Bent Pushrod - Replace Follower? Also Cracked Pushrods
'05 F350 6.0L - So apparently in my hast to put everything back together after the ARP studs, injectors and Oil Cooler intstall, I did something wrong and have ended up with a bent pushrod.
Also while I was extracting the pushrods, I noticed that a couple of others seem to have cracks - one that goes almost completely around the pushrod and the other about half way around. both cracks are a little bit below half way down the pushrod, one on the same cylinder as the bent pushrod #4, the other on #2 Cyliinder.
So 2 questions:
When I insert the other pushrods into the slots it feels almost as though there is a seat that they fit in to, but when I insert the new pushrod into the slot that had the bent pushrod, I do not get that feeling - should I replace the valve tappet?
Question 2 - I am replacing all of the pushrods on this head regardless, but are these cracks normal? and should I replace the pushrods on the other head?

Reason: Bad wording
I double and triple checked and checked again when i put my pushrods back in. There were a couple that had a hard time finding the right slot to go back in probaby because of the angles. Just take your time and make sure you get it in the the right place. Not sure about the cracks, but that doesn't sound normal to me.
Thanks worldwide73. I took my lighted magnet and stuck my head down there to see if I could see anything and it looked like there was something in the way. I was actually able to get the pushrod to go down at an angle and then move it to the left with a slight resistance and feel it seat like the others, so I am thinking that there is something in the way.
I am going to pull the head off - I think it is the best course at this point and a lot less work to pull the rest back off than if I put it all back together and then something is still wrong.
Will check back in when I get it apart. Ordered another head gasket
Yea - I wish I had cheezit's knowledge and experience. I've read a lot of his stuff and tried to abid by his suggestions. It's just hard to justify the tools to my wife after spending close to $5K for parts when there wasn't anything wrong with the truck to begin with. She doesn't care how much time I spend on it, just dont dip into her spa money!!!
So head is off - Head gasket is ripped and bent around where the push tube goes through it - that is probably what I saw. Also the plastic fins at the bottom just above the lifter - they look like they collect and focus the oil back into the hydraulic lifters - the right side of the one where the push tube was bent is torn. I will take pictures and see if I can get those out later this evening - My wife has a web site - maybe she can put them out there and I can use her URL to point to them.
