Don't know about the oil vapors killing them..I've opened one up and found
that the board and pressure sensor were coated in a thin rubber sealant.
(Funky looking board at that.)
Oh man...I feel your pain on the MP Computer and the pinging problem. Not
quite the same but had the Blower on for a few weeks and then
"boom"...leaky belly pan gasket. Had to disconnect the tube and drive it
home without boost. (That's no fun....once you've had it, you don't want to
go back.) ;)

This theory is based on my having a leaking stock intake and very bad
pinging.
Replaced MAP sensor (oil vapors kills them?) - pinging wasn't quite so bad.
Replaced stock manifold w/MPI and it got lots better but didn't go away
completely. This was very confusing as the MPI has a solid bottom. One
day I
decided to pull the PCV off, plug the line going to the TB and put a vent on
the
valve cover where it was - Bingo! Turns out that my leaving out the baffles
on
my MP valve covers was pulling enough oil vapors through the PCV valve
connection to the TB to cause pinging still. Once the baffles were in, the
pinging went away completely. Then the MP computer went back on - a few
tweaks
later and I'm pulling right up to 6k. Does anyone know how hard it was to
keep
looking at that MP computer sitting in my garage for over a year (because I
couldn't use it due to the pinging)???

ps - Don't leave the pcv off - you will be surprised how quick all kinds of
crap
(sludge, rust, black flacky stuff, etc...) gets glued to the top of your
motor
(on the inside!)....
