2k-2500k Rattle

[Leigh_bullitt]

Guys….being realistic, I love my Mustang. But truthfully, let’s face it, while some come through pretty good, Flat Rock can really use some help in the paint defect and panel alignment department.

Yes but don’t you think all the quirks it has is what makes it a mustang ?.
it’s so raw and unpredictable, that’s why I love it.
Had a Porsche cayman s once and that car bored the hell out of me.

Hmmm
Seems like the rapid ticking noise I have is not the same as the 2k rattle.
I have been noticing the car losing some power but this always happens between start ups and is very intermittent…

I think although not 100% that the noise I’m hearing is coming from the purge valve. It’s like the solenoid is rapid clicking from about 2k revs and only does it when the engine is warm which is when the valve operates.
No error codes because it’s too intermittent with the symptoms and won’t allow time for an error code.

anyway I managed to source a new purge valve for cheap and will see if that is my personal issue.

Hi All
I’ve got the 2k rattle on my 2020 Bullitt. I know exactly what it is as well. The VVT solenoids.
Just wondered if their was ever a TSB or recall to have the ecu reprogrammed like the F150?.

anyone else have the rattle. It’s not a problem apparently just annoying. Anyone had any tunes to change the solenoids or phasers to stop this ?.

thanks

I had posted a SSM a while back for the VCT’s…. I haven’t followed any recent VCT threads only because it’s such a common issue for those to exhibit noise etc and there’s so many threads on this site about them.

Here’s the older link if this is something you’re seeking:

Even if a TSB exists, it’s just a doc with findings to help associate similar diagnosis (and or a possible remedy/fix). It doesn’t mean that whatever is outlined in the TSB IS in fact THE problem. The TSB is just a guide for Techs and Service Centers. Same is true with the SSM’s and GSB’s.

The repair wouldn’t be covered any warranty UNLESS the 3/36 B to B was still in play. I’m not sure if it would be covered under the 5/60 Powertrain UNLESS it’s either specifically included with the engine components provisions in the warranty. They may be considered wear/tear and if that is the case, cost is on the owner to repair.

100% VVT solenoids.
Light throttle in neutral and sounds like marbles in a metal pan.

But HOW do you know this?

Hi
Put my ear

How do you "exactly" know it's the vvt solenoids?

you could be right …
Think I’ve found the noise.
It looks like it’s the PCV making all the noise.
So first I could hear a rattle when idling and it’s the pcv valve which is normal. However I removed the valve and it sounds like a marble in a can of beans. Blocked it off and started the car to 2000rpm and the noise is gone.
So I’ve ordered a new oem valve. Crazy how it can make such a loud rattle noise?.

PCV valve is causing the 2k piston slap noise? Haven't heard that one yet.

Im afraid you've wasted money on a new PCV valve, but I'd love it if I was wrong!

Don’t think I have the 2k rattle.
mine sound more like a marble rattle in a tin can sound or similar to an electrical relay ticking rapidly.
The pcv is definitely causing something with my personal issue though
