Subject:
HIGH OIL CONSUMPTION DUE TO WRONG AIR INTAKE HOSE SERVICE PARTS
APPLICABLE MODEL(S)/VINS
2004-2008 RX-8
DESCRIPTION
Some vehicles may experience high oil consumption if the air intake hose was replaced with service parts. The cause of this is the number of ventilation
holes on the hose was changed from three (3) to two (2) for 2009. However, it appears that the service part hose for 2009 was shipped for 2004-2008
RX-8 by mistake since January 8, 2008. If the hose for a 2009 model is installed on a 2004-2008 RX-8, the barometric pressure, which is normally
applied on a small hose (A) connected to the metering oil nozzle is plugged. Engine vacuum then goes to the metering oil nozzle instead so that oil is
supplied inside the engine is more than the Metering Oil Pump (MOP) injects, resulting in high oil consumption.
Customers having this concern should have their vehicle repaired using the following repair procedure.
REPAIR PROCEDURE
Verify if the vehicle has had the air intake hose replaced after January 8, 2008, then replace the hose with the correct one.
