New engine whistle/whine
I changed my oil/filter today and then ran the engine to circulate it around before checking the level again, and heard this high pitched whistle/whine when the hood was open. Don't really hear it with the hood closed. First I thought it may be a vacuum leak, then I thought maybe a pulley bearing or similar. It's loudest I think in the left front of the engine. The pitch rises with increased engine speed. The car runs perfectly, no problems at all. Any thoughts or suggestions or can I just ignore this for now and wait for something to happen?
I'm having trouble uploading a mov file because the site won't take it and I don't know how to edit it to a shorter version or convert it to something else so I can't give any more clues as to the whistle sound.
Thanks anyway.
