[s-cars] Hole in Cross-over Tube

[Sean Douglas]

Today, under full boost, I heard a loud whoosh/whistle and loss of power
- sounds like one of the boost hoses let go. Funny thing was that the
PSI didn't drop by much, maybe 5 PSI.

Headed straight home and put it on jackstands. Removed upper IC>TB hose
- good. Pulled michelin man - good. Inspected the x-over tube and lo and
behold, I found a small 1 cm dia hole in the x-over tube on the upper
side near the michelin man (my 1997 has the plastic tube rather than S4s
which got a metal one). Turns out the mounting tab had broken off and
the plastic tube was rubbing against the mounting stud wearing through
the tube. As a temporary fix, I wrapped it with duct tape and re-mounted
the x-over tube so its not contacting anything. Also, the m-man hose was
rubbing against a rubber line (hydraulic, I think) and had started to
wear this through too. The hydraulic line was rubbing so much that the
metal braiding is starting to show!. A quick test drive showed that the
duct tape is holding, I guess it will have to do until I can find a
replacement. I priced a new x-over at the dealer and it retails for
$268, ouch! (that's Canadian dollars, BTW).

Anyone have a good (cheap) source for a new x-over tube? Are the metal
ones from the S4s still available? I seem to recall someone selling a
fabricated metal x-over tube, either on this list or ebay a little while
ago. Anyone remember?

Thanks,

Sean
