2006 Huracan 5.0. Sometimes when it turns around it creates white smoke for about 30 seconds, mostly on cooler days. Mechanic where the car was taken to says it's the valve seals. Is that right? What's your opinion?

White Smoke in your exhaust indicates that coolant and or water is being vaporized in the combustion chamber and could mean the head gasket is leaking, the vehicle has a cracked block or cylinder or the engine is cold.
The spark plugs are just igniting what ever is in the combustion chamber. White smoke is probably steam from water. If the coolant is leaking into the cylinders from head gasket or a crack in the head or block, the exhaust could smoke white.
Can faulty spark plugs make your car blow white smoke out of the exhaust? Yes, they can.. Craig Nicol has it right.. Unburned fuel entering the exhaust can light off in the catalytic converter resulting in white, extremely acrid smoke..
White Exhaust Smoke
White smoke billowing out of your exhaust means that coolant is likely leaking into the cylinders. This usually happens when there has been a breach in the head gasket, which makes the coolant create this white steam.
This is usually brought on by low fuel octane, oil contamination in the air/fuel charge, or excessive boost or nitrous injection in high-performance engines. It can also be caused by poorly performed repairs, a clogged injector, clogged fuel filter, or a marginally failing fuel pump.
White or Gray Smoke from Exhaust – Just like if you see white smoke from under the hood, persistent white smoke usually indicates a coolant leak. If there`s only a little bit, it`s probably condensation. Blue Smoke from Exhaust – If you see blue or dark gray smoke, that`s an indication of burning oil.
White smoke is a result of unburned fuel particles passing through your car`s combustion chamber and out of the exhaust pipe. As previously mentioned, white smoke is related to lower temperatures in the combustion chamber.
Cylinder heads sit on top of the engine block to form the combustion chamber. The parts can become warped through overheating and cause your engine to misfire. When the air-tight seal is lost, coolant can slip through openings and burn as white smoke.
Black exhaust smoke “When your exhaust pipe gives off black smoke, one of the things to get worried about are bad or worn out spark plugs. It means fuel burning in the combustion chamber is not being done 100 percent or burnt fully. It also means that air is not being well mixed with fuel to burn effectively.
White fumes come out of the engine when engine oil leaks. A cracked gasket cover is one of the prime reasons for oil leakage leading to the production of white smoke. It`s super easy to replace a faulty valve cover gasket in the early stage.
If a valve seal has lost its grip or piston rings get worn, they can cause oil to leak into the combustion chamber. This wayward fuel then mixes with other engine elements and burns, causing white or blue smoke to escape from the exhaust manifold.
The symptoms of too much car oil
If it is overfilled, the following may occur: Dense white smoke – If you drive your car and see plenty of thick, white exhaust smoke, excess oil may be burning within the engine block, although fluids such as antifreeze may also be the culprit.
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.
Thick white smoke coming out of the exhaust typically indicates a blown head gasket, a crack in the head, or a crack in the engine block. Cracks and bad gaskets allow the fluid to travel to places it shouldn`t be. If it travels, then the problems begin.
White smoke from the exhaust: This could be steam caused by condensation in the exhaust pipe or a more serious issue caused by an engine coolant leak. Excessive amounts of white smoke could indicate head gasket failure. Blue smoke from the exhaust: Oil is being burned.
When the oil leaks into the combustion chamber, it mixes with the fuel and air being ignited and gets blown out of the tailpipe along with them. The result is white or bluish-white smoke. This is a problem because oil does not belong in the combustion chamber.
The most common answer to, “Why is my car smoking but not overheating?” is that there`s a type of fluid that`s landed on the engine. This can be motor oil, fuel, transmission fluid, coolant, or even condensation. It can cause your engine to smoke because it`s burning off that fluid from the engine.
If a bad oxygen sensor disrupts the air to fuel ratio mixture, or too much fuel is injected into the engine, your vehicle`s gas mileage will be reduced. This excess fuel in the engine can produce a sulfuric, rotten egg smell, and may even produce black smoke from the exhaust.
Many factors can cause a spark plug to fail; from incorrect heat ranges to improper gapping, to chemical contamination. Yet 90% of spark plug damage claims are due to improper torque. Many factors can cause a spark plug to fail; from incorrect heat ranges to improper gapping, to chemical contamination.
Repeated overheating of the spark plug tip can cause the plug to prematurely fail. Overheating can be caused by many things like pre-ignition and a malfunctioning cooling system. Pre-ignition can lead to heat building up in the combustion chamber causing the spark plugs to fail.
It is considered normal when the exhaust coming from your vehicle is light or thin white. This type of smoke is usually just water vapor. You will notice it when you first start your vehicle, especially on cold days. The reason for this form of exhaust is that condensation collects naturally in the exhaust system.
White Smoke
It could be overheating, and if it is, you need to stop driving as soon as you can. You could end up seriously damaging your vehicle if you choose to just ignore it. If the smoke smells sweet, then there is an issue with your coolant.
If the seal is faulty, you may once again see blue-tinted smoke when the engine begins to run. That means the oil is getting pulled past the seal and into the valve guide.
