dcrow Posted June 29, 2017 Share Posted June 29, 2017 I'm getting ready to adjust the valves on my 07 ac350 and the manual say I need a special torque screw driver for the spring loaded exhaust valves. What is the torque for this so I don't have to buy a special 1 use only screwdriver? Is this the same on all e7 engines? I already have the motor turning tool.

Apply pressure to collapse the push tube spring and set drag according to what you would have historically. The tool is a dumby-proofer option. I leave the wrench on the adjuster nut and tip my elbow onto the wrench it while I set the clearance. Need very little pressure to neutralize spring pressure.
