OIL CHANGE ROLLER COASTER

A MISTAKE MADE PERFORMING AN EVERYDAY SERVICE LEADS TO COMPLICATIONS FOR ALL INVOLVED There was a local repair shop that had an oil change go wrong on a 2011 Kia Optima with a 2.4 L engine (Figure 1). The oil filter was installed properly, and the correct oil type and quantity was put in the engine, but the drain plug was never secured with a wrench and only hand tightened. The shop owner was not a happy camper because he discovered that the drain plug was missing and all the oil drained out, leaving behind a seized engine. The engine shop recommended a replacement crankshaft, main bearings, rod bearings and an oil pump.
