Bent pushrod
 
Got a new 2500 and it bent number 1 exhaust pushrod. No obvious signs as to why although the tip of the rocker that sits against the bridge is broken off. Truck has 4000 miles on it.

New as in 2018 6.7 ? Did you over rev it?

It’s a 2017, I don’t know if it was over revved, I’m just working on it and trying to get a direction to go with it.

Probably nipped the piston too

Pull the injector and get a camera in the bore.

Injector was removed to see if there was any damage to it but will get a look with a camera next and post up what I find. Oh and do a leak down test to see if any bent valves. Thanks for the replies so far.

No warranty?

Must be modded, own warranty station......:rules:

Actually it is warranty and I’m the guy working on it at the dealer. Never seen this before so I thought I’d ask around to try and get some insight. Lots of knowledgeable people on here that may have come across this before. Appreciate the help. At this time we’re putting it back together to see what it’s going to do. I still have to do a leak down on it while the injector is out.

Take pictures of the fractured parts and post.

I don’t know how to post pics

Update in case anyone was wondering, did a leak down and was ok, put a boroscope down the injector hole and the piston was fine so I put it back together with new parts and it drives fine. Also of note, it’s a manual transmission so maybe the owner over revved it on a downshift. He didn’t say.

Yea I found the piece of the push rod that broke sitting on top of the cylinder head. Runs like a top, I really can’t explain what happened. I don’t know if I can see a peak rpm with a scan tool.
