At first i thought it was just that the aurora 3000 had blown it seals, because there was oil on the intake side of the turbo. I put the S366 on Saturday and it was ran with a light haze at idle, but as I revved it up it started to blow white smoke and leak oil. One of the probes in the up pipe doesn't stay in properly and it was shooting oil out before the turbo. Don't the lb7 have oil cooled pistons, the bottom of the pistons?
