I've said it before and I'll say it again the sts oiling system sucks ****. I had to deal with this on a guys 350 and the only thing that truely fixed it was a 5/8 drain into an upgraded scavange pump relocated to the back of the car (because those pumps push not pull) with a .035 restrictor in the feed line because the z routinely goes over 80psi oil pressure, and 1/2 return line from pump to engine. the line sizes are all ID and you can use a 5/8 from pump to engine too but half inch will do.

Also check your air pipes and intercooler chances are they are full of oil too. if so clean your mafs
