Ford Fiesta Zetec Oil Leak

[fiestaowner9910099]

Hi, my partner has bought a Ford Fiesta Zetec, I noticed spots of oil underneath.

The car is a 53 reg: & looked to have original oil filter! I thought the seal may have gone hard, as the oil seemed to be dripping off the filter.

So I changed the filter & put new oil in up to the top mark on the dip stick & washed the sump off & cleaned all around, etc.

Today when she got back from work I checked underneath & there is a film of new oil on the sump, it didn't look to be off the filter, just a small amount but there all the same . . . Any ideas, sump gasket perhaps or sump just wants tightening?

Not the end of the World I know, but I like things right.

Thanks in advance for any replies, they are much appreciated.

Its quite possibly the same problem I am having with my wifes SportKA and have had a numerous other Fords in the past.

If the leak appears to be coming down the front of the engine and is probably being blown back under it as you drive, and no evidence of leaks around the top end (rocker cover etc), chances are it is just the oil pressure switch that needs replacing.
