One such vehicle has such a bad reputation for head gasket bug there is a group of owners trying to get the manufacturer to take a recall on them. If you happen to ain one of these vehicles, don't worry it does not mean that you have a bad car or that you are going to spend lots of coin.

What is a Head Gasket?

Let's start past talking about what a caput gasket is. The head gasket lives between your engine block and cylinder head. Every modern car has this gasket but they vary in their thickness and construction based on the manufacturer's design of the engine. The caput gasket is and so important considering it seals the combustion sleeping room allowing your automobile to build the proper pinch and contain exhaust gases both of which aid in maintaining the efficiency of your engine. The head gasket also keeps coolant and oil out of the combustion chamber which is important for the aforementioned reasons y'all wouldn't want coolant or oil leaking anywhere else.

Since a visual inspection normally will not prove a caput gasket leak, it is important to know the other symptoms so you can accurately diagnose a caput gasket problem.

How To Tell if a Head Gasket Is Blown:

Coolant leaking externally from below the exhaust manifold
White smoke from the exhaust pipe
Bubbles in the radiator or coolant overflow tank
Overheating engine
White milky oil
Fouled spark plugs
Low cooling arrangement integrity

External Head Gasket Leak

A head gasket leaking external would cause coolant to come from beneath the intake or exhaust manifold and oftentimes merely happens when the engine is completely warmed upwards. If at that place are no other cooling passages or hoses nigh the head gasket you may be able to positively identify the leak as a caput gasket leak, but if there are other cooling passages nearby, you may need to add a UV dye to the coolant and then watch the head gaskets with a UV lite to positively identify the leak.

White Smoke From Tailpipe

Almost head gasket leaks are internal to the engine allowing coolant to flow into the combustion chamber on every intake stroke. When this happens to coolant burns/evaporates with the combustion process and appears as white smoke coming from the tailpipe. This smoke can be differentiated from moisture during a cold commencement by a sweet scent and will go along even when the engine is warm. If the leak in the caput gasket is large this white smoke can oft be excessive and breaker from the tailpipe.

Bubbling in the Radiator

Besides allowing coolant into the combustion chamber, an internal caput gasket leak allows exhaust gases into the coolant. This can crusade bubbles to be in the radiator or coolant reservoir making the coolant look like it'south boiling fifty-fifty when it'south cold. The bubbles are exhaust gases that force their style into the cooling organization during the combustion process.

If your engine overheats it can crusade lots of problems. The biggest concern is the expansion of metal components past what they were designed for which tin can cause cracks and warping. Also, it tin permanently impairment seals and gaskets cause other leaks in your engine. Both of these bug often crave a full engine rebuild to remedy.

White or Milky Oil

As coolant leaks into your combustion sleeping room, it will seep by your piston rings into your oil. Over fourth dimension oil and water volition mix and cause the oil to turn a milky white. You can await for this on your dipstick and effectually your engine oil cap. Having h2o in your oil will make your oil ineffective in properly lubricating your motor which volition quickly permit vesture on your cylinder walls and on the creepo and camshaft bearings.

For example, a "V" fashion engine has 2 heads and information technology is best to supervene upon the gasket on both so the cost increases significantly over an inline engine. Similarly, an engine with overhead cams adds the complexity of removing the timing chugalug or chain which makes the job more complicated than it would exist on a pushrod engine where you just need to remove the rockers and pushrods. Automobile work tin add lots of cost to a caput gasket job so knowing how much damage has been washed to the head or block is of import in computing the cost of your head gasket repair.
