Can anyone help why might my fiat 780 be making that kind of sound but when the exhaust is on I was driving her and all of a Sudden their was that noise and while bad she then died out I phoned a man and he said it could be a broken valve but I don’t know if it would be the same song any help appreciated thanks
YOU ARE LOOSING PRESSURE ON THE CYL. HEAD Really check your cylinder head bolt must be tightened with torque with 180lb/ft or you must tapping the tread in order to tight with oversized bolt to keep close the head without loosing pressure

Probably better pulling off the head I remember my 780 the valve broke on hit the piston I had to replace the piston an get the head fixed
