Oil leak?

Over the last few days noticed oil on the floor under my mk1 when I pull my car away. I keep checking the engine oil level but it does not seem to be decreasing. Any suggestions as to what it could/ might be? Cheers.

How much oil on the ground? A few drops will take some time to show up in a change of oil level. Have you had a look under the car to see where it's dripping from, engine or gearbox? Most commonly can be a leaky sump or rocker gasket, but could also me one many other numerous oil seals, o-rings, gaskets or sensors.

Cheers
