2003 6.0L Power Stroke – RUNNING CHANGES – Turbocharger Oil Supply Line

• Part way through the 2003 model year, the turbo oil supply line changed in design.
• The early design was a quick-connect/disconnect style (left). The improved design (right) provides a larger o-ring       seal and is held in place with a bolted down collar.
• The new design improves the line’s long term reliability and reduces risk of oil leaks between the oil cooler                     assembly and the supply line.
