John, blue or black smoke? My friend at BW said it was black (fuel) not blue (oil). It's now blue.
I didn't have any catch cans at BW, I installed them for Thunderhill -- this should have helped reduce the amount of oil going back into the intake.
As far as how long it has been pushing out black smoke, I have no idea -- FF install was about mile 1200, it has 8000+ miles now and out of those 6800 miles, only 50 miles were on track.
Anyway, hopefully this will get sorted soon and I can get back on track
