It's a furd 1.9 engine. Back in May, one of the freeze plugs in the head decided to rot out. By the time I noticed it (approximately 2 days later) the hole was about 3/8" in diameter. On its first symptom showing day, the temperature gauge bounced from cold to the middle of the normal range, but never "Hot". Its second and last symptom-prone day, I noticed puffs of steam from under the hood, but never saw water in the engine compartment. After the car got towed home, I dove into the engine compartment with flashlight and mirror in hand. I saw the hole and realized that I ran in VW mode (air-cooled) for two days. From what I have read online, these heads do not like any type of overheating and will crack and / or warp in no time. I gambled with just the head gasket... and lost.
