hi guys does anyone know what's up with my vr6
had a top end rebuild after xmas cos the head gasket went, only done 92k
new timing chains and pulleys also fitted
but sadly its still losing water, soo my garage checked it again no leaks on any pipes, they checked the gasses in the expantion tank and hey its the same prob soo they removed the head and pressure tested it again that is fine
soo is it my block what might be cracked or could it be something else
thanks guys
