Well I'm pretty much at my wits end with this car and I'm debating what to do next and would like some peoples opinion. I have the 2005 limited, I'm purchasing a head gasket leak down detector test but I'm %95 percent sure it's blown, just replaced my radiator, after my last one exploded. Refilled with new fluid and drove the car for about a day or two. Low coolant light came on, checked the res its low, light milky substance on the cap at 60k miles getting ready to inspect the oil. I'm sick to my stomach... So what are my options, new head gasket but from my understanding if the damage is to extensive I'm better off getting a used complete motor?
