[Vwdiesel] Turbine blade nicks

[Stephen Kraus]

I did a simple test to find the leak: filled the intake and exhaust ports
with WD-40 and watched for leaks from the valve. All the others held their
liquid....the intake on #2 had a large streak come out.

Yeah, the valve seals, guides, and retainers all cost me about $40 all
together.
