My 96 Vahuxall diesel van has just spilt a load of steering fluid (obviously needs to be topped up to stop the awfull sound it now makes when steering!) coupled with this, the engine is now making a whirring sound as it's turning over that wasn't there previously. Any clues to there being anything more serious that I might need to be aware of before setting out in it in the morning? Your help is much appreciated- Rich Glos
