I've seen this in some older cars and it is usualyy oil leaking past the valve seals when the car is sitting, if this is the case it probably isn't a big deal cars with this problem used to go a long time like this. Of course modern cars being what they are it could cause a fault in a sensor. I would think as long as you changed the oil regualarly that there really shouldn't be a major problem with the engine, of course I am not familiar with the symptoms of the reported engine problems either. Hope you have gotten the problem diagnosed correctly. Scott

I'm fairly sure its caused by leaking valve stem seals, however, I'm told that the heads must be removed to replace these seals.
