Wilsons Sandbox

While dismantling my XPag the other day, I came across the mysterious tube
projecting downward out of the rear main bearing cap approximately 5". It
was loose in its mounting and came out with a slight pull. Apparently it was
pressed in Can someone tell me:
What is its purpose?

Is it really necessary?

If renewed, should I consider brazing it in to supplement the current press
fit?

Hi Larry,
I believe you are describing the tube which directs the oil to return from
the rear main oil slinger (not seal) to the sump. You might simplify its
reattachment by using C7 epoxy after cleaning surfaces. Then make sure the
pipe is well open at both ends. In this vicinity it is much more important
to position the end-cap (a fragile casting) attached to the outside of the
block above the crank, best done by removing positioning dowels. Make
certain it is concentric with and very close to the crank. Another source
for oil leaks (among many) is porosity in the aluminum sump. I defeat this
by painting the inside with Rustoleum damp proof primer.
Cheers, Peter
