Got into my car earlier after leaving it for 8 hours, didnt start. I hate to pump the accelator a little and put the clutch in to get it starting, then when i was pulling off it was spitting a really light blue/white smoke from the exhaust covering the car behind me (I had a little giggle at this moment). Can anyone think what this might be and why? It calmed down after about 5/10 mins. I do have a K&N Cone Filter installed and wondering if its that.
