Road trip blues

[davidkerryedwards]

True enough. In this case the diagnosis was correct and the custom filter
required waiting
for a replacement to be shipped in. Once the new filter was installed, back to
normal. The
filter was not cheap--$82. The plugged up filter was increasing the vacuum so
much at
the turbo intake, it was collapsing a rubber 90 degree hose that is part of the
aftermarket
intake. It was only happening when the rpm's increased suddenly when I
downshifted
from 4th to 3rd on a hill. The slow increase in vacuum on a steady increase in
rpm's as i
shifted up thru the gears was not enough to cause the problem, although the
dirty filter
was reducing the power. I don't think the problem would ever arise on an NA and
I don't
think the factory turbo has any rubber components in the intake system that
might
collapse.

I
suspect there is a fair bit of "custom" work done to the coach that complicates
maintenance issues when they arise.
