Hey Everyone,

So I have been searching and reading everything I can on this subject but can't find anything specific to my symptoms. I just replaced my radiator, water pump, thermostat & housing, fan clutch, hoses and added a Hayden Transmission cooler (bypassed stock transmission cooler completely). I thought I had transmission oil in my coolant because it looked redish, this is why I replaced all of these parts. I did a complete flush with distilled water multiple times until it ran clear. Now, a couple hundred miles later my coolant is no longer green but almost black. I looked inside the oil filler cap and can't see any cracks or coolant or milky foam. It is not a Tuppy head but I'm not sure if the head is cracked. Are there any other possible causes for this "oil in coolant problem"? This is my daily driver I have no other options besides spending $100 a day on uber. I am willing to do the head replacement but I need to drive this thing about 40 miles a day until i can get all the parts/money together.

When you say that you flushed the cooling system, did you just dump and replace with water until clear? Or did you run an actual bottle of flush through the system first? If you didnt actually flush it, the dirty water would make sense.

I would go rent the little tester that you stick in the radiator. It will tell you if you have a cracked head or blown head gasket.

You can test the coolant system for exhaust gasses, http://www.blocktester.com/
The engine block coolant passages often have crud built up in them. A distilled water flush will not effectively clear them.
Also, in a Pennsylvania climate eliminating the stock heat exchanger for transmission can prevent transmission from getting to optimum operating temperature.
