ltk Posted March 25, 2008 Share Posted March 25, 2008 I have a 2002 Impreza. I hear a ticking noise when I start the car but after it warms up the noise lessens. I took it to the Subaru mechanic. They checked it out while I was there and said it is a common problem--it's one of the pistons (I forgot which one). He said other than the noise it's not a problem. I do take it in for regular maintenance. Is this something I need to worry about? Link to comment Share on other sites More sharing options...

porcupine73 Posted March 26, 2008 Share Posted March 26, 2008 Hi ltk and welcome! Here's a good soob article about the noise: http://endwrench.com/images/pdfs/EngineNoiseSum04.pdf excerpt: "Subaru models from the 2000 model year and later, equipped with 2.2 and 2.5 liter engines" ,"A light engine knock, after cold start, that gradually dissipates as the engine warms up and is virtually undetectable (from inside the vehicle) once the engine has reached operating temperature, is a normal characteristic of these engines."
