hey guys kinda need your help on this, this rattle noise appeared about a week ago and it sounds like a loose screw is bouncing around inside the cylinder, identical sound to if you take a rock and put it in an empty tin can and shake it.
This noise appears on cold starts and it stays there for a few minutes until it reaches optimal operating temperature.
It is an inconsistent sound (it doesn't have a rhythm)
I haven't been able to pin point exactly where it's coming from but it's loud enough that you can hear it from about 100 feet away.
Engine oil is full
5w-20 full syn. (only burns a quart every 3k miles)
Coolant is still full, it's not mixing.
Drives fine (though I feel a little lack of torque on take offs now)
No CEL or any symptoms so far just the noise.
I couldnt find a single video on YouTube that closely resembles this noise and I'm kinda on the fence on what this might be...
Any clues?
This is not a cam phaser tick as I have that consistent tick cold or hot and it's there right beside this rattle noise on cold starts
