Help Please- Whilst working along the road at crawling speed, frequently stopping. my Temp light would illuminate and switch off when i moved a bit quicker. I checked the coolant level and it was low but the over flow was full to the top. Note- Radiator was cool to touch but both coolant lines at the engine were to hot to touch. evenetually whilst driving to get back to my location, the temp light came on then the engine and ESP light came. I pulled up engine still running i noticed huge amount of smoke coming from the engine area, after a further look i found the plastic cap of the crank case had blown off and smoke blowing out of the hole. Im convinced i have blown my motor any help would be appreciated
