Introduction
NOTE
Service Bulletin No. S-SB-0031-14, “2AZ-FE Engine Oil Consumption Inspection Procedure,” MUST
be performed first BEFORE continuing with the procedure in this bulletin.
Some 2007 – 2010 model year tC and 2008 – 2015 model year xB vehicles equipped with the
2AZ-FE engine may exhibit engine oil consumption. The piston assembly has been changed to
minimize oil consumption. Use the following Repair Procedure to address this condition.

(6) Push the piston, connecting rod assembly, and upper bearing through the top of the
cylinder block.
HINT
• Keep the bearing, connecting rod, and cap together.
• Arrange the piston and connecting rod assemblies in the correct order.
(7) Repeat for the other 3 piston/connecting rod assemblies.
F. Remove the connecting rod bearings.
HINT
Arrange the removed parts in the correct order.
G. Inspect the cylinder bore for abnormal damage.
Visually check the cylinder bore for the presence of crosshatch.
• If the cylinder bore has visible crosshatch, the cylinder block is OK to re-use.
• Confirm that only light vertical marks are present, if any.
NOTE
• It is normal for an in-service block to have light markings present from carbon and
should NOT be interpreted as excessive cylinder wall scratches.
• ONLY replace the short block if multiple, severe scratches are present.
• Do NOT hone the cylinder walls.
H. Using a screwdriver, pry out the 2 piston pin
hole snap rings.

measure to determine if parts are suitable for re-use.
NOTE
Due to carbon build up, piston face may need to be cleaned before reading designated piston
type. If piston type cannot be found, reference connecting rod.

specified, replace the piston pin.
NOTE
Connecting Rod type is a matched set with the piston and piston pin. For example: if
