Re: XPAG dip tube

[Leclerc, Lawrence A.]

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
