Hi there:
In general, the tips you’ve listed are very important to remember, but you are missing on very critical step – purchase a 2001 Honda Accord service repair manual and follow their specific instructions exactly. Also, if you’re completing this repair due to overheating damage; you might want to replace all ignition system sensors and connectors as well, including the crankshaft position sensor and ALL electrical connections going to those sensors.

The average cost for a Honda Accord Head Gasket Replacement is between $1,491 and $1,758. Labor costs are estimated between $834 and $1,052 while parts are priced between $657 and $706.
How Much Does it Cost to Replace a Head Gasket? According to a national average, it costs between $1,624 and $1,979 for a head gasket replacement. The associated labor costs are estimated between $909 and $1147 while the parts themselves vary in the range of $715 and $832.
Replacing the gasket can take anything from six hours to a few days, depending on the severity of the failure. A blown head gasket is one of the biggest failures your car can suffer, and to fix it properly takes time.
If your car can run safely for longer than 15 minutes without overheating, there are chemical repair products designed to seal the leak without the need to disassemble your engine. In fact, even those with hardly any mechanical knowledge can install the fix themselves.
Water in your oil will allow your bearings to rust and wear out very quickly. If your head gasket leak has caused this problem you are almost always better off replacing the whole engine as a new head gasket will stop the leak but bearing damage has probably already been done.
If the body of the gasket loses load and leaks coolant into the oil ports, bad things happen. The oil will be compromised in its lubricity, resulting in possible damage to the internal engine parts. It may also result in excessive heat and other failures. This requires replacement of the head gasket immediately.
The short answer is yes, but it is not recommended. Ignoring a blown head gasket will likely lead to more damage to your engine as well as your wallet. Gaskets are some of the most important and necessary parts of any engine which function to seal off compartments.
When you compare the basic services, repairing a blown head gasket is always the least expensive initial repair. The problem is that most of the time, when a head gasket is damaged, other components like the cylinder head itself, pistons, and cylinder head hardware are often damaged as well.
The answer is, they should last as long as the life of your engine. However, if you don`t properly maintain your vehicle or the engine, chances are you`ll be having the head gasket replaced in your vehicle`s lifetime.
The Steel Seal Blown Head Gasket Fix Repair Sealer is our top pick for the best overall permanent head gasket sealer. It works well on older and new vehicles and is suitable for cars, vans, SUVs, and trucks. If your budget is a little tight and you still need a professional-grade sealer, check out the K-Seal ST5516 HD.
A blown head gasket is a serious issue, as mechanical problems in the vehicle may have caused the problem and will need fixing. In addition, the head gasket problems may have caused engine failure or serious damage to the engine components, and that situation will need addressing.
Steel/Multi-Layered Steel (MLS) gaskets are designed to handle higher compression ratios, special cam timing, and higher operating temperatures, so they`re ideal if your engine is supercharged, turbocharged, or hooked up to nitrous oxide.
Other items that will likely be needed to complete a head gasket replacement include coolant, maybe oil, oil filter, spark plugs, hoses and new cylinder head bolts.
If the head gasket is damaged, the engine will quickly overheat and serious damage will be caused. Overheating in the engine of your car will lead to a loss of compression, the mixing of oil, water, coolant as well as a reduction in lubrication.
Is it a big job to replace a head gasket? The head gasket separates the two main components in an engine, the block and the cylinder head; it, therefore, takes quite a large amount of time to complete a replacement.
Head gasket thickness will impact Compression Ratio. Changing gasket thickness can be used to fine-tune compression. However, the gasket`s thickness will also affect its ability to seal the combustion chamber and oil and coolant passages. For most engines, we recommend the OEM gasket thickness.
If you`ve got a small head gasket leak it will cause your car to overheat but not all the time. The overheating is often due to a loss of coolant but can also be due to the extra heat the head gasket leak is adding to your cooling system.
Some common signs of a leaking head gasket include: Coolant puddles under your vehicle. Low coolant level in your reservoir. A strong, acrid smell when your engine is hot – some describe this as a “sweet” smell coming in through the car vents.
Why Does a Head Gasket Repair Cost So Much? As with any expensive car repair, labour costs are the main culprit. The actual part doesn`t cost very much, but a repair can take up to 10 hours. It`s very difficult to get to your head gasket because you need to disassemble the engine to complete the repair.
Head gasket failures are usually the result of engine overheating, so ensure coolant is topped up and the coolant system is in good working condition, with no leaks and an efficient radiator. A properly-installed head gasket will also prevent future damage.
Most engines will blow a head gasket when the coolant temperature has reached 260 degrees or more.
Which is the best head gasket sealer for Honda vehicles? A specialist head gasket sealer and radiator leak repair, K-Seal is designed to prevent head gasket, coolant and radiator leaks in your Honda by sealing up: Holes up to 0.635mm / 0.025in in diameter.
Is head gasket sealer safe for my engine? Yes. Because the particles used in K-Seal are so small, they can only seal holes that are up to 0.635 mm in diameter, so if they manage to find their way down passages in the heater core or radiator, they won`t have any effect on them.

i have a 1994 z28 and i did a head gasket replacement for some blown head gaskets. I then tried changing the timing gears and when
ANSWER : Hi there. It really depends on the location of the motor (meaning if it’s installed in the vehicle or loose and on an engine stand), that would factor into the price and whether this is a project one of our mobile mechanics can complete. We can complete the oil pan gasket replacement, but some of the other jobs like wiring harness, intake and rocker arm installation is outside of our scope of service. In regards to estimates for those services, I would suspect it would cost anywhere from $400 to $1,000 based on where it’s completed and what supplies would be needed.

How to check which (valve/head)gasket is not working& what is the price to fix head gasket ?
ANSWER : The problems you describe (leaking radiator, overheating) often lead to a "blown" or leaking head gasket. For your vehicle, there is only 1 head gasket, which would need to be replaced. This is in addition to any failure of the radiator or other cooling system components.
I recommend having a YourMechanic mobile, professional mechanic come to your location and perform a car is overheating inspection. This inspection will identify failed cooling system components (radiator, head gasket issues) and recommend/quote needed repairs.

Mechanics replaced water pump but did not replace the thermostat. Engine overheated and blew the head gasket? 2010 Jeep Compass
ANSWER : Hello – this is a judgement call. It is common practice, but not a "standard", to replace the thermostat when replacing the water pump. This is mainly due to access to both easily when replacing either one, and the relatively low cost of a thermostat. Thermostats do not have "wearing" items like the bearings in a water pump, and can outlast a water pump. They can, and do, however, fail unpredictably (close down tight) – sometimes. I have experienced this personally. I encourage my friends, relatives, students, and customers to replace both when repairing either – save the labor cost of a 2nd repair, and the somewhat unusual cost you have sadly experienced.

Is manifold gasket replacement a diehard requirement for manifold r&r?
ANSWER : The intake manifold gasket can be reused if it is not damaged in any way. The cost of the new gasket versus removing the intake again if it leaks is something to think about. Consider if it’s worth the risk to reuse it if you had to do the job twice. The manual for your Pontiac Grand Am says you can reuse it as long as it is not damaged, but I personally would not reuse it.
If you need some assistance with this, consider YourMechanic, as a certified technician can come help you with the repairs you’re making and service your intake manifold gasket as necessary. Good luck.

Head gaskets particularly problematic
ANSWER : Regularly scheduled preventative maintenance is generally the best way to stay ahead of head gasket problems. Old and corroding engine coolant can buildup in the coolant passages of the engine (due to electrolysis), this can cause the head bolts to erode and can also block the thermostat. Old coolant can also lead to overheating, which is the number one cause of head gasket failures. In general, coolant should be replaced every 45,000 miles or 5 years, whichever comes first. A local mechanic (like those at YourMechanic) can also perform a coolant test with a refractometer a your home or office. A refractometer test shows the protection level and dilution of the coolant.

Truck won’t start after replacing head gasket
ANSWER : Hi, the way to tell if it was assembled incorrectly is to do a compression test on the engine and see if you have compression on all cylinders. You may have timed the engine incorrectly and this would show up as having low compression. This engine may have been damaged because it was timed incorrectly, an example of what might have happened include, bent valves and other possible engine damage. I recommend you have a mechanic, like one from YourMechanic, diagnose why your vehicle is not starting to avoid any further complications.
