hi, i have 1996 1.6L corolla AE102, it's been great car to me for almost 10 years. i experience rattling noise when exhilarating , but it's only when engine get's hot, that's approx after 10min, it sounds like pinging rattling ringing noise, which is the the worse at gear downshift between 70km/h and 80km/h ( it's a 3 gear automatic with approx 280 000km) i have changed the timing belt around 2 months ago that's when that noise escalated to a loud worrying level. old belt was stretched approx 5 degrees ahead ( crankshaft was ahead of camshafts 5 deg. ) when the car is cold , first few minutes or km, there is no noise, car is smooth , quiet and strong, but transmission doesn't change gears for those few minutes, it's still 3000rpm at 80km/h. if this noise is from valves that are rattling around, i guess i should measure the shim distance from the camshaft when the engine is warm (instead what is recommended in the Haynes repair manual - at cold engine) if it's something in the transmission - it's out of my abilities. thanks , martin.
