Hi  Gang,

Did a run down to Reading PA, this weekend. Took my 1990 350 SDL  w/252K on
the clock.  After about 2 hours of high-speed interstate  driving, (75-80
mph) I started to smell something burning......smelled like  a combination
of plastic, rubber and/oil burning.  Not really strong,  but SWMBO and I
both picks up on it.  Checked for obvious leaks, fluid  levels, belt, tires,
etc, found nothing unusual.  If I keep the speed  down to 60-70...no smell,
so I just drove a little slower, made our  destination and back home again.
Unloading the car back home, I noticed the  smell in the trunk, but not the
cabin of the car!  Any clues as to  where to look or what might be wrong?
I know it's a vague description, but  I have to start somewhere!

This is/was the first long trip I've taken  in a while with this car, so
maybe it's a problem I've had for a  while.  The only stuff I recently did
was replace a bad glow  plug,  a breather hose and the Boost Pressure
Control Hose on the  turbo. (Should that one be something other than generic
fuel line  hose?)

On a positive note, on the way home, I drove 164 miles on 5.5  gal of diesel
for 29.82 MPG.  Can't hate  that.......



Angelo,
 
You have a hole in the top of your rear muffler.  A heavy power load  will 
cook the inside of the trunk, slower speeds mean cooler exhaust
