Default Blew head gasket?

Guys, this car is beginning to worry me again.

Monday, I took the car out.. she ran INCREDIBLE. The power of this car increased tons, and she just ran awesome. All the vitals were all perfect.. everything normal.

Go out to car, run her a little.. low coolant light comes on the DIC. It'* always been a false alarm, but I check the coolant anyways. Pull rad cap, BAM! Poop. This looks like fresh out my ***, poop. Rad cap has poop.. POOP on it. Coolant colour on top is a milky brown, no solids floating around, but it'* brown. Pull LRH, all clear liquid comes out. Nothing brown. Flush through with water, still clear as can be. I'd drink this water, that'* how clean it was. Fill it up again, run engine, check coolant, nothing poopy, nothing wrong. Check oil, the oil looks a little watery, but the level is EXACTLY the same as it was last night.

I have flushed the cooling system a many times, but crap only comes out when the engine is hot. While the car sat over winter, there was coolant sitting in the block, and it had become rusty. First time I flushed it, the coolant looked fairly similar in colour to what I just saw here, except minus solids.

Somebody please help me out here! I have really no clue about this stuff. I can post pics of everything, I have the paper towels in which I cleaned the rad cap off with, and I can post pics of the wipe off on the dipstick.

btw: my coolant is just straight water.. so it isn't antifreeze..

Eek! You guys scare me.

Ran car, **** appeared after 5 minutes of idling the car.

The car is smoke free, oil is completely free of water [just checked it before running engine, and after, with a clean rag, there is no doubt in my mind that the oil is completely dry.

Is there ANY chance that this is just rust or something? Maybe some **** left over in the block from the winter or anything? Maybe flash rusting? Come on guys, any hope.. can we be positive? A good frame of mind, best case scenerio here?

Drive for a few days and check again, if it stays clear, don't worry about it. If not the first thing I would do is to pull the valve covers and retorque the head bolts then flush and repeat. Simple/cheap stuff first.

That said id you have a leak from an oil passage to a coolant passage (high pressure to low pressure, may not leak at all under 40 psi differential), it will run great but use oil.

You better watch out with your oil in that state, run long enough and you might spin a rod bearing (assuming coolant is getting into the oil passages). As for how long, it'* hard to say. If you're burning any coolant, you'll puff some nice white smoke out the tailpipe (assuming coolant is getting into the combustion chamber) - and it'll smell sweet (like... burning coolant, lol). Smell your exhaust gases.

Usually reserved for 7M owners, but unfortunately, it seems as if perhaps

I forget. Did you end up getting the heads machined like everyone told you to, or did you decide not to?

Also, you really should put in some real coolant. It'* not just "anti-freeze". It'* also anti-corrosion, and ups the boiling point.
