I do notice that there is always a drop of oil on the drain bolt. So im pretty sure its leaking from somewhere but I have no idea where its coming from. When I change the oil i tighten the bolt really well so I know its not leaking. The oil filter is also tight but could it be leaking from somewhere around the filter area? Since the filter is directly above the exhaust I think its dripping onto my exhaust and thats why its burning.
