ACURA: Oil Consumption On Manual Transmission Vehicles

In this updated TSB from 2013, Acura discusses how some 2011-'13 TSX models with manual transmissions can develop an oil consumption problem. The TSB states: "If you do not see any other factors contributing to oil consumption, consider engine braking as the possible cause."

According to the TSB, engine braking creates a high vacuum condition in the engine that causes more oil to pass by the piston than expected. Higher RPM downshifts with no throttle input can further increase oil consumption. The corrective action cited in the TSB is to replace the piston and piston rings.

Alternator Testing For No Charge Conditions

Many alternator problems turn out to be nothing more than a bad connection at the alternator or a bad wiring harness.

If only battery voltage is present at the battery on a running engine, does this mean the alternator is “bad?” No, it does not. It only means that the alternator is not charging, but does not reveal why. Therefore, it does not point to a faulty alternator. All too often, the alternator is condemned by technicians due to this test alone. The cause could instead be a module that distributes the power to the vehicle and regulates the alternator.
