Okay, so since the 300D is the daily driver for the week, I got coolant out of the SDL.
Dumped radiator. Vague dull green, should have used a clean bucket so I'm not sure how much of the dirt was from the car - but ah! Everything else on this car was 100% by the book, was not expecting to see the green. Anyway that was clean enough, just dirt if anything. Then I pulled the drain from the block, using oil catch pan. Dumped into bucket, shocking amount of sludge. And oil! I am ashamed to admit that it took me more than 10 minutes to realize the oil was probably from my drain pan. :) Anyway, I don't have a resolution - will have to stop at the CarQuest to pick up some Zerex tomorrow - but I figured you all would get a kick out of it. And I am glad I drained all that green goop out, will let you know if it helps.
