In mulling this over I have a couple of questions before I take the plunge this weekend:

1. Oil will reduce the octane value of gasoline. This change will presumably put more oil vapor into the intake manifold. Has anyone noticed a tendency to ping/knock with this set-up?
2. I'm wondering if more oil combusted could foul 02 sensors or catalytic converters.

Of course, other cars use simple PVC systems and don't necessarily suffer these side-effects, but I thought I'd ask.
