What did you take off when you replaced the valve covers? It has to be one of the pieces you removed and reinstalled.

Got a pic of the valve covers?

Sounds like it could be a spark plug wire.

I had something possibly like the moan you had. I tried everything without success until I replaced the EGR. Check all lines to it to be sure there are no leaks. If they are ok, then see if you can borrow one from someone else to try before spending $60 for a new one. And I found you can't really check the EGR to see if it is ok. I think that is where the moan comes from. Maybe the diaphragm flutters or leaks to make the noise. Then again it could be a spark plug wire. Don't know, just guessing.
