2005 Subaru Baja - 2.5L 4 Cylinder 103,000 mi,
I just spent $2500.00 to replace head gaskets, timing belt(required maintenance), water pump, idler pulleys and belts and hoses while they were in there......even 8yr/100K should have been extended because my vehicle has passed the 8 year limit...Subaru KNEW there was a problem and the only solution they gave was to put a "conditioner" in the coolant when you changed the antifreeze...I DID that also...this "conditioner" was nothing more than stop-leak sold in any parts engine was leaking oil from the head gaskets but the leak got so bad, I could smell burning oil while I was driving and there was a spot on the floor after each drive....I know Subaru would say, just get a new vehicle after so many years on a vehicle but that is not the point of this discussion...besides, Subaru doesn't make anything that resembles a Baja anymore and the outback and forester or Crosstrek cannot compare to what I would have cost Subaru a small fortune to replace all the bad head gaskets out there BUT that is there mistake not the consumer's fault.....with all the problems at all the other manufacturers, you would have thought that Subaru would have stepped up a little bit more than they did...I know my car is good for another 100K engine wise because I got GOOD head gaskets but who is going to replace the $2500 bill???? for poor quality????

Bought a used 2004 Baja. had been jury rigged for sale, but engine was bad due to blown head gasket. Had to replace engine.

During past 650 miles and 1 1/2 mo. (last oil change 49379), oil has gone to nearly out twice and coolant to lower third once. "check engine" code said catalytic converter out and I was told it could be from broken head gasket. There's no oil leaking underneath. Are these problems related and where is oil going? I'm not driving it because check light stays on.

Told about the head gasket leakage at my last oil change this week and the 72000 check up.
2003 Subaru Baja - 2.5L 4 Cylinder 98,000 mi,
My car has been overheating for quite some time. The first thing I did was take it into the dealer, to have everything checked out. They told me I had small droplets showing around the head gasket, but it was nothing that had to be done right away - that was at 98,000 miles! Since then, I've had the radiator replaced, the timing belt, the water pump, and the thermostat ........ I'm furious about this report.

While driving my Baja I noticed the temperature gauge seemed a little higher than normal last spring. Then this last Summer started noticing a hot oil smell coming through the vents and around the engine after driving. After seein oil spots on ground, I had engine bottom completely clean to see where the oil leak was coming from. It has been diagnosed as a failing head gasket. Mechanic is putting together an estimate.

2006 Subaru Baja - 2.5L 4 Cylinder 97,500 mi,
Head gasket leak found while having timing belt replaced. Guessing I don't benefit from the warranty extension being the second owner. Have to look into cooling system fixes to prevent recurrence. Anyone done this yet???
2003 Subaru Baja - 2.5L 4 Cylinder 58,630 mi,
I was driving with the a/c on when the temp guage rose to the "hot" area on the dashboard and the a/c turned warm. I turned the heat on high until I could reach a service station. After adding coolant the problem seemed fixed. I asked around about it and was told to have the collant flushed and replaced which I did. Now I've noticed my driveway is wet under the car. Not a puddle just wet. I also have to add coolant from time to time to replace what is leaking. What should I do?
2005 Subaru Baja - 2.5L 4 Cylinder Turbo 156,000 mi,
Head gasket replaced at approx. 100,000 miles. About three weeks ago, the gasket started leaking. Since the cooling system problems have not been addressed this problem may surface again.
