Should you drive your car with a Blown Head Gasket?

If you are thinking a question in your mind “Can anyone drive their can with a blown head gasket”, then we say no. You should not drive your vehicles when you have already known about your head gasket leak. You should have understood what can be happened with you if you drive a vehicle with a blown head gasket.

The head gasket is a part of the vehicle’s combustion chamber that is placed between the engine block and cylinder head of vehicles. When you are driving with a blown head gasket that time the combustion gases push into your coolant and another wrong place. And engine coolant becomes hot that time and it really can be a danger of driving with combustion gases or fluids in the wrong places.

If you are driving with a blown head gasket, it will because of damaging your piston ring, sensors, piston, and cylinder wall that you will lose your money repairing these parts as well.

When you are driving with a head gasket leaks, during the time engine oils will be bear out from the leakage; and rapidly lubricate ended over that leads to damage bearing and requires to rebuild your engine losing your valuable money.

For all of these reasons, we don’t encourage you to drive your vehicles with a blown head gasket. And our experts suggested you when you are looking at the symptom of a blown head gasket, after confirming take immediate step to solve head gasket problem.

Why do cylinder head gaskets fail?

Basically, the reasons behind a blown head gasket is that a head gasket was made to hold back huge pressure of its intake vacuum. And the other is to the design of the cylinder where the placement of valves, cylinders, and other equipment in the head with only be a small portion of bolts which is needed to secure the head from keeping head gasket seals or flat. The small number of blots is said as the main cause of uneven stresses and heavy pressure on the head. The Head gasket holds lots of pressure in the time of the combustion explosion. During the heavy range of temperatures, sometimes it has started mile on a certain time. So, it has to coolant the engine at the time of extreme temperatures.

For all the reasons, it is difficult to say exactly why the head gaskets fail. Even normal driving is also possible cause to blown the head gasket. But the most relative cause that we found is an overheating engine or extreme level of temperature.

If you are really looking to avoid the head gasket failure, you can take the step to keep your engine coolant as much as possible. Time to time, you have to follow-up and observing your vehicle’s water pump that it’s work properly or not. If you drive your car with turbocharger, you also should have given proper attention to its boosting capacity as well. If you observe that the turbocharger boosted more a normal level, you should take the step to come back to it on a normal level. Because the extreme level of boosting will be the reason for creating heavy pressure for the cylinder head and the heavy pressure may be the cause of head gasket failure.

Another way of keeping your head gasket safe from damage or failure is avoiding downshifting with a manual transmission. The way will extend the life of the vehicle’s head gasket. Thought downshifting may be helping you to save your car’s brake, it creates a huge pressure of the cylinder head that will be responsible for failing head gasket.

To avoid failing head gasket, you can try all of these things that we discuss above. But if you see that already your head gasket has blown, no need to worry too much as you think. There are two ways to overcome this problem.

  • First one, you can replace your whole head gasket with a new one; that will be expensive and you have to effort a high repair bill as well.
  • The second one, you can use the BlueDevil Head Gasket Sealer to seal your head gasket leak permanently that will be the best solution for you the purpose of fixing the head gasket that is safe and very easy to use.

How do you know if a head gasket is leaking?

There are some models of cars from renowned manufacturers with a bad reputation for a head gasket. If you have already bought a car between these models, it’s not mean that you lose your whole money to buy the worst car. Though the model has a problem with its head gasket, the car will be good for another purpose. You just need to know how to fix the head gasket problem if you face. Before fixing the problem you have to identify the problem. Here, we discuss some symptoms that will indicate you to blow the head gasket.

The head gasket of a car forms a seal between the cylinder head and the engine block. Basically, it seals the cause of the combustion chamber as well as your engine’s coolant passages. That means the head gasket will be sealed from both high level of hot temperature into the cylinder as well as cold ambient temperatures.

A large portion of vehicles are blown the head gasket from an extreme level of the hot atmosphere on the engine and at a first look, it is hard to identify the head gasket seals without disassembling the car’s engine. Though it is not easy to diagnose a blown head gasket, you have to know other symptoms so that you can properly diagnose and identify a head gasket problem.

Symptoms of Blown Head Gasket:

  • Coolant leaking from the bellow part of the exhaust manifold
  • Look at the exhaust pipe seeing white smoke
  • Frequently overheat your car engine
  • Look at the coolant overflow tank or radiator seeing bubbles
  • Extinguish the white milky oil from cylinder
  • There can be no visible leaks of head gasket but have some significant loss of coolant

symptom of gasket failure

There is only one external visible symptom of a blown head gasket that is coolant externally leaking. Most of the time the head gasket leaks will be between the coolant passage and combustion chamber of your engine. Upon combustion, the gases with extreme pressure will pass into the coolant passage and sometimes the process makes your car engine extreme hot as well.

Combustion chamber it the cause of dropping the engine coolant level that mixed with oil making a white milky substance. When you see these types of white milky substance you should check your head gasket immediately. If you are checking that white smoke exists in your exhaust pipe which will be the sign of a blown head gasket. But remember that on a cool day, a cold engine will be created a small amount of water vapor that is also responsible to create white smoke on the exhaust pipe. If you feel the smoke on the exhaust pipe spread a sweet smell, then it will be the symptom of a blown head gasket problem.

During the time of the combustion process, there is creating high pressures that push the exhaust gases into the engine cooling system. The exhaust gases circulated through the radiator into your engine, and for this reason during the normal operation time car engine will remain under pressure. Check your radiator or coolant tank if you coolant overflow tank you will see bubbles on the head.

Normally it is not enough to prove you have a blown head gasket if you find one of these symptoms, but you see multiple symptoms at a time you should take a step because possibly you have a head gasket leak. It is a little costly to replace the whole head gasket. We found out the most effective solution with the lowest cost that is BlueDevil Head Gasket Sealer that is very easy and safe to use.

How to change a head gasket?

A head gasket is responsible for the internal combustion process and mixing the engine oil and coolant together as both 2 fluids pass from the engine block to the cylinder head circularly. Actually, a head gasket is not too expensive but there needs a big money to repair and replace a new head gasket. Because repairing the head gasket is needed to undertake the difficult technical operation of removing the car engine’s head. The estimated time to repair a head gasket is almost 5 hours.

Replacing a head gasket is not as like as the average job you can do yourself. It is rare that a blown a head gasket due to old age. The most popular culprit in damaging a head gasket are engine overheating, engine pre-ignition or detonation which leads to whole engine damage after a period of time. You have to keep the cooling system in top working order and make your engine working correctly to prevent head gasket failure. Remember, a good thermostat or coolant hose is demand as a little pricey to replace, but both are caused by a thousand dollar engine damage if you don’t choose quality thermostat or coolant hose for vehicles.

A Head gasket replacement procedure is more difficult than you’re thinking. Without getting proper knowledge and practical experience, you should not try to replace a head gasket. We recommended that you should consultant experts surround yours for servicing your vehicle. The following our experts giving some general tips and tricks to change or replace a head gasket.

Part 1 out of 4: Gather necessary information and materials

There are needed to collect some following materials, for the purpose: vehicle service manual (gathering the important information of the model of car and also included some repairing procedures as well), timing belt kit, spark plugs, valve cover gasket, torque wrenches, safety glasses, gloves, mechanic’s toolset, exhaust manifold gasket, intake manifold gasket, engine coolant, engine thermostat, drip pans, engine oil and filter, code reader (optional), container for coolant and a cylinder head gasket.

  • Note: The design of engines varies from car’s model to model. So, to know the engine size and design is very important. Because based on engine design the component is also different.

Part 2 out of 4: Disconnect or Remove all components

Step 1: Need to disconnect the battery at first. It is very easy, just unfasten the black cable from the battery then pull out the battery.

Step 2: Now need to drain the engine coolant and engine oil from the engine. Opening the oil drain plug or port, drain the engine oil. Loosening the lower radiator hose, drain the engine coolant.

Step 3: Need to remove all the components from the cylinder head carefully. If you are a totally newbie, it will be a great idea to take pictures of removing every single part so that later you can reassemble the engine without any hesitation.

  • Note: you have to get the head gasket as starting the involved process. Before removing, you should have the index and mark everything on the toolbox. You don’t need to remove the head, manifold, and intake separately because you easily can remove all these things as a unit. A service manual is a too much important tool, be careful and always you should consult a service manual.

Part 3 out of 4: Cylinder head assembly

Step 1: For checking the flatness, you should look at the engine block and head. We know that the service manual has provided the specification for the engine block and the head. If you find that the engine blocks and heads are out of specification you must need to send out the nearby machine shop to the purpose of repairing.

  • Warning: Be careful not to use anything or any tools that will remove metal. You should use a scrubber pad mounting surface of the head; because it will be created the sealing problems if the surface becomes irregularities.

Step 2: After inspecting the cylinder head, now you need to clean the cylinder head and engine block perfectly.

Step 3: You should clean the threads. Sometimes dirt or rust can exist on the threads. You can easily clean the threads using a tap on the head bolt holes.

Step 4:  Now you have to chase the head bolt with a thread chaser. To blow out straggler you can use compressed air as well. You should have given focus on head bolt torque because torque readings are possible thought any interference.

Part 4 out of 4: Re-assemble and installing

Step 1: To clean the engine block, you can use copper sealant spray (available on your nearby local machine shop) the both sides of the cylinder.

Step 2: After cleaning the engine block with using a spray, you should install the cylinder head.

  • Note: Follow the correct orientation to pre-fit or replace the new head gasket. You should not use sealant unless the service manual doesn’t specifically give any direction. Follow the service manual where the manufacturer will outline the sealant requirements and placement.

Step 3: Now you have to replace all parts that were removed in Part-2.

  • Tip: For remembering all setup, you can consult with your taken notes and pictures which you took during the time of removing. Make sure to clean all parts before re-assembly.

Mechanical Timing is needed for the engine camshafts and crankshaft together. Activate the camshaft so that the valve train can run properly. If you see mechanical timing does not work properly, the possible reason will be the piston contact the valves.

Step 4: Before connecting the battery, check again all setups. Firstly install the positive cable then the negative one.

Once you feel all assembly was perfectly done, refill the vehicle’s engine with oil by using a new filter. Then refill the radiator with engine coolant inadequate level. Before starting the engine, you should have bled the cooling system.

Step 5: Recheck everything for any faults.

  • Note: Follow the tightening sequence that is very important and key factor of proper head gasket sealing. You also should have to follow the torque instructions. If required, you must use new bolts to maintain a tightening sequence. Before installing, you have to coat the head bolt and fill the head with some engine oil.

Step 6: In the last step, start your vehicle; and maximize heat by setting the climate-controlling system. The system helps to remove all stubborn air bubbles by allowing coolant to pass the heater core.

  • Note: Periodically check the cluster of the engine and clean up your vehicle’s engine. Gather knowledge about the symptoms of a blown head gasket so that you can immediately markup the problem.
