the head could be warped BUT try removing the thermostat because that could be a bad thermostat try running it without it if its a blown head will not have compression and the oil will look milky
Could be a head gasket or a warped or cracked Cylinder head.
The head will have to be pulled and the gasket replaced. If the car overheated the head may have warped and will need to be resurfaced or replaced as well.
No, the only permanent repair for a blown head gasket is to replace the gasket. Anything else is just an emergency repair.
if my heads are warped and gasket needs replacing what longterm damages and repairs should i expect
is it just residue from where the gasket is gone?, if not there is a possibility that the head is cracked, was the head checked to make sure it was not warped? and pressure tested?, also you might have an additional problem, radiator blockage,thermostat stuck or if its the k series the dreaded ballbearing problem, each of these could cause the gasket to go again
Could be many things like a stuck thermostat, blown head gasket, warped heads, bad water pump etc.
The thermostat could be installed backward, the radiator could be plugged, the water pump could be worn out or you could have a warped head and bad head gasket.
Have a compression test run to see if you have a problem with the head or gasket. Once you find out you do, then you must remove the heads in order to determine what the problem is. Have the heads inspected at a machine shop to determine if they are warped or cracked. Once the heads are removed the gasket must be replaced so it really makes no difference.
There's only one way to repair a blown head gasket and that is to replace the gasket. You must also check to make sure that the head is not cracked or warped If it is the head will either have to be replaced or machined depending on the severity of the damage.
The intake manifold and exhaust manifold must be removed. Then the head must be removed and the gasket replaced. The head must be checked for cracks and to see if it is warped. Then it is all put back together.
A faulty thermostat in a 2001 BMW 325CI can cause a coolant leak. The coolant may be leaking out a crack in the thermostat or through a warped edge. In some cases the problem may be just a bad gasket and not actually a problem with the thermostat at all.
if you are losing your antifreeze its probably a head gasket or the heads are warped if not its probably the heater core
