1998 Honda Civic Noise After Belt Job
Thanks again for all the info!
Suggested Repair
Have the timing belt tension reset to specification rather than left overtight to stretch. Also inspect the timing cover for misalignment or contact with the belt, especially if hard acceleration produces a rubber or plastic smell. If the original shop cannot correct it, have another shop verify tension and cover clearance.
Conversation Summary
A 1998 Honda Civic developed a whirling noise after the timing belt and accessory belts were replaced. The mechanic said the timing belt was tight and needed to stretch over 100 to 150 miles. The expert said timing-belt tension should be measured and set correctly, and that overtightening can cause premature crankshaft and camshaft bearing wear. The expert also noted a mispositioned timing cover can rub the belt, often with a burning rubber or plastic smell. The owner reported a pinging noise, continued whirling, and a rubber-plastic smell under hard acceleration after two return visits, and planned a third inspection or another shop.
