Is the VE made with hydraulic valves like the DE that don't require any adjustment or are they something else? If they are the other type (whatever you call those) do they adjust just like my Datsun L16 engine with a feeler gauge and all? Does anyone know the clearance. I am trying to help a fellow VE owner who says his need to be adjusted and doesn't know the clearance. I was pretty sure the VE was maintence free as far as the valves goes but I'm not 100% sure.
