I just got my vehicle back from the dealership. The history is as follows. Took to dealership in June with cold start rattle and diesel like tick at 94000 miles. 1.5 months later got it back with laundry list of parts replaced.

Got it back and still rattleing. Took it back and 2 weeks later got it back. Engine was smooth.

Started cold start rattleing again with lots of other noise like whirring and ticking. Took it back. Under new tsb had it repaired. Now its silk smooth again. Engine now at 109000 miles. Here is parts list.

The reason Im posting it here is I know a lot of guys have these 2nd Gen Ecoboost engines in their Raptor or F150. This post will help those guys out when they search on Google.

On my Youtube page you can see additional videos of the rattle and this was taken today.

The 2 camphasers replaced appear to be revised.

It's odd that Ford failed to properly address this issue. They've known about it for 15 years, and the Ecoboost engine is no different in this regard. Although, the noise is annoying, I don't believe it leads to failures.


People who count on their fingers should maintain a discreet silence.

Those are the latest numbers for phasers on that engine. There is a TSB regarding start-up noise stating to replace all 4. They have been on backorder forever, sporadically coming in with no rhyme or reason.

Also in case anyone was wondering, Ford is really cracking down on dealers making sure we bill all the OTU (One Time Use) parts on warranty repair orders. That is why you see all the parts on there that probably could have been reused. Ford also revised to procedure for oil leaks involving RTV seals which includes using the ZC-31B wipes and ZC-20 Engine Shampoo and Degreaser.

Did they question the type of oil you were using. Extended warranty?

The Ecoboost is a great engine. Lots of power and fun. Makes just about any car go fast. However it just needs more time to be developed and mature. These boosted engines are still young.

It’s amazing to me that a high production engine such as the Ecoboost has these failures, but not on every one of them. How is it that many of them go high mileage on the OLM with semi-syn oil and no failure? Is it luck of the draw or something more? There’s simply too many of them out, doing whatever duty with no problems. If they were as bad as one reads, Ford would have discontinued the engine long ago. Makes me wonder what causes it, with it being such a happenstance thing.

Good to hear it’s hopefully fixed. I’ll remember this thread if/when mine starts to rattle.

If you look at the part numbers it appears this is the 4th variation of the cam phasers. My engine is now running very smoothly. I think they probably have a handle on it now...lets hope...

Pretty much all of these vehicles will get the rattle eventually. Some have the rattle right now but their vehicle is out of warranty and they choose not to fix it...live with it. The rattle isnt the only thing that happens...a diesel engine like ticking, less power and a whine of sorts.

As pointed out all the parts are backordered now. Some guys waited a month for parts. Thus there is a lot of repairs underway.

I would just go ahead and assume that all trucks without the revised parts will get the rattle eventually.

Now this is a 450 horsepower high output engine. Most engines of this type use 0W40 or 5W40 and thats what I use...or at least a 5W30 on the thicker side. 5W30 is put in there for CAFE not reliability. However that wont stop the rattle. The cam phasers are flawed and it will do it evetnually.
