I appear to have an oil leak in an unusual quarter...where the dipstick goes into the engine. Its a Ford sigma 1.6 (2009) car.
Any experience or thoughts?

g A few drops or a lot? Has the dipstick tube cracked or come lose? Is the engine over filled with oil? I have no idea how the dipstic tube is fixed into the block. There could be an "O" ring failure.

It's a few drops but it's ongoing. It's not residue from the stick being put back on the block. I will try to access it and check the O ring I appear to have an oil leak in an unusual quarter...where the dipstick goes into the engine. Its a Ford sigma 1.6 (2009) car.

on my CVH 1600, the dipstick tube just pushes in to the block, its a tight fit but it goes in as far as the flange and thats it. For oil to leak at this point, would seem to mean a groove in the block or a crack, as there is at least 5" of dipstick in the block. Its not dripping from somewhere above (Rocker Cover?) is it?

Are you sure the engine is not over filled with oil?

The dipstick tube on the 1.6 Sigma will easily pull out of the block. It is supported by an upper bracket which normally prevents this. It is a push fit with an "o" ring in the block. This may have come adrift and will allow some oil to drip.

Increased pressure in the engine block may be causing oil to blow out. May be worth checking the crankcase breather system.
