HELP...8.1 Loosing Coolant!!!
 
So my 8.1L has lost like a quart or more of coolant in the past...oh, 500 miles. WTF, this has just started. I can't find any leaking, don't see any around the heads, where is it going?? Burning it?? Going in Oil?? I am sick now because I was just getting ready to install my turbo setup.

any smoke out the tailpipe? What are your engine temps like.

Is the area below the radiator wet or damp? Might have a small crack in the rad from rock or something and its dripping down when on.

If you change the oil and it looks watery then you know its leaking into the oil somewhere.

Yea, hopefully I can change the oil this week. I sorta frightened as to what I'll see/

Anyone else got any ideas. Anything worse/better? Give it to me straight. What if it is in the oil...leaking head gasket??

If it's in the oil...blown head gasket, cracked head, etc. But before we fear the worst, get a pressure tester on it and see if anything is leaking externally. Could be as simple as an intake gasket or a water pump.

No water flows through the intake.

TieRod, what do you think it might be. I know you know about the most about the big blocks.
