    ok, got heads torqued down. Injectors in. Glow plugs out. Tried to turn crank with wrench. Turned for a little bit and stoped. Reversed it and it stopped. Noticed that #2 ( drivers side towards front of truck ). piston did a complete up and down but didn’t rotate all the way to the top.
    What could cause this?
    What other piston is up at the same time so I can check it?( got a camera I can look in with the injector out, just didn’t want to take all the injectors out)
    All the push rods and rocker arms look ok from what I can tell
    Only took heads off. Did no work on lower end of motor

    I would be looking to see if something was left in a cylinder.

    I finally found out that 2 and 5 reach top at the same time. That’s where it stops. So I started looking at 5 really hard. Noticed that both rocker arms were tight at the same time. Took the rocker arm off and it made a complete turn. Nothing wrong with the push rods. Trying to see better in the cylinder. Could I have thrown off the timing somehow?

    Make sure the timing makes line up on the cam and crankcase. That is how engines are timed. Then be careful in setting the rockers. Check them frequently as you assemble the rockers and push rods. Spin it over after you add the injectors and glow plugs.

    Ok. Found it. #5 push rod was not in the hole correctly. Bent it a little. Going to replace and continue on.
