Rocker Arm install troubles... Help
I had to pull the passengerside head off my 83 F250 6.9 this week because I broke a glowplug tip off in the head. So, I have the head back on the motor and I was bolting the rocker arms back on (going by the book, Chiltons) and when I started torqueing the last ones down I snapped the bolt and the piece that looks like this _n_ in half. How am I supposed to torque these down. Do I turn the motor so the valves should be closed at the rockers I am installing? Because when I was torqueing the bolts down that broke it was clearly trying to push the valves open before it broke. The book sucks.
Also... where can i find another piece that lookes like this _n_? It goes from one rocker to the other.
Thanks in advance,
Jerry in Nashville

The original 6.9 rockers are weak, and they wear out, and they break, guess you know about the last part.
A much better rocker in the 7.3 style, they bolt right in.
No need to roll the engine over as you install them, just run them down to torque, the roll the engine over and recheck the torque.
For what it is worth, Advance Auto has them listed as in stock, 12 dollars.
So it looks like you can replace them all for 96 dollars.

Does that fuel heater really do anything or would you suggest I get find one?
