yea dieselgiant is a good guy.. i rember i ordered the valve adjust wrenches and he accidently sent me the vacuum arm things for the older om617 with the vac box on top ... i was like.. so i use these to remove the gasket?.. he told me to send them back and he sent a bottle of dieselpurge back with the correct order( i have yet to do a diesel purge.. or adjust the valves.. the 22 wrench on the ps bolt didnt work)
