bad luck.. thanks for bumping this thread though good read

I was thinking about trashing the PVC now I'll be doing it for sure... I hate unnecessary crap like that.

It might be interesting to see how the JDM version has theirs setup, IIRC they aren't required to use a PVC system as part of their emissions laws so the Isuzu engineers would have likely gone the rout that makes the most sense for performance and reliability.
