Every time the engine is started there is a metallic clunking sound. Once the engine starts and I release the ignition key the metallic sound stops and the engine runs fine. I thought the sound could be coming from the starter motor but standing facing the engine from the front, the noise seems to be coming from the left. I believe the starter motor is at the right.
The car runs very well with no other problem apart from the metallic clunking sound when starting.
Any ideas what the problem might be?
Thanks
