I will add that I wanted more whine, so I pulled the blower lid-off probably around 500-miles. It already had a residue of oil on all surfaces, and had also little puddles in the blower housing ribs that are above the rotor case. Because of my long-term plans, I decided then I was putting a catchcan on. I understand the warranty, but I'll have my car way beyond when the warranty expires. Having a little more boost just exacerbates what I see as a problem, and the catchcan actually collects a fair amount of oil. I get about a teaspoon-tablespoon every oil change. It's been changed, after the initial 500/1000 intervals about 2-times now. I can barely feel or pick-up any oil with my finger now, rubbing it behind the TB, in the snout. I'd almost need a paper towel to collect anything.

JMHO.
Because mine's a keeper, I also installed a catch can. It catches about 3-4 ounces of nasty watery goo every oil change.
