Dodge Factory Service Advisories & Field Notes

P0300 / P0301-P0308 'Hemi Tick' and Camshaft Wear

5.7L and 6.4L Hemi engines frequently seize needle bearings in the Multi-Displacement System (MDS) roller lifters, which grinds down the camshaft lobe. If you have a persistent single-cylinder misfire accompanied by a loud metallic ticking, inspect the cam lobe with a borescope.

P0128 Thermostat Failure

Dodge thermostats frequently stick partially open or have broken rubber seal gaskets. Replace with an OEM 203°F thermostat unit.
