The problem
THE SYNFLEX-TYPE OIL PRESSURE SIGNAL LINE MAY HAVE BEEN ROUTED TOO CLOSE TO THE EXHAUST MANIFOLD. EXCESSIVE HEAT MAY CAUSE THE LINE TO RUPTURE, AND OIL LEAKAGE MAY OCCUR.
What owners should do
THE DEALER WILL REROUTE THE OIL PRESSURE SIGNAL LINE TO ELIMINATE POTENTIAL FIRE HAZARD, WITHOUT CHARGE TO OWNER.
