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.
Not very long as it is only an emergency repair. The only fix for a blown head gasket is to replace it.
you dont, you will kill the engin!
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
You can drive it for as long as pie tastes good!
If the head(s) were checked and had no cracks and the coolant never mixed with the motor oil it could last for many miles depending on how many miles allready on the engine.
Nothing. There is nothing you can add to the coolant that will repair a blown head gasket or cracked head. There are products you can use in an emergency to possibly get you home but these are just temporary fixes that will not last long. The only permanent fix is to open the engine up, replace the head gasket or head if necessary. STOP driving your Toyota immediately or you will have severe permanent engine damage.
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.
Normally it will last the life of the engine. However if the engine overheats the gasket can be ruined immediately.
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
