Well i was checking a car that i might be buying today, and i noticed that in the coolant reservoir tank there is a bunch of white grease like stuff...I'm guessing oil is mixing with the coolant, therefore the head gasket is gone? Anyone have any experience with this? Thanks.

 

Thats what it sounds like.... check the oil too and see if there is white in that.

Don't buy it, even if they tell you it is silicone water pump lubricant.

Agree with all the above... don't walk away, RUN (that's twice just this morning I've got to say that...lol)
