What was found

SAID HOSE IS MADE FROM TEFLON. IF INSTALLED INCORRECT OR CARELESSLY, CAN TEND TO TWIST. AFTER A RECENT TURBOCHARGER INSTALL, ALL THREE OF NOTED HOSES WERE TWISTED. THIS CAN RESULT IN RESTRICTED OR BLOCKED OIL FLOW. WHEN INSTALLING THESE HOSES USE THREE WRENCHES; ONE ON HOSE BODY FITTING, ONE TO TIGHTEN HOSE B-NUT, AND ONE TO SUPPORT TURBO DRAIN TANK FITTING.
