The rockers on my one of my trucks are still the factory rockers it was built with, they have been on 3 different engines and have 309K miles

 

What springs did you use with that cam?

 

Sucks to see the carnage...Like I said in our PMs, just let me know what I can do to help!

Things break for a reason......so that you can replace them with better stuff!

 

They were pac somethings, can't remember the numbers right now



Yup, just trying to convince the wife is another story.LOL

 

Haha. I understand. For sure looks like a rocker arm failure. Let's be sure and do a Comp trunion upgrade kit while we are in there.

Let me know what it looks like when you pull the head off. I bet that valve is done for. We can replace broken parts and do some upgrades pretty cheap if you need to get it running ASAP.

 

I've never seen a spring come apart like that and not have the spring be the main culprit in the breakage...

 

Looks like rocker came apart, moved over slightly, compressed on retainer, destroyed spring. You can see the cups for the rocker trunion and needle bearings. I could be wrong, but I'm leaning towards rocker failure.

 

Yeah valve is on top of piston. I think it was rocker then spring. Kinda sucks but neat to see.

 

do u have the head off yet? how's the piston look?

 

No not yet. Will be monday or so.
