I have a RX 300 Year 2002 with 60k miles, bought it CPO in 2005. I got a CEL with codes 300, 301, 302, I went to a Lexus dealer and was told to replace spark plugs, I got it done. Just as i left the dealership the CEL came back, this time they suspected Piston Rings and tore the engine apart to find that the rings were perfect. Now after furthur inspection they point to engine block with some rough surface and gaps. They've requested the Lexus for any goodwill help on Fri(1/30) and are waiting for response. Has any one had this kind of problem? What's my best course of action? What's the typical cost to get this repaired?
Thanks - Sumanth
