To give yourself the best overall chance of BlueDevil working successfully, in addition to the directions, you should remove the spark plug from the cylinder with the leak; this will be the spark plug from the cylinder with a low compression reading. Yes, a collision could potentially cause the head gasket or other areas of the cooling system to leak. Even with traveling I have to constantly put fluids in it because i will go to the store and come home and before i go anywhere else I have to fill the radiator back up.
Thanks for your question about your Honda Civic. Based on your description, you could have a blown head gasket, but your symptoms would indicate a large leak. If that is the case you should have some other problems like low power and white smoke from the exhaust. Cap both look milky. Will your blue devil product work?

Can this mess my engine up? It has alot of white smoke, and smells kinda like gas inside the car.. Thank you for asking about your Mercury Sable. Based on your description, it sounds like you have a blown head gasket. The product does not contain any solid or particulate matter, so it would not clog up the engine.

I noticed a knocking in my engine about a month ago and now this. Should i look for any other signs and does this Sound like a blown head gasket?
Based on your description, it is possible your vehicle has developed a blown head gasket. The knocking sound coming from your engine may be an indication that you are getting water into your oil, so we would recommend checking the oil and changing it if necessary. If you are leaking oil from the head gasket, the product would not be able to help with that issue. Hi, my Tata Indica overheated in August, whereafter the mechanics I called, filled up the water and drove it back to their workshop.
They replaced the thermostat housing, the water pump, placed a second hand radiator, filled up with anti-freeze and put a new thermostat. Now, not even two months later, it overheated on my way to work last week. I was a lot further from home and they once again filled up with water and drove it back to their workshop. Now their quotation states the head gasket had blown, they need to have the cylinder head overhauled, replaced the fan switch and replace the thermostat again.
Does this diagnosis seem correct? Can driving my vehicle back have damaged my engine more — even if they kept the water filled up?
Thank you for asking about your Tata Indica. Based on your description, it is possible that when the vehicle overheated the first time, it caused a head gasket leak. It seems like over time, the leak may have gotten worse, causing the head gasket to blow.
Continually filling the system up with water would not have been able to remedy the issue if the head gasket was already blown. I purchased a Subaru Outback 6cyl. Within a week, I noticed not a drop of coolant in the coolant reservoir bottle and I could not see any coolant in the radiator, add about a litre of water to both radiator and the res.
Since then, the the car dealer put in red coolant in. It overheated the same day. The coolant rises in the coolant res. Air bubbles can be seen rising in the coolant res. Coolant has been bleed of air twice, no effect. A number of mechanic mentioned head gasket. A coolant specialist said it was a blocked radiator?? If using you head gasket product, do we need to correct the problem that caused it in the first place?
Needing help. Thank you for asking about your Subaru Outback. Be sure to follow the guidelines for the proper amount to use based on the capacity of your cooling system. I have a ford escape my check engine light has been on it not over heating to my knowledge it give a reading of one of my cylinders but the mechanics said something about a vale it had a miss as well as sometimes jeering really bad sometime then my check engine light will come on is this a sign of a blown head gasket.
Thanks for your question about your Ford Escape. Your mechanic is correct that a misfire code could be an indication of a blown head gasket as cooling leaking into a cylinder could cause it to misfire.
We would recommend checking for other causes of this code first like bad spark plug or ignition coil, a clogged fuel system, or even a bad sensor. Any of these problems would also cause your car to run poorly as well. Hi guys i have opened my engine for changing the engine valves should i change the head gasket as well or i can put the old one thanks.

Well then I received a picture from my friend with a puddle of milky substance that had apparently come from my car.

Hello, Will a blown head gasket drive out all the coolant in about twenty miles. There was a two hour stop in the middle of the trip. The radiator was full at the start of the trip. The radiator cap was not fully tight due to a suspicion of an external coolant leak.
The temperature gauge was fluctuation between normal and somewhat hot on the return trip. The coolant was not visible in the radiator. There is no indication of coolant in the oil but it is past due for a change.
Where was your suspicion of the external coolant leak? Did the engine overheat at all prior to the trip? This morning my oil light came on on my drive to work. By the time I got to work and had a look at the car, there was steam coming out from under the hood, there was a hissing noise and water spluttering out and the engine was incredibly hot.
I got it serviced two weeks ago with there being no problems, so I took it back to the same people to check it. Is it possible that this problem has arisen within the last two weeks? It confuses me that they would not have seen any warning signs when they serviced the car originally?
Thanks for your question about your car. If the oil light came on and stayed on then either your oil pressure sensor is broken or your engine lost oil pressure.
Running your engine with no oil pressure will quickly cause bearing damage and require the engine to be rebuilt or replaced. If your engine was low on oil it very could have caused overheating and blown the head gasket. We would recommend checking to see if any of the maintenance that was done last time could have lead to a low oil or low coolant level as that may be something the shop should cover under a warranty.
Is my head gasket too far in the grave? If the engine is unable to turn over, unfortunately, it may be a little too far gone. In order to get the benefit of using the product, the vehicle would need to crank and maintain idle for a full 50 minutes.

Second, it keeps coolant and oil from mixing as they circulate through your engine near each other.
There are several possible causes, including engine age, but two common culprits are overheating and preignition issues. Overheating: When an engine overheats , the metal expands and pinches the head gasket so it no longer seals properly. A telltale sign of this problem is white smoke coming from your exhaust, which is from coolant leaking around the head gasket. Pre-Ignition Problems: If the timing of the combustion process is off even slightly, it can send too much pressure into the cylinder head.
This can cause the head gasket to fail. If this happens, you may notice the car running roughly, especially when you first start the engine or at idle. Go to front page. Search results Search Haynes.
