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. STOP driving this car immediately or you will do serious damage to the engine.

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.
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.
If you ran your car too hot you may have warped the head which would cause your head gasket to leak water or oil. You need also to hone the heads to make them flat again.
If the vehicle does not have any bad head gasket symptoms like fluid loss or cooling system pressure build up or white smoke out the tailpipe then the head gasket does not ever need to be replaced.
No, not if it was done correctly and the engine has not overheated. Overheating is the main cause of a blown head gasket.
You will need to remove the cylinder heads. Remove the old head gasket and clean the head gasket surface. Put the new head gasket on and reverse the process.
Absolutely not. There is a problem somewhere such as faulty installation or possibly the surface of the head is warped and needs to be machined. A factory installed gasket is good for at least 150k.
The head gasket has failed and will need to be replaced. The head gasket seals the place where the engine block and the cylinder head meet, there are many oil and coolant passages in that area, so when the gasket blows out the coolant in the nearby passage vents into the cylinder closest to the failure point.
The cost to replace the head gasket is between $900 and $1200. The actual cost will vary between shops as each uses a different labor rate and there could be items that need to be repaired or replaced due to overheating that commonly occurs with a bad head gasket.
It's up there. If you have seepage at the head gasket, you need to replace it.
I replaced the head gasket. How many pounds of pressure do I need to apply to the bolts on the head?
90% sure of it. There is a known circumstance I read about once that could result in oil getting into the engine coolant... Had to be one of the Windstar forums or here at WikiAnswers, since the early 3.8l Windstar engines were so prone to head gasket leaks...In the meantime and back to the more common causes... It could be either a bad gasket or a warped head. Either way, the gasket is going to be replaced.See "Related Questions" below for more
A head gasket set and new head bolts.
Remove the head and fit a new gasket. You may also need the head surface machined flat.
You have a blown head gasket, cracked head, or both. The engine must be taken apart and head gasket & head possibly replaced. If you drove it in this condition for a long period of time you may have totally destroyed this engine and it will need a complete overhaul.
