Re: Replacement of the cydnr head gaset = $825
When water leaks into a combustion chamber, it sort of steam cleans it. When you take apart a motor with a cracked head/failed gasket, you can tell wich cylinder had the leak because the piston or pistons the water was getting to will appear cleaner than the others. The spark plugs steam clean too, where they will look cleaner than the others that arent getting rained on. Ive heard of people actually feeding their engines water, as a method of cleansing them. Really overheating is all you need to worry about, unless it starts to run rough. That would be a sign the leak is becoming bad enough to cause the compression to become lower on a particular cylinder. Usually(unless its not a bad crack or leak) you can see the compression leaking back into the water works of the engine, meaning with the engine cool and the radiator cap off, you can witness bubbles coming back up into the radiator with the engine running(cool). They make some stuff you can put in it to help solve the leak, but it only works for a little while(if at all), and ive been told its not good on other parts of the system, such as the heater core. Typically, water settles inside the combustion chambers after the car has been shut off. You should be able to pull the plugs out and catch one or some of them with moisture on them. Remember that the engine heats up even more after its shut off, when the water stops circulating. A good time to check the plugs is after a normal drive, and the engine has cooled off almost, but not completely.
