Robert is a good mechanic. He came on time and did a good job in replacing the gaskets. It's been two days I didn't see any oil leak. Though my only concern was after the repair Robert forgot to clean the spilled oil on the parking spot. I am not exactly sure, whether the mechanic is responsible for cleaning the already leaked oil on the engine and on engine splash shield. But I expected it be cleaned. Apart from cleaning the oil, he had done a great job. If the cleaning part is not his job, I will definitely give 4.5 stars for his repair. As I expected it be complete giving him 3 stars.

All about Oxygen Sensor Replacement

With each new model year, manufacturers are adding more oxygen sensors to better manage engine operation. Some high performance engines have an oxygen sensor for each cylinder as well as one for the rear of each catalytic convertor. The sensors are located either underneath the hood or underneath the car. The oxygen sensors are connected (screwed) to the exhaust pipe, either in front or back of the catalytic converter. The front (upstream) sensors measure the amount of oxygen in the exhaust system. The purpose of the front oxygen sensor(s) is to measure how rich or lean the gases are as the gases exit the combustion chamber. Depending upon whether the exhaust gas is lean (high in oxygen content) or rich (low in oxygen content), the amount of fuel entering the engine is adjusted by the engine management computer to try and maintain an ideal mixture that produces the lowest emissions output from the catalytic convertor. Rear (downstream) sensors are located behind the catalytic converter. The purpose of the rear oxygen sensor(s) is to monitor the oxygen content of the exhaust gases leaving the catalytic convertor. If one or more of the oxygen sensors are faulty, your car may not pass the emissions test. If you drive your car with a faulty oxygen sensor, you may get poor gas mileage and it can damage the catalytic converter.
