Oil leak

Hi has anyone had an oil leak from the inlet manifold on the back of the cylinder head.

It's a BLS 1.9 tdi am just wondering if the gaskets have broke.

When a look down the back of the engine inbetween the cam cover and the manifold theres a little puddle of black oil.

Ave replaced the cam cover gasket thats perfect no leaks but ave still got this little puddle of oil the only thing a can think of is the manifold gasket has broke any suggestions please.
