The best quick fix is to replace it as there is no quick fix. There are products that can be poured into the engine that claim to fix bad head gaskets. That's more of a "let's see if we can make this even more expensive" fix.

Why is head gasket in your car engine always cracking?
Like any seal or gasket, when you have a tramendious amount of presure that is constantly trying to escape, over time that seal or gasket, locking in the presure, will get old and start to allow leaks. This is from the constant fluctuation in temperature. Once a small leak occurs it will only get worse until you replace it

Can you put rtv in valve cover?
It is not recommended to put RTV INSIDE the valve cover. If it were to turn loose and fall in a place that may cause a valve to not open correctly which could lead to damage to the valve or rocker arm. It is OK to use as a gasket sealer and the little bit that may squeeze through to the inside should not hurt anything. Do not try to use it as a patch though.
Why is white smoke coming out your tail pipes and you need oil often?
Did you accidently add any motor oil or any type of oil in the fuel tank? Does the car produce this white smoke at normal operating temperatures? If it does, you should seek a professional opinion. If not, this is normal. Your piston rings could also be shot. Causing oil to get into the combustion chamber and burning. AND NO OIL DOES NOT BURN BLACK(DIESEL DOES) IT BURNS WHITE
AnswerIf you are having a lot of white smoke all the time the car runs then check for coolant mixing in with the oil,look for water in the oil when you check the oil or milky brown oil. This produces a white "steam" that is very thick to come out of the exhaust. If your engine temp. gauge is very high and over heats you probably have a blown head gasket. If it has a bluish tint look it may be burning oil. Indications might be how much oil is currently in the car i.e too much oil, or if there is a leak in the line you may be adding a bunch of oil over a short time. If it is only when you first start the car and the engine is cold, then it may be that your valve seals are bad and need replacing. Hope this might help or at least give you some ideas... AnswerIt's coolant. headgasket, cracked or warped head, intake manifold or gasket, or cracked block are your sources. Take it to a care car service to have it checked Answerare you sure the smoke is white or is it a light blueish color start the car and have someone stand in a position to see the tail pipe and see if much water comes out with the smoke if it does and you have been running low on antifreeze i would say a head gasket if no water and not low on anti freeze look at worn valves or valve seals or worn rings good bet on these two items good luck AnswerBurning oil in the fuel would cause black smoke so it definitely has nothing to do with that. White smoke can be caused by water in the combustion camber or unburned fuel. If you've be having bad gas mileage you probably have a problem with your fuel or ignition system or timing. You can usually smell the fuel in your exaust when this happens. If you smell no fuel and you've had no change in fuel economy check for water like one of the previous posts said. AnswerTry the changing PCV, it work for me when white smoke(rock concert-like) would come out of the exhaust everytime the car was turned on. That was the only time the white smoke would come out in my case. If it is a constant white smoke emitted from the exhaust, especially while driving, it could be something else. AnswerOne thing that I noticed, is that when valve seals get some years on them, a little bit of white smoke can emitted from the tail pipe when you first start it up or when you set at a stop light idling. But usually not that much smoke. Old valves could be causing you to run rich. AnswerSomehow water has or is being burned,check coolant level and temp if you have temp light put a guage in if coolant low there is your problem if not check egr valve and pcv valve also check oil level if high and milky there is high possibility that you have blown head gasket and or block may be cracked allowing oil to get into the oil pan. Answeryour rings. Answeri think it would be a blown head gasket or blown headCan a head gasket leak without overheating or coolant loss?
It is possible that the gasket could leak between cylinders. The overheating and coolant loss would happen if the gasket was failing around the coolant passages.
Does a blown head gasket affect the heater from getting hot?
When a head gasket blows, it most often causes a lose of coolant either in the exhaust or the oil. When the coolant drops, there is not enough to circulate through the heater core. The engine may over heat but no heat will come out of the heater because there is no coolant in it.
