Description of the problem | I started noticing a knocking in my engine. I reported it to the toyota service department on 9-9-14. I was told by the toyota service department( the one that has done all of my scheduled maintenance) " no abnormal sounds heard at this time." in hind sight maybe they didn't hear the noise because she was low on oil and only listend for the noise after the oil change. I was never told that i should check my oil for leakage in between my scheduled maintenance! I checked my oil one day at random after i heard knocking again and she was very low on oil. I took her to toyota and told them she was consuming oil. They suggested a fuel induction service for which they did on 1-12-17, which didn't fix the problem. On 9-12-17 at her next appointment i reported again the oil usage. Outcome; " performed inspection, found slight oil seepage at engine oil pan. Pcv system is working. Engine must be burning oil. Pistons and rings would need to be replaced." big surprise there. I was so naive but i did take her to different toyota service place for a second opinion. And yes you guessed it another engine oil cleaner service. And suggested piston and rings replaced. It was a mechanic friend that we took her to that kindly did some searching and found that toyota had issued a tsb on august 11, 2011[1](# fn:1) to dealerships which says: " some 2006-2011 model year vehicles equipped with the 2az-fe engine may exhibit engine oil consumption. The piston assembly has been changed to minimize oil consumption." and that po3o# (cylinder # misfire detected) dtc may also be set as a result of oil consuption" obviously there was there is a design error of the pistons. |
