problem for midnight madness or test & tune?
