RR with 300 miles cold start rattle.

[Raptor_Mike]

Hello all,

My 2025 RR cold start. Does this sound like the phasers or is this normal?

Thank you

I made a similar post when I first bought mine. I brought it to the dealer for em to have a listen and it is the high pressure fuel pump for a direct inject engine making that tick.

...Ford even puts a cover over it to try and quiet it down.

I guess I hear a slight "rattle", Keep your eye on it but don't worry it is under warranty.

Here is what one sounds like with a confirmed failed cam phaser, sounds much rougher.

Sounds totally normal to me

Normal. Phasers would last longer I believe.

You'll get a rattle for a few seconds on start up until the oil pressure comes up. If it continues longer than, especially when revving up the engine, that could be a problem.
I hear the same thing on my XLT Ranger 2.7L.
