Report "I have a Tata indica 1400. Head gasket blew and I ran the engine for a while still about 40km. Back home I replaced head gasket as head and block seemed okay. Car starts easy but there is something very odd happening. When we filled up with water to check leaks and if the cooling system works. All went well. But when replacing the expansion bottle cap the engine slowly stalls ?? Yes. It stalls. How is this possible ?"
