Geeetech prusa i3 mk 1 dripping extruder

[ValOwnz]

Hi,
My extruder is dripping PLA filament at 170 degrees celcius, even before print start. During the printing, when the extruder moves without aplying filament, the extruder drips extra liquid filament which causes printing quality degradation. I am attaching a photo.

If anyone knows anything about how I can regulate the extrusion I would be grateful for any assistance,
