Yes, replacing a head gasket can be quite expensive, typically ranging from $1,000 to $2,500 or more, depending on the make and model of the vehicle, as well as labor costs in your area. The procedure is labor-intensive, as it often requires removing multiple engine components. Additionally, if there is significant engine damage or if other parts need to be replaced, costs can increase further. It's important to get a detailed estimate from a qualified mechanic for an accurate assessment.

Your cylinder head gasket needs replacing.
It could, if the old gasket had failed.
Depends on where you live. This is a major repair and is expensive. I would guess from $300 at a minimum, if nothing needs replacing except the gasket. If the head is cracked or wrapped, then it will cost more.
The head gasket itself isn't actually expensive. The labour of taking the head off and back on is the expensive. For example when I did my car it was £60 for the gasket and if I was to go to a garage they would of charged £200 labour.
Resurfacing the head of an engine is necessary when replacing the head gasket. An improperly surfaced head will not allow a tight seal and can result in a costly repair.
No you do not.... the valve cover only bolts to the head, and the head bolts to the block... True- these are two different jobs. When changing your valve cover gasket you may just want to ensure that your head bolts and lifters are still torqued down properly. Otherwise, DO NOT remove the head gasket if you simply want to change the valve cover gasket. when replacing the head gasket you should replace the valve cover gasket and may need to (depending on make & model) replace the egr gasket, intake mainifold gasket, and exhaust manifold gasket ...but not the other way around. If your replacing the head gasket ask your local auto shop if they carry a head gasket kit that includes everything necessary in one box...but if your just changing the valve cover gasket then just change that.
