You will ever find it without the boiler model although I think you mean the oe pushed snugly up against the gas valve don't you?

If its a SIT845 then its more likely to be a sticking gas valve statistically!

However that needs a competent CORGI to diagnose and change.

Anyway the OP is sure he knows whats wrong and certainly doesn't want to pay a CORGI for anything.
