Ok so i have a 03 saab 9-3 and i like going for spirited drives in the mountains at least once every two weeks. Last time i went i drove it hard for like 20 minutes then i started hearing a knocking sound coming from the engine so i stopped to check, turned off the engine, and waited 2 minutes then i turned on the car again and the sound was mostly gone. I drove it really easy for about 2 miles and the knocking sound was completely gone.
This has happened twice but it never makes the knocking sound any other time, only after driving hard for more than 15 minutes or so.
I've driven about 150 miles since then and all seems normal.
Anybody have any idea? Should i be worried?
Thx in advance
