Worn or damaged valve guides or valve stem seals.
Problems in this area can allow oil to enter the combustion chamber. Oil will form heavy black wet oily deposits on the spark plugs. Check the exhaust on start up after the car has been sitting overnight. The accumulated oil will burn and you will get some oil smoke from the exhaust on start up and then it will disappear as the excess oil has burned up.
Worn or damaged piston rings, or worn or damaged engine cylinders.
Badly worn piston rings, broken or cracked piston rings, grooves or scoring in the cylinder walls can allow oil to get into the combustion chamber and foul the spark plugs.
Hi Josh:
I'd put fresh plugs in it and drive it for a week, then check the plugs.
Sometimes you will get high compression readings that are not valid because the rings are soaked in oil so they think they are sealed when they are not.
With the engine off, you could try removing the oil filler cap when the engine is hot, then restart it. A little vapour is OK, a lot indicates bad valve guides, head gasket,or ring blowby.
Also, try checking inside the exhaust tailpipe. If it is oily sooty it is also an indication of possible ring problems.
Review the maintenance history. How many miles on the engine? Could be the engine is getting tired.

one thing to keep in mind that even though the vehicle is new you can still have major engine issues, because of the bearing material may have been bad at production.taking this in account any part on a vehicle can fail prematurely either because of poor insatllation or improper manufacturing. As far as oil filters are concerned bthe odds of mechanic installing the wrong filter are slim to none.the oil pressure sending unit only senses that here is oil flowing through it. it doesn't set the light off unless there is absolutely no pressure at all the only way to see the pressure is to have a gauge. oil prssure should be abot 45 psi at 2000 rpms. the only way a filter would effect oil pressure is if it was completely clogged. It would take a great deal of coolant in the oil to ruin a set of bearings and before that happens your vehicle would not run very well and you would notice a great amount of white smoke out the exaust. this would indicated either a blown head gasket.cracked head or a cracked block. you never mentioned what they found in the anaylasis of the oil. I presume that your vehicle is still under warrenty on the powertrain. I would suggest that you have the dealership check your oil pump out. every vehicle will have a small amount of metalic residue in the oil. large shavings and chunks of metal would be a worry. please rate this thanks.

Get a can of Gunk and clean the engine according to the directions there (please do read them), with attention to the area around where the oil leak is. Once you get the motor squeaky clean, you will be able to trace back to where the oil is coming from. It may be running down the underside of a hose so you will need to look carefully. You can do all this in the driveway. You will probably have to let the engine get to operating temp before it will start leaking.

It is a common problem for the seals in the oil cooler to leak and allow water into the oil. I'd check this first, there should be a procedure online somewhere. Try googling "clarks garage"
SOURCE: water and white smoke comming out exhaust
your cooling system is preasureising due to a leaking cylinder head gasket the white smoke you see is coolant passing through the exhaust valve on the offending cylinder have the cooling system tested for CO content hope this advice helps
