My car (2000 Taurus Vulcan) has been using quite a bit of oil for a while now, and today i added some dye to the oil in the engine so i could pinpoint where the leak was. I found drips of oil on the bottom of the starter which is just below the oil filter. I put my car up on the hoist at work and started the car, and sure enough i could see what looked like an oil leak at the bottom of the oil filter. The filter is on tight, and its leaked for a while so i think the engine side has a problem keeping a seal. Any ideas on how to fix this? The next oil change i am going to check the oil filter area of the engine and clean it up with some emery cloth. Could it be warped or something?
