Conditions of Audi timing pressure relief

Conditions for Audi timing pressure relief:

If Audi's timing pressure relief fails, it is generally a precursor, and the engine will produce abnormal noise. So it is good to listen to the sound of the engine often. And when running at high speed, the timing will shift. Will lead to engine scrapping timing chain failure will cause engine abnormal sound, high oil consumption, increased oil consumption, car can not start, lack of power, serious exhaust emissions. 1. Check the chain elongation at three or more positions with a spring scale. If it exceeds its service life, it should be replaced in time. 2. Use vernier caliper to detect the wear degree of automobile camshaft and crankshaft sprocket, and replace it in time if it exceeds the service limit. 3. Monitor the thickness of zipper and chain shock absorber with vernier caliper, and replace it in time if it exceeds the service limit. 4. Check the elongation, wear and fracture of the timing chain.
