[QUOTE="TexasJ, post: 1555479, member: 30660"] So I replaced it with a KC Turbo brand pedestal from Jelibuilt Performance. Upon pulling the ffd pedestal I inspected the brown O rings between the engine and pedestal very closely. There was no disfigurement or damage, and no indication as to why they were leaking. I received a set of black O rings with the KC pedestal, so when I installed it I used those. When I put the black O rings in the relief cuts in the engine, I cleaned up the surface really good with a rag soaked in brake cleaner, then I put the O rings in. Upon doing so I noticed the small O ring fit nice and snug into the relief cut, whereas the small brown one I had in previously had a gap between the outside of the O ring and inside of the relief cut. It was small, but noticeable. The large brown O ring from before also had a slight gap, so I didn't think anything of it. As for the large black O ring, it did have a slight gap, but less of one than than the brown that was used previously. After installing with the black O rings and being VERY careful not to over or under torque the bolts, I tested in high idle, and eventually drove around the block. I had a little seepage at the engine and pedestal O rings still, but NOTHING compared to how it was gushing previously. I went back and forth between cleaning it and driving it yesterday and the seeping slowed down some. I think most of it was stuff that spilled when I turned the turbo back over during install and slowly worked its way out. It is still seeping ever so slightly (and I mean very slightly, it hasn't even dripped down into the valley yet) so I torqued the rear passenger side bolt down about another quarter turn (that's as far as I could get it with a pipe over the end of a 10mm box end wrench) this morning and will continue to monitor it. But as it stands right now, as long as it doesn't worsen, it is driveable! I still have no clue why it was gushing oil with the previous pedestal, I can only assume that the oil holes in the pedestal were slightly off center with the ones in the block, and between that and the brown O rings not having a good flush fit it created just enough of a gap to let oil through. That's my working theory at least! Anyway, thanks for the input guys, let me know what y'all think! [/QUOTE]
