Passenger leaks on the C4 are *usually* a problem with the dipstick seal, and while messy, it's thankfully a pretty easy fix.
When you say 'dripping on the block' if it's up by the intake, under the upper radiator hose, your thermostat housing gasket may be to blame, or possibly the upper hose itself. If your radiator hoses feel 'crunchy', rock hard, or soft and squishy when you squeeze them, it is time for new ones!
I smile a lot. It makes people wonder what I'm up to...
