400 oil leak
Bellerophon,
> The cross over tubes that I have replaced ( mainly 85A & 85C) are not
> as
you describe . I always thought it was the case but the tubes are just
plain
parrallel sided tubes with the ends counter bore on about 30 deg angle .
The
head has a matching tapered area past the end of the tube . I can only
assume in production that once the tube is pressed in , a taperted cutter
is
used to form the matching counter bore in the tube and head.
I have considered machining a groove in the head near the ends of the
tubes
to fit a small "O" ring to get a positive seal .
"Bellerophon" is that your name ??

Geoff Dowdle
