Rattle starting at 2K miles

[mattsanfran]

I have a 2025 DH, now 6K miles, has had the rattle at 2k the whole time. Is there anything to do about it? Sounds like a diesel truck

Both my manual s550 that I had and manual s650 I have do it/did it. It goes away after the car is warmed up. Not really sure what the chatter is.

I’m surprised you haven’t gotten tons of answers on the 2000 RPM rattle. It’s normal. Ford has issued some bulletin on this, although I can’t quote the bulletin. I do know that the rattle is caused by some kind of lack of lubrication regarding variable cam timing. I don’t like it, but it’s normal.

Its been a thing since the Gen 3 Coyote. Some will say even before that. It definitely seems more prevalent on manual cars. I had it pretty bad on my Mach 1. It drove me nuts. Nothing has been confirmed, but its most likely noise from the Cam Phasers or the DI pump. Ford says its normal.

If you think its abnormal bring in to dealership. Have them check it maybe its not the normal 2k rattle? Maybe something else is wrong. It couldn't hurt to ask them to listen and check it. Plus it might give you some peace of mind.

Since Gen1. This is the Phaser rattle. Louder when cold, then quiets down as oil gets up there. Funny story a few of us a couple years ago tested moving the cam angles around by manipulating the VCT drive scenarios and wouldnt you know it the noise followed the cam angle changes. Ford has known about this since 2011 and offered a PCM update to "quiet them down"
back in 2011/12. The younger folks or newer gen owners dont ever hear this tribal knowledge from folks that have been around coyotes since the old days.

But you are hearing the phasers moving around. Some louder than others. And the next coyote noise you might hear is piston slap at idle. Like a womp womp womp sound through the firewall. No more sound tube on these, so people stopped complaining about that one a while back.

And the final coyote noise is the BBQ tick. Heard mainly under the engine at idle, its intermittent sound like a hot bbq lid popping from heat expansion. Thats the sound reference. A can after every oil change of the Liquimoly Ceratec stops it almost instantly and will keep it gone until the next oil change. Add one after any oil change.

have you heard of any harm caused by additives? I was thinking on doing Ceratec to quiet it down but of course Ford doesn’t recommend using any additives.

No people been using Ceratec for 15 years on these cars religiously. I've put it in every sports car I own since I found out about it in 2011. Thats probably 40 cars over hundreds of thousands of miles. And if you google that stuff, people are using it in all brands and types of cars now. It really does work. That extra moly is very good for the engine.

One thing I will tell you tho is I wait to do it until after the first oil change or maybe around 2500 miles. I want a clean break in before I put anything like that in there. Nothing to prevent the rings from seating and wearing in completely.

And for me, I break in cars very hard. Ive seen time and time again less to no oil consumption on cars that are dyno broken in or broken in very hard on the street. None of that pussyfooting around driving. Most of my cars are performance tuned by 100 miles on the ODO anyway and doing WOT dyno pulls and big street pulls, so they always seem to make top power compared to the average and seem to drink no oil. No coyote I've ever owned needed a catch can or ever had to have oil added.

Now is that good if I want to DD it to 100k miles, probably not but i dont keep a car past 15-20k miles in most cases. So take all that with a grain of salt.

More and more I’m convinced people subconsciously want EV’s, that don’t make mechanical noises.

I think they just want a perfect new car. I know I do. Every car I've ever bought new needed something. A scratch buffed out, or an alignment or had some weird noise or something that needed to be fixed or added. New cars these days are mistreated from the minute they leave the factory.

They sit for days or weeks at factory lots, then in rail yard or trucking distro lots. Man handled by several people in transport all the way to the dealer lot. Then man handled again by some $15 an hour porter. Then beaten by service guys doing PDI, salesman on test drives and more porters when they move them around, or go to gas them or watch them for you. You get a used car by the time it gets to you no matter how low the miles. And thats just physical condition issues. Think about all the reving and beating on cars that happens with 4, 5 or 6 miles on the odo. It makes me insane to think about. But I have OCD and are a perfectionist when it comes to the condition of my cars. Thats just me though.

This exactly. With the substantial rises in costs and no wage increases to match, I don’t blame anyone for wanting perfection out of what they spend their hard earned money on. I’m just like you, meticulous about my car, down to every detail. It makes me sad to think about what my cars may have gone through before they got to me.

Ceratec is just fine and eliminates the tick.

One other thing you can try is to change the pcv valve to the gt500 pcv. Its a better performance one and others have changed it out if their pcv is the rattle. On some the pcv rattles and clacks. Mine has it but its not to noticeable. Here is a link for the pcv.
