2003 powerstroke push rods
 

Hello, I have looked around and have seen some questions similar to mine but didn't answer them fully so I thought I would go ahead and try on here. I have a 2003 6.0that I just bought, one bad injector and 3 cyl.with no compression. Took off the right side valve cover and have broken and bent push rods and rocker arms. Now I have a diesel mechanic who says he wants to take the head off to see what caused that but what I'm curious about is that it has arp head studs,so I'm thinking they did the was studs and the push rods didn't seat correctly.So I have two options, take it to the mechanic and pay a few grand to have it looked at and fixed, or try to squeak by with just putting new pushrods and rocker arms in it, the real concern is that what if I put them all back in and start it up and whatever caused it in the first place does it again. Tell me what you think about this, Thanks.

Most likely not installed right, I bought a motor complete for $500 because they just put new gaskets on it and then it still had a bad mis, turns out the push rods were not properly seated and were sitting on the top edge of the lifter causing the valve to hit the piston causing the rocker to break and bending the push rod, replaced them and it ran just fine.
when you put the push rods in you want to push down on them with your finger and you should fell it spring back a little, it is just a small movement but you can feel it.

Thanks for the info, could it have damaged the head gaskets tho??

not likely, it will bend the rod on the first stroke so it won't allow air into cylinder if that makes sense

im also hearing things about the valves being bent from the piston comming up and hitting it and making a mark in the piston

If you look at the bottom of a 6.0 head you will see that the valve is straight down, meaning it will hit the piston flush, not like a regular gasser where the valves are on an angle to the piston therefore the force on the valve is on an angle causing it to bend, if you look at the 6.0 rockers they are not that stout and I believe they will break long before you bend a valve.

So u u think I Gould have the heads pulled or try to put new rockers and push rods in it and try it , I'm 16 years old and bought it broken pretty cheap and I'm right money but I also don't want it half assed

I would put a rocker on it and try it, easy to do and it will save a lot of money. this can be done in an afternoon with no special tools so it is definitely worth a try.

Thanks you very much for your information it was very helpful!! I'm trying to explain this to my dad!!
