I'm in the same boat, pinlock no longer functions because I suspect the visor is warped (how I don't know). But on a 3.5 year old helmet I'd rather just get through this last winter and then get a new helmet before next year May vs getting a new visor which is 25-35% the cost of a whole new helmet
You can try some silicone spray on the gasket.
Obviously make sure the pinlock is fitted correctly as well.
