you will need a 10mm 1/4" drive socket as well as a universal joint and some extensions to get to the bolts tucked behind the blocking plate on the transmission, which is held in place with 2 13mm's I think.It's not that hard to remove. A new oil pan gasket can be purcahsed for relatively little through germanautoparts.com (http://germanautoparts.com/Volkswagen/Golf/Engine/107/5) $15?
I wouldn't drive the car as the plastic could get sucked up against the screen on the oil pump feed line and cause oil starvation
