Yes, if one of the tie rods have broken which secures the tank to the outer flue then the sealing 'O' ring will fail causing a loss of pressure which is creating the leak. When you strip the tank down make sure that all the other tie rods are in good condition because due to the fact one as one has failed then it may lead to another in the short term which is the task of doing the whole job again.
As a piece of advice, all the tie rods need to be tightened equally as the big 'O' ring sits in a small funnel like trumpet that seals against the flue so you may have to loosen each one of the tie rods and then tighten them up equally to maintain a perfect seal. The non return valve is a part that can often cause problems on this model and is much easier to replace when the tank is removed. For the sake of about 8 quid it may well be worth replacing it especially if you have had problems with back pressure at the water housing or problems with the water system pressurising.

My apologies for stating that there are 4 tie rods. I was thinking of a hydraulic or pneumatic cylinder which hold extreme pressure so has to have 4 tie rods on each corner. It's been about 8 years ago since I stripped a Carver Cascade water tank apart so it's been a while and can sometimes forget things. So, yes, you are right, there is only one tie rod in the centre but glad you bought this to my attention as the last thing I want to do is provide innaccurate information. At least one good thing is that you only have to replace the one single tie rod.
Sorry for for any misleading information.
