So I've had this weird engine noise since new. It didn't happen all the time, and I couldn't really hear it unless I pulled into the garage or was stopped next to a car at the lights with the window open, and only sometimes. I'd stop and restart the car and it was more-or-less gone.
Hard to explain the noise, it wasn't so much a distinct rattle, but like a semi random vibration, almost like a loose bolt rattle, not very loud but enough to notice if your standing close to the wheels. Just a bit more than the usual valve-train/injector clatter. Worst fear was I had a bad/noisy water pump or alternator bearing or something.
So last week, I was doing my yearly front wheel-well deep cleaning where I take the wheel off and hose down the brake dust and polish up the Brembos, shocks and inner liners.
I stuck my hand in the frame space behind the shocks to wipe down and ... WTF ! There's all kinds of little jagged rocks, pebbles and grit in there, this is the spot below:
It's a little pocket area but there is a spot to drain in there. Both sides had some, but the bigger one's were on the driver side. What I couldn't get by hand, I flushed it out with water.
No more noise! I Must have had just the right size rocks to wedge up in there and vibrate a bit at idle, as I can't figure anything stuck in there really making any noticeable noise.
I've never driven the car on gravel roads but yesterday I was in a parking lot with recent pot-hole repairs and a bit of left-over loose paving gravel here and there. I could hear the gravel bouncing around the wheel wells. When I got home, I checked and had a few more rocks stuck in there again. I think maybe the stickier summer rubber might tend to pick up gravel and shoot it around. My Magnum has the exact same frame pocket, but has all seasons and they're empty.
