When I start my car, I hear a fast, rattling noise for the first couple minutes while the car is running. If I open the hood, the noise seems to be coming from around the distributor cap. It always goes away after driving for a while.
The noise leaves me wondering if perhaps the distributor isn't getting proper lubrication upon start? This noise is new to my car - I've only seen it for a couple weeks now. I'm not sure what else to suspect for this.
Unfortunately, I haven't had a chance to get someone to stand next to it while I rev the engine, as I expect that a distributor noise should change pitch with engine speed. When I get to that, I'll update this.
I stand corrected, the noise is actually more of a whine than a click or a rattle. I still need to get someone to stand next to the car for me while I rev it to see if it changes frequency with engine speed.
