??? Your guess is as good as mine. I checked the level again tonight and the radiator is still full but the level in the resivor is 1/2" lower since sunday. I am calling the dealer in the morning and get me a appointment on sat morning.

 

Good idea. That's a bummer. Things like that shouldn't be happening to such a new truck:mad2:

 

They put some dye in it today and told me to drive it for 500-1000 miloes and bring it back in so they can look for the dye and see where the antifreeze is going.

Just an idea, but your levels are not that high in your UOA. Are you perhaps checking your oil with a coolant soaked rag on a regular basis? Did you add oil from a container that once contained coolant? Also, for the leak-check the tightness of your heater hose above the turbo. Just a few ideas...

 

Especially at the dip stick seal, oil fill cap and crank case vent. Any place steam can escape this milky substace will collect.

 

I took a new oil sample tonight and it was really runny and had a sort of bubbly mixture on the top of the sample. I also checked my antifreeze level in the overflow. I marked it cold a few weeks ago and it was hot today when I checked. It was about two inches lower than the mark. I am sending off the sample in the morning, I hope that they can get to it fast so I can find out if the antifreeze is going in to the oil. "give:

 

Let's hope for the best.

 

So if it is antifreeze, what is the cause...head gasket?

 

Most likely. Could also be a crack in the block, but it's rare.

 

Still waiting for the analysis to get back. I think that there is a problem though since the truck is starting to make wierd noises and run like crap. I am hoping for the best but fearing the worst.
