Is there an effective, simple, temporary repair for a head gasket?
Sloshing sound??? You can tell if your head gasket has ‘gone’ by taking off the oil cap and examining the inside of it. If it has gone it will be a mixture of oil and water and be a slushy light browny type coating it. If it is pure black then it is likely it isn’t your head gasket. When the head gasket blows it nearly always blows water through into the oil. It rarely blows oil into the water unless it has seriously ‘gone’. The water in your radiator system will keep losing water so that is another sign. Check the dipstick. It will have a sludgy lightish brown watery substance coating it rather than nice pure oil…. The result in driving your car like this is that your engine will seize and your car will probably need a replacement engine… It will probably write it off too if it is an older type car… £200 sounds quite cheap so If I were you I would fork out for it now but get a few quotes first if you can…. Good luck..
