This is not your old ford that we are talking about, Its a cummins... . its built to take it!!!! Mod away, and just keep an eye on that serp belt!

And get some real exhaust on that thing Scott

Wow! Tough crowd! :-laf



Kevin, actually, this truck runs like a dream. Smooth as silk, and very powerful. And believe me, I DO keep an eye on that belt. I check it weekly.



Mike, I DO want to do the exhaust. Just not sure what.

Compared to my first or even my second CTD, this one has plenty of power stock although I would like to take a ride in one pushing the 500 hp envelope just to see what that feels like.



The guy who's engine blew up, what did he do with the truck? Did he tow a trailer frequently? Did he have an EGT gauge? It sounds like the guy knew how to work on it and understood how a diesel works since when it started running rough the first thing he did was the fuel and air filter...



It's always a little unnerving when a truck identical to your blows up without knowing it blew up because the guy abused it. He was just driving it...

I wonder if the dealer did an oil change? With a hole in the pistons there should be a good amount of fuel oil dilution. I would check it out especially when they left everything under the hood a mess. Same $$$ DC

The major fundamental difference with the common-rail engines is the fact the system is under constant high pressure, instead of the short instantaneous bursts delivered via the jerk pump design of the 12 and 24 valve engines.



Sticky injector on 3G = instant blowtorch and blown piston.

Sticky injector on 12v or 24v = annoying miss, maybe a bit of blue smoke, that's about it.



The HPCR design is capable of some high tech fuel injection, but when it goes wrong it really goes wrong



There's been a lot of discussion about this, but the suspect cause of injector failure resulting in engine failure may come from wear metals from the HP pump migrating into the injector check valves. It would be nice to have some sort of filter between the HP pump and fuel rail. One cause of HP pump wear is inadequate and inconsistent lube qualities in today's diesel fuel. Running conditioner would be a very good idea!
