Long story short, truck hasn't been ran in 3 months. Changed head gasket before It was started, took it on a test run and about 1/2 mi from home #6 intake rocker plastic retainer had enough.

I'm guessing it broke, then pushrods shoved it up pushing the bridge off the valves. When the rod came up it also pushed the rocker far enough over to lodge it into the bolt which didn't allow it to rock anymore. 

 

Got home and found a few others where cracked/brittle so I ordered new ones. Turns out cummins has a newer updated style, ordered them on Saturday. I'll let y'all know how then are when they get here. 

 

Pics of #6, and stock photo of the new style. Part no. is 4995602

 

 

What.... and this whole time I thought it was all metal, great..... Thanks for pointing that out. I didn't even pay attention to mine, maybe because they were in one piece and I didn't realize there was plastic involved. I'm loving this more and more.

Same, I never paid any mind to it. I looked more into the faces of the wearable areas when it was all apart. 

Well boys and girls the new rockers came in, ordered them knowing I might be getting an off brand but took the gamble and it paid off. Managed to get genuine cummins, but sadly from India. 

They were cheapest I could find the part number, they are from M&D distributors, free shipping too.

 

now I get to battle a bad injector issue. 

I've got to ask what was the total cost of the new rocker arms for the set?

True, but I don't care enough to find out. I'm sure they'll be fine, they came in the high class box anyways!
