Hey guys,
Curious if you have any insight as to what might cause this noise? 98 auto Limited 3.4 engine. It's very very intermittent. I have only noticed it about 3 or so times over the past 1.5 years. Two times came after a water/mud crossing and the other when power washing the engine bay.
The ticking/tapping noise will happen in park, drive, reverse, or idle. It's pretty loud and is easily heard from the inside. It will get louder with an increase in RPMs in neutral, but goes away at about 3k RPM. Sounds like its coming from the belt or fan, but not sure. It only lasts about anywhere from 5-20 minutes and then goes back to normal.
Heres a short Youtube link of the sound from inside the T4R and outside.
