I just took off the compressor housing on my stock k03. Surprisingly, it is only held on by 4 bolts with a pretty low torque on them. I didnt expect that
There is some minor damage on the blades. Also, it appears there are some BURRS left from machining or more likely just damage. Can somebody who knows this turbo inside and out confirm this?! I also spotted a casting mistake.
Also, when I spin the wheels, there is a slight grinding noise. Something in the bearing maybe?
Below are 3 images. One has color coded circles to show you points of interest. The second is the same image without the circles. Third is the exhaust turbine. No damage, but discolored.
Here is the color code info:
Blue --> casting mistake
Green --> slight upturn on the tip of the fin
Red --> scraped fin. No damage found on housing.
Yellow --> possible burrs left from machining or just damage. very rough and sharp. this is very hard to photograph
