Update. . After working good for a few days it started smoking today. I pulled out the intercooler once again just to find the turbo oil feed and drain lines looking dry, not leaking. The only evidence of a leak I could see is from the flange between the compressor outlet and the elbow that connects the turbo to the intercooler. Also I checked in the compressor and it was clean, no oil. After inspecting the elbow apparently it has 2 small cracks where the rubber seal goes and it seems that the plastic flange is slightly warped, probably due to the heat
So the question is where can I get a new replacement for the elbow and the seal?
