Corsa 1.2 Cam bolts

You have advised changing cam retaining bolts on current Corsa 1.2 petrol models. What should be done if the dealer refutes the necessity? Does this have to be done at each annual service or only the once?

The stretch bolts eventually stretch and cannot be re-tightened so need to be replaced. get the dealer to guarantee in writing that this will never be necessary and that your engine will never fail for this reason.
