    Far rear lower bolt on the cam follower was finger tight. I was afraid it was stripped but it doesn't seem to be. Problem is in 3 large boxes of tools I couldn't find a combination of ratchets, swivels, ball swivel sockets, wrenches of every shape and size and twist and turn that would get on that darn bolt and tighten it.
    Alas, the darn starter has to come off. :biggrin_2553:
    You can bet your last nickel that thing will have lock-tight on it when it goes back in. :yes2557:

    I didn't know all of this before I pulled mine off, then I went to talk to the mechanic, he told me it was no big deal. I went to the cummins dealer got the Jake Brake gasket, and I got the Followers cover gasket to size.

    Before you take off the cover behind the starter, you have to take the valve cover off. Then take off the ''Jake Brake'' there are 6 12 point 7/16 bolts that hold it. Then you take off the Rockers 4 12 point 9/16 holding those. Then you pull up the rods and tie them up so they don't fall and break, or if you have room to take them out, do so, but make sure they go back in the same order so you won't have to re-adjust the valve lash.

    Then once you got that going proceed to take off the cover behind the starter. Clean everything up, put a new gasket on it, and reassemble everything.
    Make sure you get the followers go on the shaft when you put the cover back, not below it, and the rods up at the top go back in place in the designated for them spot in the cover its self. If you are interested I have pictures of what everything looks like, you can email me. and I'll send those out.:biggrin_25520::biggrin_25525:

    Hahaha... where were you a week ago sergey:biggrin_25510:LOL.:biggrin_25525:. I hired a guy to help me with it. he came from about 150 miles out and charged $400. I know now how everything works and feel the cost of education was worth it the first time I have a jake problem or need to run the overhead... Thanks for the info though. I appreciate it very much.

    Well I ran into this problem then started looking online for answers on how to fix this problem.
    Because every mechanic I called was busy or couldn't come out of his shop to fix it.
    Thats how I found this forum. Once I figured it out, while fixing it I made pictures in the process, then decided I could help someone else.
    And the cheapest I found was $350 to fix it.:biggrin_25519:

    Help! Mine are leaking at the front cover, behind the air compressor (air system not AC) I got and estimate and shop wanted a pretty coin :biggrin_25524:. With freight this slow, I'd rather do it myself and save a few bucks. :D

    I've replaced an injector in my N14 once, so I do have some skills. Just a little worried about the cam followers.

    I don't have enough posts to send PM. can you PM me some pics. Thanks. :biggrin_25514:

    You might wanna try to tighten the bolts first, cause that front cover has something to do with ignition and even I wouldn't mess with it unless I've seen it done before, and as far as the pics go my computer crashed so I lost everything. I use my cellphone for accessing the net

    Yep. I tightened them and some were a bit loose. I'm afraid though, that the gasket may have broke thru so it will continue to leak.

    usually the gaskets are intact....the problem is cummins torque spec is only 35 ft lbs on those bolts. then if you have to shim the followers, it doesn't create a real good seal :/

    to reseal all cam followers it may cost up to 2k in labor....it is a time consuming job.

    I was wondering if that would work. Still have to pull the compressor but nothing up top. How far out can you wiggle the cam follower cover with the pushrods still in?
