Thank You Ryan,
I appreciate your response, however you mention a very minute split in either of the hoses could be the problems.
This may be so , but how would one find this minute split if at all, as a large amount of pressure is needed for it to fail, or could this be found by general thorough inspection.
I will lift the bonnet tomorrow and see what maybe hiding under there, thank you again, at least you have given an answer to my question which Holden cannot do.
