Modern Vespa

Hello,

My vespa has just developed an oil leak. Its done about 1000Km since a full engine rebuild 2 years ago.

Oil drips from from where the accelerator, rear foot brake & gear change cable run through the underside of floor pan to the engine of the scoot ( see photo ) There is no oil leak I can see from visible engine areas of the scoot and no oil drops on the floor below the engine.

Its a 1962 Vespa VNB 3T 125 2 stroke. It looks like gear box oil as the oil on the floor doesn't have a fuel smell.

I have put a snake camera in where the carby air inlet hose goes thru the body to check if the fuel tap below the fuel tank is leaking - seems ok.

All visible engine gaskets look unstained.

Any advice is appreciated or where to look.

Thanks

Conrad

Not sure how you would have any fluid, other than fuel coming from that spot. Have you cleaned or lubed your cables lately. Grasping at straws.

Hive?

is it coming out of the bottom of the fuel and oil tank and dripping down?

Slow fuel line/tank/petcock leak. The gasoline evaporates out leaving the oil behind. Once enough collects, it starts leaking out of the bottom. Pull the tank and you will be able to figure it out.

Thanks for replies.
