bent push rod
hi
ive got a 2001 f250 sd ps 7.3 td
have been having power problems for a while now, changed the cam sensor which did not solve the problem (that was the exact symptoms) so then swapped over one side of the wire harness, still didnt fix the problem, have taken the 2nd side of to swap the harness and found that i have a bent push rod and also a broken rocker arm bolt, now trying to source some of these from the states to australia to see if this solves my problem
does anyone know what would cause the push rod and bolt to break in the first place ??
thanks in advance

Sorry I missed your first post there Laser1.
To answer your question, I have found that the Powerstroke engine tends to loosen up the rocker arm pedastals over time and it is a good idea to remove the valve covers every 50,000 miles and retorqe everything. Even the injector hold down bolts.
I believe that is why your bolt broke off and bent the rocker arm, it was loose and rocking back and forth during engine operation.

excellent advice, so much so that this is my next to do. thanks. a loose bolt at the rocker arm and a bent push rod. i havent had the rocker shaft out of one of these yet but if you had that problem new bushings would need to be looked at. check the shaft play any way. that shaft is one of the things that can cost a lot of money if it grenades.

About a year ago I had the rocker covers off to retorque the injectors and I found nearly half of the rocker pedastal bolts were barely snug tight.
Setting the torque wrench to 20 foot pounds, about half of them took some more, the rest were still good.
EVERY injector was loose,
even though I had torqed them to spec, 120 inch pounds. I got nearly 1/4 turn out of every bolt. 
After I did that the engine really quieted down.

This just became my Saturday morning project.....I haven't touched the valve covers since I put the injectors in 52,000 miles ago.
Thanks for the Reminder Dan!!
