HappyLS430owner Posted November 22, 2012 Share Posted November 22, 2012 Several weeks ago, a serpentine belt was installed. An effective cure for squeeking. My car has 160,000 miles on it and going strong. No real issues. Today, there was a pinging noise and then the car conked out. OMG. The tow truck brought it to my home for Turkey Day holiday and the operator thought it might be a timing belt problem, tensioners, stuff like that. Does this sound familiar?

steve2006 Posted November 22, 2012 Share Posted November 22, 2012 Sorry to tell you but if the timing belt has failed the engine will have suffered major and expensive damage from valves hitting pistons so I hope it hasn't. A mechanic will know as soon as the top cambelt cover is removed. Please come back with the cause when you know. Nearly forgot welcome to the LOC and a Happy Thanksgiving Day.

HappyLS430owner Posted December 3, 2012 Author Share Posted December 3, 2012 The diagnosis is the timing belt broke and the collateral damage is devastating. Looking at having to purchase a rebuilt or new engine. Or, scrap the Lexus and get a new car. Lesson learned: when the engine light goes on, stop driving the car!

steve2006 Posted December 3, 2012 Share Posted December 3, 2012 That's not good then, BTW if the cambelt snaps the damage is done before the Engine Management Light even flickers it's all over in a fraction of a second. Best way is to source a known good and warranted low mileage engine straight from Japan and replace the cam belt before you fit it. Quote Link to comment Share on other sites More sharing options...
