Editing Head gasket

Head gaskets provide the crucial seal between the engine block and the cylinder head. It seals all of the combustion chambers, and prevents coolant and engine oil from leaking into the cylinders.


==Different types of head gaskets==

==Aluminum cylinder heads==
Though aluminum is lighter than cast iron, it expands faster. This quicker cycle of expansion and contraction stresses head gaskets.



==Symptoms of a blown head gasket==
*Foaming or bubbling coolant.
*Rapid pressure buildup in cooling system, before engine is warm.
*White smoke in exhaust.
*"Milkshake" oil.
*Oil in coolant.
*Low cylinder pressure.

==Reasons why head gaskets fail==
*Some blocks are more prone to head gasket failure, because the bolt positioning applies uneven pressure

==If you have a blown head gasket==
Check to make sure your heads and block are straight. If they're warped, you could end up with another blown head gasket.

==Suppliers of head gaskets==
*Fel-Pro
*Mopar Performance Gaskets (check)
