I have been reading up on turbo replacement procedure and I have found this list: First, there are a couple of questions that I have about the list:
a) There is no pre-lube instructions, which opening in the turbo should be pre-lubed with motor oil?
b) Is there any where I can get a good explanation of all of the connections in the GT17 turbo?? I have searched a bit with no luck.
2 air openings, pretty easy to figure out
2 exhaust openings, pretty easy to figure out
3 round openings in the center, all banjo bolts?
1 round / two bolt opening in the center.
1 Hose fitting off of the waste-gate
1 Hose fitting off of the air side of the turbo.
I guess I am looking for the "name" of each of the fittings to help with the info below. Thanks in advance jeffo2 ort11
