Make sure the darn oil cooler is tight the next time you change the filter!
Scared the crap out of me, I was in the middle of a moderately hard launch when smoke started rolling out like it was a Nascar. :x
The car blew out a couple quarts of brand new Mobil One right out of the cooler. I had to limp it a few blocks with marginal oil pressure. Had a little bit of lifter noise when I shut it down, but it was fine when everything was tightened down. Time to look it over again tonight, I guess.
