I have 2006 Volvo D9 500HPs. User manual shows at 1000 hrs that the 24 rocker arms / valve adjustments is required. I think the lifters in all D series are hydraulic like car engines. As hydraulic lifters self adjust to take up any slack, why is this adjustment required ? The solon floor in my Carver Voyager 46 is too close to the valve train cover and it can't be removed without cutting huge holes in the solon floor plus cutting several aluminum floor supports. This would be a very big undertaking.
