One man drove his car for 2 weeks with a broken head gasket before he blew his engine. Another drove it for 3 weeks. A head gasket costs several dollars if you can change it yourself. A new engine over a thousand. One mechanic can change a head gasket in an hour for $ 100. Other mechanics are no where near as good and take longer. It may be more in your area. How long do you want to go and how much do you want to pay?
You can drive it for as long as pie tastes good!
you dont, you will kill the engin!
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 long, combustion gases (hot) generally enter the cooling system and cause the engine to overheat.
Not very long as it is only an emergency repair. The only fix for a blown head gasket is to replace it.
Until the engine self destructs and locks up. You do not drive a car with a leaking head gasket unless you want to destroy the engine. STOP running this engine until it can be repaired.
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.
Long term, nothing short of a new gasket. Short term, in an emergency, something like JB Weld might do it, but would probably increase the cost of repair later.
not long If you are saying that you only have 50 psi compression on two of the cylinders, then you need to find out why those two cylinders are that low on compression. You may have burnt valves, broken rings, or a blown head gasket. A blown head gasket is very serious and should be repaired ASAP. Stop driving the car until you find out why the compression is low.
Never use sealant for a head gasket! It is used as a quick fix for cracks in the gasket but will not last very long. Safer to get the job done correctly.
As soon as water in seen in the oil reservoir it needs to be taken to a mechanic immediately. Further driving will cause the head gasket to blow.
