Today on my drive to work I noticed a burnt smell so I popped the hood and found a heater hose spewing. I have my heater core bypassed and it was spewing next to the firewall - All over my transmission and spark plug. I found a small cat food can laying around so I put that by it to redirect the flow. (I don't know if the coolant could hurt anything but I figured it was best that it not be spraying over everything.) That didn't worry me too bad. I've had a similar problem with the other hose in the bypass (engine side). I just cut off the faulty piece and there was plenty left. What I don't understand is why there was coolant in it? What is the plastic pipe that attaches to the hose? Apparently it has coolant running through it. Ok, the part that has me worried. Coolant started leaking out of the head bolt. (corner bolt closest to the thermostat housing) I've had a minor oil leak from there for as long as I've had the car. Is my head gasket shot? I need to know what to do with the car. I'm about 10 miles from home. If I fix the hose, fill the radiator with water, and nothing is leaking should I drive it home? Edit: If there was a problem with the head gasket what are the chances I could tell by checking for smoke in the exhaust?
