I'll give it a go but don't understand your comment after the "high crank case pressure"? This is insight of what is happening with high C/C pressure.
Did you get a CEL for this? High crankcase pressure is excessive pressure called blow-by, which is result of worn compression rings, compression gasses blowing past the compression rings and into the crankcase. This will be caused by very dirty oil not being changed at recomended interval, also messing up the PCV valve in the process. A tight engine will have very little blow-by, the cranck case is purged by the PCV valve located under the intake manifold on the 4i and to service it you have to remove the IM. Not to hard a job, check posts if necessary. The PCV valve is essentially a check valve, if you can find the hose to it, you should be able to pull air through it from engine but not blow back through it. This is info from service manual and does not give picture of actual location that I could find anyway.

i don't see how anything would shred the boot though as the boot is in the head, not exposed to any of those pressures. the plug would be in between any pressure variance in the crank case.
if the plug was not installed correctly however, each combustion stroke would have that thing wobbling around like crazy and that would be the only thing i'd imagine that could ever impact one of the boots.

Like I said I did not understand your abreviation, and what shreding a COP boot is either and probably should have left this one alone. I know the turbo will certainly try to push compression gasses past the compression rings and into the crankcase creating the pressure you asked about much more so then normally asperiated engine. I know engines very well but have not learned all the abreviations used being old school, just explained high crankcase pressure from my experience.
