I would probably take that story to another mechanic and get a professional opinion.nauy wrote:so they have to replace the engine pipe, and deep cleaning the engine, that will cost $2000. I don't understand why this could happen, my car has no smoke before, and they just did transmission fluid exchange and complete fuel system service.
English is obviously a second language for you. If you went to a mechanic for whom English is his main or only language, it's hard for us to know what he really told you, let alone what he really thinks is wrong. I can imagine that the difficulty is a communication problem and that the mechanic is innocent, though it seems unlikely based on the information you've provided.
