So, here is a long story short..my 2.5 97 Outback is in the shop AGAIN! I and the mechanics are stumped. About two years ago, 6 months after I purchased it at $12,000 (70,000 miles), they found hydrocarbons in the coolant system and indicated to me that I would soon see the infamous head gasket issue arising. I continued to drive it as I had no apparent issues. About two months ago, I had them test the hyrdocarbons again due to the fact the car just wasn't running that well, it was much higher. I decided why not just replace the head gasket before it blew and before I was left stranded somewhere, I was preparing for a month long road trip with the car. I dropped the car off and two weeks later was told that there is a leak in the coolant system but they can't find where it's at. They had it under compression for nearly the entire time, mainly because they didn't know which side could be causing the problem. That was news to me, finding out my car had a double overhead cam as opposed to the single. Yes, I was one of the stupid, excited buyers who did not do ENOUGH homework to find out more about my future "lemon". So, they did not want to tear apart both sides and indicated to me that they just can't tell which side is going bad. They told me my car would have to show it's symtoms before they could fix it. So I drove off knowing I literally have a time bomb ready to go off, a car that is now unrealiable.
In preparing for my month long trip, I decided to take the car on a three hour trip. Two hours into the drive the temp gauge started rising quickly, when I pulled over to check the engine, the coolant was all over the engine and the radiator was empty. The fan did kick on and once water was back in the radiator the temperature gauge would go back down. There was never any steam coming from my exhaust,as the mechnic had indicated would occue nor was there any evidence of water in my oil. So in order to get back home, we drove it continually stopping to refill water. So now the car is back in the shop.
My question, as I have been searching this board religiously, is this indication of a blown head or could it be the thermostat or water pump? Any information would help as I fear the compression test they will perform may not reveal anything. Are there any others ways to find out which head gasket is going bad?
Thank you, thank you....to anyone who had input or could lead me to where I could more similar information.
