One of the main causes of white exhaust smoke and coolant loss is a cracked or warped cylinder head, a cracked engine block, or head gasket failure caused by overheating. A cracked head may allow coolant to leak into one or more cylinders or into the combustion chamber of the engine. Dirty coolant, a poorly maintained cooling system, a low coolant level, or a non-functioning cooling fan can cause engine overheating. In addition, engine wear can eventually cause the gaskets to lose their capacity to seal properly allowing internal coolant loss. Intake manifold gasket and head gasket failures are two of the most common sources of internal coolant loss caused by engine wear.
While a cracked coolant reservoir tank is rare, when most mechanics hear about thick white smoke from exhaust, they would assume the worst. That is usually due to a crack in the cylinder head, head gasket or engine block, all of which are not very quick and cheap to replace, and is not a maintenance job for the novice.

One of the reasons for cracks to form on the head gasket is just normal wear and tear. When this happens, the coolant is no longer contained within the cooling channels of the engine but finds its way into the cylinder, where it gets burned. A cracked head gasket cannot be repaired; it will need to be replaced right away.
The first thing to check, you would think, is the head gasket, but before this, you should inspect the intake manifold gasket first. The intake gasket seals the intake manifold; it not only transports coolant to the engine but also oxygen. If the intake gasket develops a crack, the engine overheats due to leaking coolant, air, and gas. Keep in mind that the gasket is mostly made of rubber or plastic. Therefore it is prone to damage caused by extreme heat. Fortunately, although it can get cracked or damaged, it can easily be repaired if detected early.
If you own a diesel-powered vehicle, in addition to the reasons discussed above, white smoke from exhaust is usually caused by low cylinder compression, low fuel pressure to the fuel pump, damaged fuel lines, incorrect or broken fuel pump timing, broken injection timing, cracked or damaged rings or cylinder liners, and broken crankshaft keyway.
White smoke usually means coolant is getting into the combustion chambers of your vehicle. This generally happens because of a cracked or leaking head gasket, which allows coolant to seep into your cylinders. In extreme cases, you will need to replace your head gasket. At the first sign of white smoke you can try head gasket repair treatment to seal the leak before you do serious damage to your engine.
Water entering combustion spaces will also create white smoke. Faulty head gaskets and cracked cylinder heads or blocks are a common cause of water entry, and are often to blame. Unfortunately, expensive mechanical repair is the only proper solution here.
As for the leaking coolant, since you only have 1 indication of a blown head gasket, we would recommend do a few other checks for leaking coolant like a cracked radiator or bad radiator hose. Until you find the source of the leaks or have the chance to the mechanic look at the engine make sure to keep the oil and coolant topped up.
I have a bmw 328i e36 1996 model manual I was driving when I heard a boom sound coming out of engine. When I checked the radiator cracked. Bought a new radiator installed immediately. Today when driving temperature levels went up after it had a hard start so got to the garage put water about two watering cans still bubbles kept coming out. When I parked it white smoke was coming out of my exhaust system could it be my head gasket or leaking pipe. Please advise
Hello sir, my Honda accord v6 2003 model has been consuming coolant, I fill coolant with 10litres of coolant everyday. Now, I have changed the head gasket twice within a week, the coolant is still mixing with oil. And water is gushing out of the exhaust pipe when u rev the car. Could it be cracked block/cylinder? Can ur product solve this or I need engine replacement
turned on my 96 honda prelude. and left it at idle for 30 minutes, then went to drive it, but not after driving more than 200 feet i noticed the temp gauge starting to increase then white smoke and some liquid dripping out the tailpipe immediately after. I instantly pulled the car over nor more than 20 parking spaces down from the one I was at in my apartment complex and turned the vehicle off. the smoke then faded away and I went back to my apartment for a couple hours. after letting the vehicle cool down i checked the under the hood. I saw two things. 1 my coolant reservoir was bone dry and that a coolant hose leading from the engine to the bottom of the throttle body was weahter and had some dried green bubbles around the cracks. what do you think i can pinpoint as the problem?
Hi, I have a 2009 Suzuki Grand Vitara. The temp went to hot , I pulled over and had car towed to mechanic who told me the alloy head was warped , head gasket cracked and that i need a new engine at a cost of 8-9k. I suggested we could try head gasket sealer to which he agreed may work, Since getting car back the temp has fluctuated whilst driving short distances, when i pull over and rev the engine the temp guage comes down. I am checking the water level daily and have had to top it up. Is there anything else i can try or does it sound like i need a new engine? Thanks
A head gasket sealer must be applied by pouring it into the radiator. At this point, you can run the car for about 15 to 30 minutes with the heater and fan on high. The special chemicals in the gasket sealer work via the conduction of heat. The sealant will seek out and fit in cracks and gaps in the head gasket. Subsequently, they will harden to complete the repair.
What I Found Upon Pulling The Head On My 2010 PriusOne of my hybrid friends who had been down this road before gave me some excellent guidance once I was able to get the head pulled from the car.
I think that someone who can follow the OE procedures to do this repair can do it. I also believe that you are taking a considerable risk, only replacing the head gasket. My 2010 has 211,000 well-abused miles on it. I could instantly tell that the previous owners did not care about the car. The green coolant that had been run through the car was a big sign of that.
So, I think the question now is, Did I make a mistake buying a 2010 Toyota Prius? Time and miles will tell all, but for $500 and some of my time, I think for me, it was worth it. I learned a lot, even more than what I have shared with you here today.
The reason why coolant usually leaks is because there could be a crack in the cylinder head or even engine block. Even if the crack is small, the internal coolant can easily leak out and contaminate the oil of your engine. This is how the exhaust smoke ends up turning white.
I have a International 175 track loader. The outer exhaust manifold cracked and blew hot gasses on the trubo return line and turbo itself. The turbo is now dripping oil out. If the shaft runout and endplay is acceptable with no damage to the turbine wheel, can I buy a seal kit for it? Thank you
I have a 2010 focus 92000 miles on the clock. Regularly serviced. Its running a bit sluggish. Garage told me the turbo is leaking. They plugged her in to check reason why she is running sluggish nothing else found. How long will she run with a leaking turbo? How has this just happened n not been picked up before? Do you think I should get a second apinion. Regards Josie Barrett Mrs
Hey there i have mazdaspeed axela, had a smoking issue before and turbo and pcv system was upgraded never had a problem for 3000miles, then smoking occured again, although compression and leak down tests were done no actual faults were established until my brother noticed a crack in the rear housing of the turbo, about an inch long. We cleaned the oil thatd been leaking out this crack with brake cleaner and started it, it backfired alot so we knew the brake clean has made its way through. Any reason oil leaks through that exhaust housing crack? And is it safe to drive it to repair shop if i have sufficiant oil in the sump and no other problems? Thanks.
The quick answer? No! A blown head gasket is a major problem for any engine, and one that costs quite a bit to fix mechanically. The head gasket is responsible for creating a seal between your engine block (the lower portion that houses the cylinders) and the head (the upper portion that contains the valves). Your head gasket also acts to channel engine coolant to keep your engine cool during operation. A blown or cracked head gasket can cause one of two problems: 2ff7e9595c
