1. New Turbocharger Plumbing Oil Drain Connection for QSB6.7 T3
Option TP97294 will be replaced by TP97898
Robert Fipp

2. Project Scope
Change Summary: New turbocharger oil drain connection, with one higher Y point at a bend location and internal corrugation, will replace current part with external corrugations only in option TP97294.
New turbocharger oil drain connection assembly will replace current assembly only in option TP97294.
The options that are effected and will be obsoleted / superseded are: New turbo plumbing option TP97898 will replace current option TP97294, which will be obsoleted.
Background: The current turbocharger oil drain line is rubbing against the oil supply line in option TP The drain line needs the bend location point changed so it will no longer hit the oil supply line. The corrugation type is also changing.
Implementation Strategy and Date: April 2016

3. Change Summary
External (Annular) corrugations
Current turbo oil drain tube with annular external corrugations.
Shortened 32.4 mm
Internal (helical) corrugations
New turbo oil drain tube with helical internal corrugations. Shortened to prevent interference with turbo oil supply hose.
The top picture shows the current turbo oil drain tube , which is in option TP The bottom picture shows new turbo oil drain tube tube, which is in TP Option TP97898 will replace TP97294.
