Eco-diesel Alert

This keeps getting more and more weird.

How do we get from a bad fuel pump to loose timing components and pistons smacking valves and broken rocker arms?

No hp fuel pressure tech assumes bad pump caused by bad fuel.  Finds some evidence  of fuel contamination replaces fuel pump and related components.  Still no fuel pressure. Finds pump drive gear spins free.  Assimes frozen pump had caused keyway to shear and - this is a stretch- cam gear to slip throwing cam outa timing and causing valves to hit pistons breaking rocker arms.  Usually catastrophic but this engine the design of such rocker arms “may” protect engine.  It does run fine for now. 

Why tech did’t check screen in pump to confirm debris ?  They must have tried to turn by hand and assummed seized but those dont turn by hand when full of fluid I dont believe.

So you discovered this or they discovered it? They still have the truck?

I don't mean to grind on you for answers...I'm just genuinely curious. This seems like a giant cluster. Not sure how a dealership could get this far in and not realize what's actually going on.

My discovery.  I took the pump apart found it in perfect condition.   Meeting with Service mgr this week to discuss refund without going to small claims court which he says won’t be necessary. 

Jackelope:  Your comments and suggestions motivated me to dig into this further and contact oregon fuel standards dept. Big help. Thk you!
