Hey guys,

This Sunday afternoon I figured it would be a great time for some general tune-up on Betsie.

I planned on doing valve adjustment, diesel purge, fuel filter change and oil change.

So, started with the valve adjustment. I'm following this pictorial:
Mercedes Diesel Valve Adjustment Procedure

Got the valve cover off, and I have the first cam lobe pointing straight up. Is this correct? The pictorial talks about it pointing straight up, but also that it will look like it's in the 1 o'clock position. I have it pointed straight up. Should I turn it a little further so it is just a little over straight up?


Second question:
I made two 14mm wrenches with a bend in it to reach the adjusting nuts. I put one on the upper and one on the lower and try to loosen the lower by pushing counter clockwise on the lower, while holding the upper still.

However, I can't get the frikkin' thing to budge. How tight are these nuts? I've never done a valve adjustment before, but I put the work on hold for now until someone get maybe give me some tips or advise on the cam lobe position and on how tight the lock nut is supposed to be?
