I had two that looked like that. . I think they were intakes... I didnt want to wait on new ones, so I took a die grinder with a fine sand paper style die and cleaned the inside and the rod up... I wonder what in the heck makes that happen and if anyone else has had this happen?? I will be trying to buy some used ones somewhere... .

It looks like you may have other issues, but here is some guidance on the orientation of the crossheads:

Upper Valve Train Assembly <?xml:namespace prefix = o ns = "urn:schemas-microsoft-comfficeffice" /><o></o>
Rocker shafts - installed with TEI-xxx toward the front of the engine.
Crossheads – Dot on top side / long slot toward the exhaust manifold.
Valve lash adjustment, each mechanic has a slightly different feel.
- Tried the M11<?xml:namespace prefix = st1 ns = "urn:schemas-microsoft-comffice:smarttags" /><st1:stockticker w:st="on">EGR</st1:stockticker> procedure with 6 in. /lb. torque on adjusting screw. Could not move the feeler gage.
- Lubrizol mechanic has an adjustable torque wrench, he try setting valves with it when he gets back to his lab. ( 1 to 15inlb. Adjustable wrench)
All valve train parts are pre lubed with Cummins Premium Blue oil as they are installed in the engine.


This information came from this website:

Some say the orientation doesn't matter, but they obviously were marked for a reason. Dunno...
