The factory flanges are cast. So, welding to them will prove to be very difficult not to mention they are 3/4" thick as well. Welding .090 wall tubing to it isn't likely going to happen very easily and be anywhere close to strong.
I'm all for welding to cast, but welding .090 wall to cast is another thing all together.

With the design of the 94-97 where you have to pull and install the turbo with the pedestal attached, it is VERY easy to have one of the o-rings get pushed off to the side of the galley port. When the o-ring gets pinched between the block and milled surface of the pedestal, it will not allow full compression on the o-ring. This can hold for a short time but eventually the oil will work its way past the o-ring and it will leak.
I guess that is why Garrett changed the design in 99.
I think if I still owned one of the OBS trucks, I would always have an extra set of pedestal o-rings sitting around since it's such a PIA!

This sounds like my truck. Just pulled the turbo to install e-fuel and it was leak free for almost a week. I hate to have to pull that turbo again! Is there a possibility that the pedestal bolts backed out? They were loose when I pulled the turbo, leak free for two years since I swapped the D66 in. Is there a torque spec for thos bolts? Thanks for any help and advice!
