Hello, good forums. I bought a 306 griffe a month ago and when I bought it, there seemed to be no problem, but a week later, the gasket exploded without heat, my master said it was caused by the tube brain. Anyway, the top cover was stoned, the valves were stoned and the gasket was originally installed, and the fabricated gasket came out from the top, the cap never opened before said my master. After that, a metal sound started to come from the engine of the car and the temperature does not go down from 100 even at idle yesterday, I entered a congested traffic and it rose to 110 quickly, I pulled aside and waited for it to fall, I tried to see if the water was turned on and reduced, as soon as I turned the lid, it started throwing water from the edge and I closed it without opening. I know that this is normal or there is a remedy for these cars, I know the valve adjustments need to be made again, because of the low speed gas cut-off and the metal sound in the engine, but the heat, I do not know what to do, by the way, I use the car in gasoline because I do not have time to make the tube brain.
