My 211 Sprinter is building up pressure in the water header tank and water is coming out of the overflow valve(I think thats what its called). I was just told that I might need a cylinder head gasket. Has any one had similar problems?

It does sound like head gasket. It best to get it checked properly

Is the running temp ok?

It could be a head gasket or a failed water pump.

If the system is being highly pressurised when cold then go for head gasket.
