    Symptoms of a blown head gasket?

    My car is pretty much rooted, the auto sparky couldnt fix it in the two weeks it was there and the mechanic didnt have a clue either. It stalls at neutral, idles very roughly and i only get about 200 kms or less to a full tank (in an EF9). Someone suggested it may be a blown head gasket, does this sound right? If not what else could it be? I know its not the ecu coz we tried swapping it with an xsi's one. Its going into honda on the 6th as i have no other option. If any one has any idea of what it might be i would appreciate it heaps, particularly if its gonna save me a few dollars

    I am not sure on the full symptoms of a blown head gasket BUT I know if you have a blown head gasket the car will be low on power and will be using heaps of water.

    A good way to check is have the car at idle and open up the radiator cap if there is bubbles coming to the top or using lots of water its bad.

    Another check is if there is water in the oil (read dipstick) then the gasket is fucked...

    i agree that it soudns liek a fuel problem, but it would make more sense that it was good on gas if they were blocked, maybe ur O2 sensor??

    um using heaps of gas can be a blown head gasket as well, with out the large amounts of water coming out the exhaust, and using water.
    is there like a black soot on the back of the car?

    a blown head gasket wont by it self make u use heaps of gas, it could account for the rough running but there would be other visable signs as well, does it use coolant / water does it blow it out the radaitor cap, does the car fume excessivly white or steamish from the exhaust, does it have external oil / water leaks from around the head,
    a mechanic can tell u if the head gasket is blown realitivly easily with just a few simple tests

    for example a tee kay head check is sum thing u jam in the top of the radiator and if carbon monoxide is present the fluid in the tester changes colour
    they can also pressurise each cylindar thru the spark plug hole and see if there is any noticable leak


    as for the rough running / excessive fuel complaint
    a few things worth checking are

    -map sensor, this little bastard in my opinion would be the first place i'd start i'd obtain another one the same remove ur's make sure the hole aint blocked and try the new one making sure the oring is in ok nic.

    - idle screw, is clean not blocked located on top of throttlr body

    -o2 sensor

    -fuel pressure regulator, and fuel return line isnt kinked or blocked try blowing thru with compressed air

    -injector harness wiring no damaged wires or shorts,

    - exhaust restriction ( blocked cat or crushed exhaust )

    - intake restriction ( blocked air filter )

    - u could try changing the injectors but in my opinion its very un likely they are the root cause.

    K it turns out it was the water pump and the head gasket. I think the water pump coincidentally went after the head gasket so thats getting done at the moment, then i'll try get a mate to do the head gasket. Cracked my radiator the other week too, I'm just looking forward to the day when the car is actually running without any problems
