What does "smoke an L" mean?

H.E.L.P When Staring my car a small puff of white smoke exits my exhaust, smells like a mix or petrol and oil, what does this mean ! H.E.L.P

• Answer:

  Small head gasket leak sounds like. Water or Antifreeze is leaking in and burning off when you first start the car. From your description it's a bit fuzzy how much white smoke is coming out. It could also just be water laying in your exhaust system that burns off? Take it to a mechanic. rules of thumb: white smoke = burning water or antifreeze black smoke = running too fuel rich blue smoke = burning oil
