Question about Cars & Trucks
Haha, you can't be serious! The Vespa has a two stroke engine, and with out oil mixed with the gasoline, the engine will seize solid. You may have too much oil going in which is not being burnt in combustion, and is condensing on the inside of the exhaust, enough to drip out. That is far better though than not having enough oil. Have it professionally serviced and the oil correctly calibrated.
If you mean it is dripping onto the outside of the exhaust, that is a different kettle of squirrels. Find where the drip is coming from and tighten up the union. The tank is quite small and you will see a pipe going to the pump and then to the carb intake manifold.

SOURCE: 1992 ford tempo oil leak?
Definently sounds like the rear main seal. My 97' Dodge Ram has the same issue and it leaks in the exact spot and has the same symptoms. Changing the gasket on the rear seal in simple but it's hard to get it apart to get to it unless you have the right tools and mechanic know-how. Your car seems to be leaking more than mine so it seems to be worst, but it is most definently the rear main seal. I put gasket maker/sealer on mine and it temperarely stopped the leak but due to pressure it will always seem to start again. Your best bet is saving the money or if you have it, invest it and go ahead and have the problem fixed. Hope I was of some help.

Check the oil fill cap and the radiator cap, see if you have a milky scum accumulation on either one, can indicate a blown head gasket or a cracked cylinder where the oil is burning and allowing water intothe hot cylinder which causes white smoke to be emmitted from tailpipe.

The most common cause of blue exhaust smoke is oil leaking past engine seals and into the cylinders where it then mixes and burns with the fuel. This is most frequently seen in older or high mileage cars with worn seals and gaskets. It only requires a very small amount of oil leaking into the cylinders to cause excessive blue exhaust smoke.
Blue exhaust smoke only at start-up can indicate worn piston seals or damaged or worn valve guides which may also cause a rattling noise. An external engine oil leak can drip onto hot engine and exhaust parts causing what appears to be blue exhaust smoke. Other possible causes of blue exhaust smoke include: piston wear, worn valve seals, a dirty or non-functioning PCV valve, worn piston rings, an intake manifold gasket leak, worn engine oil seals and possibly even head gasket failure.
Oil leaking into the cylinders can cause a rough idle, misfire and fouled spark plugs. In addition, a reduction in power and oil loss can be indicators that the blue exhaust smoke is caused by an internal engine oil leak. Internal engine oil leaks can also allow fuel to mix with the oil in the crankcase which will degrade the oil and prevent it from adequately protecting the engine.
Operating a car with a severely dirty oil filter, air filter or improperly functioning PCV valve can also sometimes result in engine oil blow-by, oil loss and blue exhaust smoke. Periodically checking the engine oil level with the oil dip stick will indicate if there is excessive oil consumption. Higher viscosity engine oil can sometimes temporarily reduce the amount of blow-by; however, this is not generally recommended. Excessive blue exhaust smoke indicates a possible internal engine oil leak that should be inspected by an ASE certified mechanic.
