Check your plug wires - When it is dark, mist(spray bottle/plant mister) the wires, and look for arcs.
If your oil isn't coffee colored, and your coolant doesn't have black spot floating in it, I would lean towards needing new valve seals.
BTW...are those non-resistor plugs? Who made the wires? (see sticky about non-resistor plugs)

Larry,
Would you happen to know the gap off hand for the M117? The plug wires are Bosch and seem to be original. the oil definitely needs changed and is a light brown color. I couldn't get a good look at the coolant as the level is low but I will check tomorrow. The plugs are probably original. They say Bosch Super W9DC Made in Germany. The car only has 79,000 miles on it, but it has sat for the better part of the last 5-6 years.
