Engine rattle/noise at start up

[OPT PRIME]

You guys won't believe this, but my Raptor has STOPPED rattling on start-up after extended sits. Even the timing chain noise during light throttle blips is gone.

I have no idea....

Hmm, this leads credence to 'it isn't a problem sometimes', which is what a decent amount of techs say. Such a strange issue, to say the least.

I have done nothing to fix my rattle other than documenting it with the dealership. Going on 21k miles since it started. It is very erratic now. Some days it does not rattle at all and on other days it does it every start. Truck still runs strong with no other issues.

I have noticed that it rattles less on a full tank of gas. Strange! I put Mobil 1 in it the last oil change with an 820 filter and seems to have helped. Could just be the fresh oil. Tech at dealership said he has seen many trucks with the rattle and reccomended changing the oil at 5k and to ignore the dummy light. This may not make any difference at all but what the hell.


I still think Ford has no idea what is causing the rattle. My friend has a new Navigator with the same engine and guess what, it rattles! Got the ESP, so if the motor blows, Ford will give me a new one. I still love my Ford Rattler!

Well I read this entire thread and wish I had seen this before I got my 17 last week.........it has the rattle. Has 31K on it and I am the 3rd owner. Not sure why neither one of the first owners took the truck in for it? But anyways, I am stuck with it now. I literally had just got it back for sync 3 issue and broken panoroof too! I don't want to take it just for them to fix it with parts that will fail again......

Man that sucks. Better get it in there before you get too many more miles on it since you are getting close to your warranty period.

The 5 year 60k should cover it. My bumper to bumper is close.

You may want to check that just to be safe. I was told this was only covered under 3/36k.

No you weren’t. You don’t even own a Raptor.

Good luck. Might be time for her to have a fourth owner...
