My fiat brava has recently had a leak in the radiator ,i can smell petrol or oil fumes when i top up the water in the radiator ,the engine is consuming more petrol than it should be and the exhaust is blowing .
someone told me that the head gasket is gone too ,how much would i expect to pay to have remedial work done
otherwise the car runs perfect

If the head gasket is starting to go, the the water gets vapourized inside the engine. The water level will go down, sometimes you get white smoke from the exhaust, the car consumes more fuel and has less compression and performances.
If you are lucky, and you check the water you can drive a car with bad head gasket for many miles, before it blows completely and leave you on the middle of a motorway.
If the head gasket is starting to go better to fix it or to replace the car.
The part costs only thirty pounds or so here in UK, but the job is expensive, as you need to take apart the head. Here in UK you dont pay less than four hundreds pounds, probably a bit more, depending on the garage.

Smoke (blue or black) or steam (white)? White smoke is really steam that is caused by water leaking onto hot surface. Could be leaking from hose running to heater coil under dash, or something else. Check radiator water level to make sure water level is ok. Blue smoke is oil burning. This could be dangerous, caused by similar scenario of oil leaking on a hot surface (from a gasket leak, etc), or exhaust fumes. Black smoke means something is actually burning and could indicate fire. Black or blue some could fill vehicle cabin with toxic fumes, even if you don't smell anything bad.
pressure test radiator by colour check system ,or check for petrol vapour in header tank or radiator, check oil in engine to see if it is contaminated with water oil ,could be leaking rocker cover gasket causeing plugs to missfire if gas, petrol smell from water its head gasket ,water in oil headgasket, oil in water headgaskget if any of these requires head skim and head pressure test by a engineer
if loosing coolant but no leaks anywhere inside or outside of car, and if it overheats due to lost coolant, we can say that your cylinder head has a micro crack on it. and coolant is vaporized inside chamber. you need to weld (or replace) cylinder head after removing it.
if its a petrol smell then maun suspect is head gasket leaking between a water port and a oil return gallery with the help of a piston hence the petrol as well ,without a complete strip down its impossible to say its between one and two or three and four cylinders or whatever if it was just water in the oil then its highly feasable its a radiator where the oil cooler is in the rad .But this smells of petrol so go the whole hog and pull the heads off
<grin> I don't know why or how this ended up under the category of Fiat 2006 X1/9 - I'd like to have one but I think I will have to be satisfied with my '87 Bertone instead-
I would highly recommend you have a shop replace the sensor (very soon!) with a pressure gauge to measure the pressure directly to make certain you aren't dealing with a failed or obstructed oil pump.
This will only take a few minutes and shouldn't cost much.
If your engine isn't clattering, I suspect the replacement sensor isn't any good either.
check oil colour(milky indicates water)check radiator,can you smell fumes in there,get it tested with and exhaust gas annaliser,which picks up engine fumes in the radiator if you cant tell for sure,it does sound like you have a head gasket problem,you would need to do both heads not 1
