What makes the noise is the design of the engine uses little (unfortunately) plastic tubes to move oil from the bottom of the engine to the top. They are designed to pop off should an overpressure occur. When this happens there is no oil getting to the cam/lifter and it becomes metal to metal. The good news is that these engines are very tough and you have to run it for a very long time to do any damage. I know. I've replaced mine five times. It costs anywhere from about $400 to $1000, depending on who you have do it.........or you can search the forum and find several very good descriptions, including pix, on how to do it yourself....cost: about $200-$250. I now run lower viscosity oil and haven't had it happen in nearly a year.oleg45 said:I dont think its the belt or the pulleys, going to the mechanic tomorrow.
If its the oil lines, whats actually making the noise?
