3k RPM Engine Rattle - unresolved

[ShadowsPapa]

does the noise change at all?

Those last two words are the key........IMO, anyway.

Is the rattle noise consistent in neutral only? What happens when you push the clutch in does the noise change at all?

Sadly, no. Clutch in, out, slowly pressing it in, neutral, stopped or driving - nothing. I even tried pushing the clutch pedal left/right to see if it’s wiggling.

Nothing yet. They are looking into it but don’t know what to look for. Mine happens almost every time I drive now. It’s frustrating.

Dealership called and they want to replace the right side oil control valve and phaser. I’m not fully confident it’s going to resolve the issue and I’m not a fan of dismantling parts of the engine so often given we just did the left side and clutch:flywheel but it’s worth a try. I’ll let you know next week if the issue is resolved.

I am wondering if it could be the shift cables resonating against the heat shield

shouldn't have to remove the same parts, and, there have been phaser rattle issues reported on these and other make engines.

Dealership replaced right side phasers and oil control valve and issue is still there. So, replacing both oil control valves and all phasers does nothing for this issue.

Any luck with you guys?

If it will happen in neutral when not moving, you and a friend can try to locate the source with one of you pressing the accelerator and the other crawling around listening and pushing/wedging/hitting on stuff. It is possible the shop jumped to conclusions and started replacing parts without actually locating the source of the sound. Even if you hear it up top, crawl underneath and listen, poke, and prod around there too. Sounds carry and can be hard to isolate. For example, my wife's minivan had a nasty rattle when cold that sounded like it was coming from somewhere up on the engine but it turned out to be a loose exhaust hangar clamp underneath the engine. I don't much care for crawling around underneath when a vehicle is running. I imagine it won't be fun doing it at 3K rpm.

Fixed.
