My engine seized and needs complete replacement due to this oil sludge problem. As a result of the gelled oil, one of the pistons broke off creating a hole in the engine and the motor mount became displaced from the engine, causing the engine block to crack while I was driving the car. I bought the car used from greer Toyota in millbrook, NY in August of 2001 and was told that one of their mechanics would complete a thorough inspection before the car was turned over to me. I have since had the oil changed every 3,000 miles by a trusted mechanic. During that time, I had to replace the oxygen sensor at my own cost, but did not have any other problems until this month. Now in addition to the engine, it appears that my struts are failing as well. I am in the process of submitting a claim for the engine.
