This is a good sign. Maybe these engines just have a weird extended break in period.

IMHO this rattle seems pretty prevalent and I think by now we’d know if this rattle caused major damage.

I know some guys have been unfortunate and suffered major damage to their engines but it’s hard to point to the rattle as the exclusive cause of the damage.

I’m happy this thread exists and we’re sharing our experiences and ideas. I know reading these posts has given me much more piece of mind.
One thing to always remember, is that when you start your car cold, never put your foot down until it's warmed up. I never go over 2k rpm until the temps are all normal. I have noticed in my car the rattle seems to be loudest when VERY cold. As soon as the oil warms up, it gets much quieter. However, it's not piston slap though, because the block in 3rd Gen grows much more than the previous Gens. That means if it was piston slap, it would get worse as the cylinders grow after warmup. My guess it is has a lot to do with the oil temp. Once it warms up and thins out, it provides the proper pressure and flow to the Phasors, HPFP, chain tensioners, etc.

I agree completely. It’s not a good idea to beat on any cold engine like a rented mule. I’ve noticed on mine that the rattle is definitely more prevalent when cold. After everything reaches operating temperature then it disappears 90%. Once in a while during driving it will remind you it’s still there but mostly it’s super quiet.

I have an upcoming road trip from Chicago to Atlanta and the car will spend a couple days right around that magic “rattle RPM” range while cruising and I’m very curious if that will make any difference

Even better, go from idle to 1,200, but VERY GRADUALLY, not abruptly blipping the throttle like you were doing. Then you could rev it to 2K to 2.2K, to see how loud the 2K rattle is like that. Then go for a drive with open windows, exhaust in quiet, and radio off, and see how it compares. Then give us your report :D.

Hmm, I can’t tell what I’m supposed to be looking for. Tried it in Quiet mode, tried it idle. That rattling sound I posted is only evident when “pumping” the gas pedal between 800-1500.

I think there is a TSB about a similar noise you're describing. Can't seem to find it right now - maybe @Cobra Jet can chime in.

Alright since I can’t tell, maybe you internet gurus can. I didn’t hear that metalic rattle from last video and most noises appear normal, at least to me.

one video is just engine idling and the other is holding it between 2-2.2k twice

Doesn't sound bad in those two videos while at a constant idle, or constant 2-2.2K RPM. If it's making that rattling noise only when revving up and down, it could be something like the chain tensioners not keeping the timing chains totally tight during acceleration and deceleration of the chains - just a theory.

I can't hear anything wrong with that engine.

I’ve had the 2k rattle since somewhere around 1-2k miles, now at 9k, hasn’t changed a bit. Drove me nuts for a while, but now I don’t even care anymore, especially after everything I’ve read here. I pitched out for the Ford ESP service contract 6 years 125k miles, so whatever happens, happens. You don’t have to turn up the radio all that much either to drown it out completely. I just hope someday someone solves the mystery... My personal guess is either the clutch or tranny.

My thing is, how does this not happen when the car is new? Does the block grow differently at 8K miles now that the rattle just started? I can believe it's better for the car to warm up before getting on it. When a problem "develops" I call it a problem and not normal. It does seem to get quieter when warm, but there are cars out there that do not have the problem. Mine used to be one of them. Just frustrated. Mine sounds like playing cards in the spokes of a bicycle tire. (Showing my age...)
