Automobile engines consist of two major assemblies, the block, and the head(s). The block is the major part of the engine, housing the cylinders, where the pistons are, and the crankshaft, which transfers power from the pistons to outside the engine. The head contains the valves, which are used to seal the cylinders between strokes of the pistons. Through the valves pass the air used for combustion, and the spent combustion products, which travel out the exhuast.
The head gasket is the seal between the head and the block. It is subject to very high pressures and temperatures, and also expasion and contraction as a result of temperature changes.
AnswerIn addition to the above great answer, may I add. Normally a head gasket will never leak. If it does then it is because of a defective gasket, incorrect installation, warped head, and the number one cause, overheating of the engine. Most engines today are made of aluminum. Aluminum does not handle excessive heat very well and as such is very susceptible to blowing the head gasket when the engine gets too hot. Once the head gasket leaks, it will allow coolant to enter the combustion chamber and or the oil pan. This will destroy the engine if not corrected.You have a blown head gasket or a cracked head. STOP driving this car immediately or you will do serious damage to the engine. It will need the gasket replaced and the head checked.You have a blown head gasket or a cracked head.

No additive is going to help - you need to get your head gasket replaced.
The head will have to be pulled and the gasket replaced. If the car overheated the head may have warped and will need to be resurfaced or replaced as well.
no
hi if you replace the head gasket you will need to have the head repaired and machined as the head alloy eat's out which causes the gasket to fail
It would be recommended if coolant had mixed with the engine oil before the head gasket was replaced.
You need a new Head Gasket.
You cannot determine this until you remove the heads. Either way the heads must be removed and the gasket replaced. After removing the head you need to have it inspected by a machine shop.
There is no set interval. It only needs replaced when it has failed.
If u have water in your oil pan u need to replce it.
head gasket may need to be replaced
Yes. 20.99 at autozone for me yesterday, they are torque specific so they need to be replaced.
