I have a Toyota Corolla 99 that I have owned for a bit over 2 years; it has 97500 miles. After around 2,000 miles after an oil change it starts burning oil (no smoke or smell). I tried to check it often to make sure I am not running on empty. The last time I had to fill it up once and top off a bit another time before the oil change. I recently also changed the serpentine belt.
I thought the serpentine belt was the noise I was hearing when idling. Now, the noise is still there. Does not get worse when accelerating so hoping it is not a engine knock. Was told by Autozone guy that might be the iddle throttle. Hard to describe noise. No clank, almost like something spinning with a noise every 2 seconds.
Possible spark plug issue? Any ideas? Taking it for diagnose next week. Thanks!
