    Smokeín 345

    I know this problem has surely been covered in the past, but I couldnít seem to find a solution to the problem. My 345 drips gas on the muffler causing it to smoke pretty heavily for a few minutes after start up. It seems to be dripping from this part. Does this whole thing need to be replaced or is it just the gasket? I also donít see how Iím going to loosen the bolt off from the other side. Itís an extremely tight fit. Thanks.

    Fuel pump. If that's the left side front, the fuel pump is right above it. It's been the source of many 345 melt downs. Look closely at your first pic center. There is a clear wash area above the gasket line all the way to the top of the pic. The gas is most likely coming from a weep hole in the back of the pump. I would caution you against running it that way but you probably already know that. Also check your fuel lines going to and from the pump. They deteriorate with ethanol and age and are prone to leaking. If one is bad replace all of them.

    Valve cover gaskets are cheap and easy to replace but he said gasoline. Two very different animals and consequences. Gasoline will be very noticable due to odor.

    If it doesn't smell like gas, it ain't gas. Valve cover gaskets. Aluminum covers have aluminum type gaskets. Plastic ones have a thin rubber compound.

    Looks like you need both. Valve cover gaskets and fuel pump. Oil is causing the black and gas is cleaning it off. The new pump will have a drain tube attached to the weep hole. When this type leaks fuel the hose will keep it off the hot exhaust.

    I think the 2000 had the upgraded fuel pump,but this was also the transition year. The newer style fuel pump will have the drain hoses on it.Valve cover gaskets were a common problem for leaking too.

    I do believe I have the newer pump. Iíll dig in there again and try to find out exactly where the leak is coming from.
