Question about 2012 Kia Optima LX Sedan 2.4L 4-cyl. 6-speed Manual
Oil leaks around filter, changed filter twice at dealer and still leaking.
If at filter it could be only what comes out (oil drip) when changing oil filter. If filter is good then use oil filter tighter tool to tighten the filter snugger. Make sure its not the oil bolt that is leaking, which could leave that pesky oil spots. Tighten it or replace oil bolt with new one.

SOURCE: Oil Leak from oil filter
Seems to be a common problem.
there are two "O" rings a small one inside, and a larger one in a shallow groove where the housing mates to the block.
Would be an easy fix, except for the fact that one nut is almost impossible to remove unless the engine mount is removed.
My 2002 Kia Sportage developed the same problem, which I originally thought was because the oil filter was not tight.
it is a poor design, as the original O ring should have been made so it stayed more flexible IMO.

your valve cover gasket may have blown. This can happen if you overfill above the required dipstick level. take off the valve cover and check the gasket. Better to be under the level than over. The oil preassure will try to blow from where ever there is a weak gasket.

It is a Valve Cover Gasket. You can get a new one at any Auto Parts Store. To make this repair last longer, Do not get the Cheap one, Get a Felpro Gasket and it will Quadrupel the Gasket Life. Please Rate My Response! Thanks!

On my wife's car the mechanic said it was gas cap. (NOT!!) I cleared with an OBD reader and the code suggested a leak in the evatorator system. I found a steel tube that was routed over the weld flange of the gas tank. It went from the front of the car, down the drivers side, over the weld joing of the gas tank and into a charcoal evaporator filter on the passengers side near the rear wheel. The tube crossing over the gas tank crumbled when I touched it. I replaced it with a short piece of reinforced neoprene hose (to cross over the gas tank) and a couple of hose clamps. Cost of parts was about $5.00. Havn't seen Check Engine since. Good luck
