Truck Repair: L10-350E engine valves and injectors adjustment, screw out, rivot


Question
Hi Cliff, i am having a problem with the L10-350E engine valve and injector adjustments,what is the proper tune-up procedure for this engine? is L10-350E and M11-350E engines are the same when it comes to valve and injector adjustments?

Answer
If they are both electronic they adjust the same way. The adjustment for a electronic engine is  A= 1 & 6 B= 5 & 2 C= 3 & 4.You adjust valves & injectors on the same cylinder.The valve specs are Int 0.014  Ex 0.027 The injector adjustment is 1)Loosen locknut.2)Bottom injector plunger in cup by turning screw clockwise BY HAND ONLY until it just stops.3)Back screw out 2 flats(I use the corners of the screw and the rivot for reference..ie line up a corner of the locknt with rivot & back it out 2 corners).4)Adjust valves on that cyl.
