Noticed cooler EGT's when towing, Turbo seems to spool faster, Engine brake seems to operate at even lower RPM's.

None of which is related to anything you bought and installed from Banks.

Now this is something that certainly warrants discussion.

There is a company in Canada that dealers can send the unit to be repaired. I was told turn-around time is about two weeks.

This bolt killed my neighbors truck same year, nearly the same miles. I swapped mine out for the Banks unit. $1k is cheap insurance as he got hit with $23k bill for engine replacement.

In my opinion it was completely worth it.

You do know that you could get the grid heater delete kit for about $300 right? Banks is selling on their name and fear mongering and promises that don't really do anything more than any other vendor.

Your tubo, EGTs, and exhaust brake have zero to do with a grid heater delete. Exhaust brake is attached to the turbo. Turbo receives air from the exhaust to spool it, and EGTS again come from the exhaust side. The grid heater is on the intake side. The restriction on the grid heater is not enough to notice any improvement. The only way you'll see improvements is if you tune the truck. Aside from that, the factory tuning will adjust the fuel/air tables to overcome any mods that you might do. You'll still make the same HP and torque as you did before.

I tune/delete all of my Cummins trucks. I run a stock HP tune. If I've created much less restrictions and "should" see more airflow, more fuel, etc... how can I still run a tune that still has stock HP/TQ? Think about it.

Banks is good at what they do. Pay no attention to the wizard behind the curtain.

I thought about it. You didn't do anything about the air intake restrictions. You handle the exit, but the entrance is the largest choke point.

The stock entrance can handle enough airflow to support ~600HP which is far above what 99.99% of the people are running so there shouldn't be any choking going on. (this was dyno proven but some of the top tuners in the business).

Irrelevant to my response.

The only restriction that I did eliminate is to remove the throttle valve. That does slightly decrease the intake restriction. But to mtnrider's point, the current intake is not restricted as much as most think. The intake is not the issue. It's the tune and the exhaust restrictions.

My point is to prove that the tune controls the power levels much more than restrictions.

Ya that was good...I laughed pretty hard on that one

Just to add into the pile. I know someone personally who lost their Motor due to this Bolt. Took out Motor, Turbo and all.
Truck was under warranty but he was without it for months.
Just so you know, they completely removed the Cab from the Chassis to do the Motor Swap.

So the bolt made it through the cylinder, past the exhaust valves and into the turbine side of the turbo? Did it somehow make it past that turbine, through the intercooler, and back into the compressor side of the turbo?

Here's an illustration to help with the questions above.

That is not physically possible. Did the bolt come out the exhaust and find its's way back into the air intake, past the air filter and through the turbo?
You are full of it. :manos:

Not sure why you think it is impossible for it to take out the motor and turbo?!?! It is definitely possible!!

I guess anything is possible but in all the years the grid heater bolt of death has been discussed, I've never read the turbo has been taken out.

From the pictures I've see, the grid heater bolt becomes part of the piston. Even if there is a loose piece of the bolt, it would have to find its way up through the exhaust valve and then find its way to the turbo.

Have you read or witnessed the grid heater bolt issue taking out the turbo?

Those of you questioning why the engine and turbo was replaced, the question was answered in the post... the truck was under warranty and the entire assembly was most likely shipped back to Cummins turbo and all (usually requisite of warranty replacement). In the big picture it cheaper to replace the whole assembly. Pulling the cab makes it easier.

I guess anything's possible, but it would be a one in a million shot.

It would have to somehow manage not to be completely press molded to the top of the piston and instead break into a lot of really tiny pieces, ricochet past the exhaust valve and make a direct shot (without getting stuck) through the exhaust port..

Then it would need to lodge itself in the turbine wheel while the engine is making max boost. It could theoretically I guess, lodge itself in the turbine wheel and cause it to instantly lock, which I guess could also cause the shaft to snap between the turbine wheel and compressor wheel.

The shock from that could cause the compressor wheel to shear off, catch the side of the housing, snap off a piece of the wheel, and send it through the intercooler, ping pong around through the small intercooler air tubes over to the exhaust side of the cooler maintaining max velocity and back up into the intake.

This is a bigger reason for concern over a GHB failure... people "know someone" who had it happen or read about it in a thread online. Only a select few have actually experienced it. This thread has Gale Banks mouth salivating.

I am telling what I was told. Nothing more.
I did not see Motor or the Parts or the Mechanics Report. I am only telling everyone what the Truck's owner told me face to face.

Attached is a picture of a Cummins Piston that has supposedly seenthe failure.
Notice the small pieces embedded into the Piston? So let's just say that perhaps some of the pieces did not get embedded and travelled on out the exhaust Valve?
Possible.....I'd sure say so! Is there something that would catch or stop them before they hit the Turbo, I do not now but if not then your Turbo is done as soon as these little bits get to it.

You are full of it.

I believe your idea of how the exhaust gases are routed is incorrect. The Exhaust gasses do not go around and go back through the Air Filter.
The Exhaust Gases drive the Turbo and without them the Turbo would do nothing. EGR redirects some of the gases back into the intake system but not through the Air Filter.
Attached is a simple picture of the concept for you.

I suggest before telling someone they are full of it you understand how the system perhaps works.
