One problem related to engine rattling and whining sounds has been reported for the 1999 Toyota Corolla. The most recently reported issues are listed below.
My engine makes rattling noise since it reached 30,000 miles. The noise only comes for first 10 minutes when the car is cold. I reported this problem to carousel Toyota, PA during warranty period. Since at that time the noise did not come they could fix it as noise only comes when car is cold. Now my car is out of warranty and engine still makes rattling noise.
