About two weeks ago, I started getting a misfire in cylinder 4. I pulled the plugs and found that all 4 had oil on the electrodes. Think head gasket, I did a compression check and had good compression (170-180) across all 4. I changed the plugs and got the typical oil burn on startup but then it continued. Now, every time I start the car, I get a cloud. To top it off, I now have another misfire (cylinder 3.) Being that I have good compression, my oil is not milky, I have no coolant bubbling, and oil on the electrodes of all 4 plugs, I’m thinking something upstream of the cylinders. Could it be that my turbo is bad. To preface this, I had a CEL for boost pressure so to me, turbo makes sense. Anybody else have this issue? What was your fix?

Spark plug tube seals are leaking oil. It's next to impossible for oil to be in your cylinders with good compression. When you pull a plug, that's when oil flows to the electrode and down the spark plug threads because it has pooled inside the tube. If you get enough oil in the tube, that will cause a misfire. You need to replace the valve cover gasket and tube seals.

What code are you getting for boost pressure?

I caution you about a good compression reading if you think you have oil in the cylinders. The oil can mask a low compression reading by sealing the rings.
Do you have oil in your intake near the throttle plates? You could have a bad PCV valve (those are cheap on the 2.4L). I have also had coil packs go bad and have replaced all 4 for good measure.

More than likely it's the valve cover gasket. I had the same issues and had the gasket replaced today and no more oil.. the part is about $25 and labor is about $140. I would strongly suggest taking it to a shop so you don't crack your valve cover torquing the bolts down.
