What action should a smog check inspector take if they observe crankcase smoke?

When a smog check inspector observes crankcase smoke, the appropriate action is to document and report the issue. Crankcase smoke, often indicative of excessive blow-by gases due to worn engine components or an oil leak, can significantly affect a vehicle’s emissions performance. Noting this issue in the inspection report is crucial, as it highlights a potential problem that could lead to increased pollutants being emitted into the atmosphere.

Additionally, by documenting the crankcase smoke, the inspector provides valuable information that may guide the vehicle owner in addressing necessary repairs. This promotes environmental compliance and ultimately contributes to reducing air pollution. Recognizing and reporting such issues aligns with the inspector’s responsibility to ensure that vehicles meet emissions standards, thereby fostering accountability and transparency in the inspection process.
