My car began running roughly and has very little power. on 2001 Chrysler Sebring

The exhaust is white and one spark plug is covered in oil (around threads). I cannot really drive the car due to the lack of power. I replaced the spark plug and there was no change. Any suggestions?

Leave that plug out, after car sits for awhile have a helper crank engine and see what comes out of that cylinder, from a safe position of course. Maybe unhook other coil connector's. Loosing coolant? Using oil?
It's not using coolant and it's just oil. I took the valve cover off and there's a little oil in the depressions in the valve rocker arm base (the unit above the valves). It doesn't look excessive but maybe a little more than expected.
Test compression! If that cyl is low, time for teardown inspection. If the plug tip where it fires is covered with oil, there is a problem inside of that cylinder.
That's where its at. Am I looking at a grand or more for repairs?
Most likely but no way to tell without more testing by a mechanic.
God luck with it!
Thanks brother. I really appreciate the great work you guys do.
Sure thing! Hate this happened at xmas! Maybe it wont be too bad. But hey, it's fixable!

SOUNDS LIKE THE VALVE COVER PLUG SEALS ARE BAD AND OIL IS CAUSING A MISFIRE.SEEK DIAG
Well, the oil is on the thread side of the plug and not the top side of the plug. I checked the valve cover plug seals and they seemed fine (I know that doesn't mean much). I can't get it out to the shop at the moment. I'm looking for some other possible solutions.
Are you saying the exhaust smoke is white?
Yes, the exhaust smoke is white.
White smoke is coolant; Consider finding someone to help you test for intake or head gasket diagnosis.
Thanks, I'll see what I can do.
