You can drive it for as long as pie tastes good!
Every minute you drive a vehicle with a blown head gasket there is just that more severe internal engine damage. Drive it long enough and you will be buying a new engine or at the very least having this one completely rebuilt.
No. Driving the car with a blown head gasket will cause the motor to fail completely. Get the car towed to a mechanic as soon as possible.
Not very long as it is only an emergency repair. The only fix for a blown head gasket is to replace it.
Every time you start the engine you are doing damage. The coolant will mix with the oil and coolant is a horrible lubricant. How long you should drive it is none at all. Do not run this engine with a blown head gasket or you will be paying for a complete overhaul or buying another engine.
no. depending on how long the car was driven with a blown head gasket some serious metal on metal warping could have occured if are trying to buy a used car for cheap that had a blown head gasket i wouldn't recommend however if its your car that has the blown gasket take it to the shop very easy to fix
It is the head gasket is blown or crack
Once an engine has a blown gasket, it could die at any second. Driving such a car would be extremely dangerous as the engine could break down unexpectedly.
no as long as you are sure which side/head is leaking
At least 4 hours or more.
Depends on who performs the repair and if the heads need resurfacing or replacing. Also depends on how long you drove this car with a blown head gasket. There could be other damage.
The answer is Yes, The car will run and drive but here are a couple of examples of what is happening. Blown head gaskets allow anti-freeze coolant to flow into parts of the engine it shouldn't. If the coolant is going into the piston cylinders the car will smoke a lot. If it is going into an oil passage it will turn you oil into a milk like state. Lastly the bad gasket may just allow the anti-freeze to leak out of the engine onto the ground. In all cases the car will drive but not for long.
