get new oil filter from motor factors, if "paper" type filter housing on top side of engine you will need 32mm socket for this no need to drain sump , if screw-in metal type you should see it on bottom half of engine, drain sump, push a screwdiver though old filter (oil will drip though holes) and unscrew, put thin layer of clean oil around new oil filter seal and screw on hand tight. re-fil sump with oil to correct level, run car for a couple of minutes, let oil settle and check oil level again.
