I've recently been noticing a very annoying ticking/rattling/knocking/tapping sound coming from my engine area. It's become more noticeable when it's cold, and seems to sometimes mitigate as the engine warms up, or if it's warmer outside. It is not any trim pieces from what I can tell. I can only best describe the sound as that old school telegraph machine relaying a morse code-- completely irregular, but in quick succession and constant. If you tap a single finger quickly on your desk, repeatedly and consistently, it sounds quite like that.
The sound is most present in "drive", with a foot on the brake. Shifting into park, nuetral, and reverse either completely eliminates it, or reduces the volume of the tapping by about 90%. I'm on my third vehicle with this pentastar engine, and this is not the usual noisy chatter the engine makes at idle. It's definitely not as intended. My guess is a loose rocker arm. My only hesitation is that because it goes away by shifting into a different gear, the sound might be coming from somewhere else.
S0-- if it's something not inside the engine, and you help me diagnose it, I'll paypal you some money! Any suggestions?
