Well, I got the belts replaced, which made the "vavle noise" go away.
The dealer told me the valve noise was just belt noise. I still get some
valve chatter, but I hear that is typical of pre-magnum 6er's. I'm also still
getting the fwa,fwa,fwa. It almost sounds like there is something rubbing
on something else. I lost some power, but I think it may be the engine
showing it's age. The afore mentioned "fwa" is pretty loud (about as loud
as the Flowmaster)... hope it's not what you're having =( sorry about the
Dak man. Hope she's up and running soon! Thanks for the advice. I'll post
to the list my results for future reference. =)

Hopefully your Fwa, Fwa Fwa noise isn't as bad as mine. I just found a
burnt valve in my Dakota. I put new heads on the truck last year after
slapping a valve. After that, the truck never really seemed to have the
power it had before. Last week the truck starting running really rough,
and
had a bad skip. First I checked the easy stuff. I pulled the plugs and
found one that was really fouled out. The same cylinder that had
slapped
the valve last year. I put new plugs in and no improvement. Then I
change
Cap, Rotor, wires etc. Finally I did a compression test. Only 10 lbs.. in
that cylinder. I figured that the piston had a hole since I had replaced
the heads 20,000 miles ago. I pulled the head and found the exhaust
valve
had a half inch V shaped chip missing from the edge. I pulled the valve
out
of the head. First off, it looks like the valve never seated from the
start. It also had a very slight bend. I had the head checked and it looks
like the seat was ground crooked when the head was originally
machined.
Hopefully I'll have all the pieces back together this weekend.
