Engine Oil Leak on 2010-2013 GM 2.4L Ecotech Engines

The AERA Technical Committee offers the following information on an engine oil leak on 2010-2013 GM 2.4L Ecotech engines. This bulletin concerns vehicles that are operated in the coldest temperature regions, where temperatures are commonly below freezing.
The vehicles concerned are equipped with the common GM Ecotec engines LAF, LEA or LUK. Many reports of oil leakage and oil consumption have been reported. The cause of this leakage may be the result of ice forming from collected moisture in the positive crankcase ventilation system (PCV). This blockage allows crankcase pressure to build, eventually forcing oil past the rear main crankshaft seal. In some instances, the seal has become completely dislodged.

No-Start Condition on 2017-2022 Mitsubishi 1.5L Engines

The AERA Technical Committee offers the following information on a no-start condition on 2017-2022 Mitsubishi 1.5L engines. A service caution may help prevent a possible no-start condition after repairs have been made.
When performing engine repair or maintenance, there is a chance that engine coolant or water may leak into the crank angle sensor, causing the engine to stall. This may be due to coolant or water ingress into the crank angle sensor harness connector, resulting in an internal short circuit.

Shop Management Solutions

By Rob Munro

Sometimes running your own shop can feel like you are trying to do 50 things all at the same time. With everything pulling on you from all different directions, staying organized is difficult and making money can be a challenge. We are all creatures of our own bad habits, myself included, there will come a time when we can’t remember all that important customer information in our heads, and the sticky note we wrote it on will have blown into the abyss, thank gawd for the computer and a management software system! Being able to store and manage tens of thousands of customers within a database that can easily be viewed, sorted, and filtered makes everyday administration an altogether simpler experience.
