RE: Turbo oil & oil cooler lines

[Aleksander Mierzwa <alex@matrix.com.pl>]

Removing the lines from an old oil cooler is usually a major PITA. The
rocket scientists at Ingolstadt put the steel fittings on the aluminium
cooler, which results in electrochemical corrosion. Leaving the fitting
soaked in a good penetrating oil for a couple of days can help a little.
Should you happen to destroy the threads or rip off the fitting, the oil
cooler can still be repaired. Let a machine shop make a new fitting (it
must be made of aluminium) and it can be welded in place of the old one.
Just one precaution: choose a competent weld shop to do that. I had my
oil cooler ruined by the welder who used wrong material to weld it.
