Both of my MC donor motors for my 4ktq conversion have typical NE rot. (No comments
necessary from you, Bruce Bell, or other Steamboat attendees). And on both, the solid
portion of the turbo coolant feed line are what I would categorize as less than solid. I have
purchased the metal portion of the feed line, at ~$60, but have no plans on replacing the
plastic lined rubber hose or the banjo fitting itself.
On the turbo coolant return line, neither metal or rubber/plastic portions are in bad condition.
I would only replace these pieces if I was worried about the connection to the turbo, or if
the plastic\rubber piece appeared visibly damaged or heavily worn.
HTH with another data point from rusty NE...

It's not! I queried the list about this a while back. The only reply I got for
BTDT's was from Graydon (thank you again for trying to help...) who said he
did it with the engine out of the car. Well, I did manage to remove it by
using a crow-foot socket to remove the fitting at the turbo. Once I removed
the line I also noticed it's hose is very different from the upper hose in
that it is lined with a semi-rigid poly (?) material. I examined said part and
realized it wasn't going to leak anytime soon (if ever) and re-installed it as
is. I imagine that a car in an area prone to rust may have other problems with
this coolant line, like the crimp rusting away. I doubt that the hose portion
will ever fail though. Anyone else have BTDT's on this little coolant line?
For now, I keep a wary eye on mine when under there changing the oil filter,
etc.
