Coolant dripping off front of oil sump

[leicesterboy15]

The other day I took the sump cover off my 540 to have a go at the suspension arms and noticed what looked like coolant dripping slowly off the front of the Oil sump. I do have a slow coolant leak, I end up having to top it off once every two weeks or so but I can't see anything in the engine bay. I've had a new water pump and rad in the last year or so. Any ideas where the leak could be to end up on the front of the sump? I've tried chasing up but theres nothing concrete, I'll need to take another look. The rad looks too far forward to cause it to land on the sump. Could it be the head / sump gasket? The sump gasket is showing signs of leaking oil but there is no signs of any water in the oil or vice versa and the car doesn't use any oil. Is the sump gasket a diy job? Any ideas are much appreciated - especially with the weather hotting up!

it's either the hoses or the coolant pump gasket.. probably just a loose or worn hose
