So I noticed today that our 06 TB with 4.2 i6 had a knocking sound... I noticed it when my wife was pulling in. Checked the oil and had to add a quart. That did not help obviously. I checked again when it was cold and the same thing.
Here is a link to a video some one posted with the same knocking (but with more pulley noise..)
Any ideas? I keep reading people saying it is the water pump or fan clutch but my ears cannot tell... but that's why I'm asking here. It is a little irregular at idle but becomes faster and more uniform under load. Almost sounds like a little troll is under the hood beating a small pot like a drum.
This vehicle is one of our commuters so I'm trying to keep it running as long as possible.
