Let us know, I'd be curious.
I know what Piper (and you) were sayin' about "starting over," draining, inserting plug with new crush washer and oil, but I suspect what he did will take care of the problem. (It did for me last time I changed the oil, though I wasn't using a torque wrench either time.)
The environmental (and frugal) part of me quietly objected to wasting 9 qts of expensive oil if it was not necessary—that notwithstanding the fact that I realize driving a Boxster isn't the most environmentally friendly thing I could do. (I have an 'out'...my wife drives a Prius and, unlike me,
loves it. So we more or less offset each other
)
