Depends on the make, model, and engine size. Can be as little as $300 to as much as $1,000. Of course a 4 cylinder with one head is the cheapest to repair. A V6 and V8 are the most expensive due to 2 heads.
Head gaskets are expensive but can disable a car if not treated. The cost for a new head gasket for a Toyota is $177.12.
There are many gaskets on any car engine. If you are asking about head gaskets, they are between the cylinder head(s) and the engine block. The cylinder head is under the valve cover. --------------
Short answer, remove the heads and replace the head gaskets. If you want to know exactly how to do this, then purchase an Hayne's or Chilton's repair manual for your car.
Yes.

Only insofar as they're almost impossible to do with the engine in the car. If the engine is out, they're no worse than any other V8.
it means you have a cracked head or blown head gaskets. does the car overheat?
Water is in your engine. Check intake and head gaskets.
it's probably the head gaskets.
2002 Grand Cherokee with the 4.7 V8 engine head gaskets replacement would run aprox $1500 to $1800 parts and labor depending on your location.
That depends on the age of the car..the number of miles and how much the car is worth versus how much it costs to have the work done...do if you have a twelve year old car with 125000 miles and it's only worth 1500 dollars....and a head gasket job costs $400...then is that car worth about 2000 dollars to you??? And if the head gaskets are blown, chances are, that there are several other issues with that car..blown head gaskets are usually due to poor maintenance or abuse. Is the risk worth the expense if the transmission is probably going to go out soon...or if the car was driven for a while with the blown gasket...then your probably also going to have the engine seize up soon because the engine oil was contaminated with engine coolant and the bearings are now in really bad condition...always be aware that something as severe as a blown head gasket can lead to other serious repairs.
No, impossible. the head gasket cannot be affected by a pothole unless the engine fell out and the rest of the car drove over it.
