This question is primarily directed to John Slade, but all other replies are
certaintly welcome....  On John Slade's website, there are some pictures
which show the various ports/connections for the 13b.  On one picture,
showing the side of the engine where the intake/exhaust ports are,  there is
an arrow pointing to a port on the flywheel end of the engine, which is
labeled "turbo oil return".  There is another caption showing an arrow
pointing to a port on the opposite end housing, under the water pump, which
is also labeled "turbo oil return".  Are there two return lines coming off
from a turbo or is it that either can be used?
      I am considering using one of these for my PSRU oil return instead of
returning the oil back to the oil pan.  Might this work?   Thanks in advance
for your replies and advice.  Paul Conner
