Oil Leak

[mondeo161]

Hi all.

When doing and oil change on my sons 2010 Focus 1.6 TDCi has developed a leak around the lower front right of the engine. Lookd to be above the and all around the sump.

I will give it a clean tomorrow but am wondering if anyone has had to replace a sump gasket or crankshaft seal for a similar problem. The car had done over 170,000 but still runs very well.

Thanks
