If the engine is run while the gasket is blown, the engine will overheat and eventually blow or seize up. If the gasket blew and engine was soon after turned off, there may be no further damage to the engine. Replacement of the gasket can get this engine in working condition.
If you drive with no antifreeze in your radiator you could ruin the motor. At a minimum you would probably blow a head gasket. The worse thing that can happen is that the motor will freeze up.
Short answer is yes.
water or coca cola
Along with the head gasket you often get warping of the head. Coolant will get mixed with the oil causing engine bearing and ring damage if the car was driven after the head gasket blew. If you continue to drive the car you will eventually ruin the engine.
Blown head gasket. That milky look is coolant mixed with the oil. STOP driving this vehicle until you have this repaired or you will ruin this engine.
Yep. Don't run it this way. This means that water is also in the oil and will ruin the engine. I found out the hard way.
NO NO NO you can i guess but it will ruin your engine. You either have a cracked block or blown head gasket i would guess. Moisture in the engine will destroy it. In addition to a headgasket or cracked block (unlikely), would be cracked cylinder head, intake manifold gasket or manifold. What kind of car, what size engine? 1999 CADILLAC DEVILLE
No the engine is not ruined. It needs a new head gasket and an oil change after the gasket been changed.
As I have no idea what you mean by "MOT fail" and I cannot answer except to say that a blown head asset is very serious and you should stop driving this vehicle immediately. It is a major repair but easily repaired with new gaskets unless you continued to drive the car and ruin the engine.
If you have coolant coming out of the exhaust. You have either a blown head gasket, a cracked head, or a cracked block. This can totally ruin your motor.
if it is just a blown exhaust manifold gasket it can ruin your valves, so replace it correctly and make sure everything is clean before putting on the new gasket
If you are loosing coolant with no apparent leaks, then you may have a blown head gasket. This is very serious and will in time ruin your engine. If you have white exhaust smoke with a sweet smell, that is a good sign of blown gasket. Also bubbles at the radiator with the cap off, is a sign. Have this looked at ASAP.
Neither. Have a new head gasket installed. That is assuming you did not completely ruin the engine by continuing to drive it after the head gasket blew. If you did indeed ruin this engine, then the decision should be based on what the car is worth in the first place.
why do you want to. This would be a terrible idea as the 2.2 engines have head gasket issues. When the gasket weakens, the engine will start to overheat, and without a thermostat you wont know until the gasket blows and you ruin the entire engine. So you "can" run without a thermostat if you feel like blowing your engine.
If it is an internal leak the coolant will end up in the crank case mixed with your oil and it will ruin the bearing/engine - if external leak then the engine will overheat when it runs low on coolant, and blow your head gasket
