Problem
On certain CT13 engines with SCR, carbon can build up on the top lands of the pistons and cause the
piston rings to stick, leading to loss of oil control in the power cylinders and increased oil
consumption.
Solution
An updated cylinder kit is now available to address this condition. The updated liner integrates a
removable "anti-polish" carbon scraping ring which sits in a machined counterbore. This Anti-Polish
Ring (APR) has a smaller internal diameter than the rest of the liner that allows it to scrape carbon off
the top land of the piston during normal operation. This action of continuously removing carbon
buildup from the top land of the piston prevents the rings from carbon packing and losing oil control
in the power cylinders.
Note: APR liners cannot be mismatched with standard liners. Ensure that all six cylinders have APR
liners installed.

Note: The parts listed in the Table 2 are to be replaced under warranty during the warranty period.
This is an update to correct the symptom of excessive oil consumption on CT13 engines with SCR
and is not considered a mileage overhaul.
Note: CT13 engines with SCR have two different cylinder liners available. It is important to verify
that the most up-to-date liners are being installed.
Diagnostic Steps
Refer to the above mentioned appropriate engine diagnostic manual for oil consumption diagnostics.

Repair Steps
Refer to the above mentioned appropriate engine service manual for base engine repairs.
Note: Due to the large amount of oil the engine has consumed, removal and baking of the Diesel
Particulate Filter (DPF) is required to ensure that repair is complete. Refer to the above mentioned
appropriate truck exhaust system manual for DPF removal and baking procedures.
Note: CT13 connecting rod bolt torque is critical. Follow the procedure exactly as written using a
calibrated torque wrench.
