    Not really Odd , Rust film is a deposition from Steel parts subjected 
to Ozone
    reaction corrosion, the  TMF deposition Opti Disk cleans up nicely.
    At least in ones I pulled  apart  weren't  [c]rusted.
    Failure of the venting system , which leaves behind condensate speeds
   the degrading of the Ignition components with respect to the Ozone / 
condensation
   interaction. Isn't Ozone gas corrosive in it's own right ? Look @ all 
the rust in an HEI
   reluctor/ transducer points after long term exposure. SameO , SameO. 
Small cap
   Flying magnet  dissie gets [C] rust from ozone as well. Suppose one 
could  call
  the operating dist a Ion Vapor Deposition Chamber of sorts. Hmmm , mix Ozone
  with Ethelene Glycol [Salts] would indeed be deadly corrosive. Anyway, 
nothing
  lasts forever, there's always Gotchas' .
