More cummins crap

[WantedWolf]

Oh and Egon, thanks for rubbing it in. I know your in Canada, want to sell your truck?

Its probly even the 91-92 im looking for right?

At the dealer the other day I loudly said That I wanted an old 12v truck
Everyone in earshot said oh why would you want that and gutless junk etc.

No one spoke up for the 12v's because they were all out DRIVING there working trucks, not getting thier $#!t boxes fixed

Thats why at my job, we dont use Cummins anymore... Cummins is big and arrogant, and slow with warranty. Not what they were, say 10 years ago.

When we replace a 25 euro solenoid, broken within the first 20 hours of operation on a brand new machine, with a Bosch one from stock, they dont pay the warranty claim: Instead we have to order the same part from Cummins for 75 Euro and give the customer a free rental machine to use during the one week delivery time , waitong on the same Bosch part, just wrapped in Cummins paper !!

My injector pump must have really been working over time with a Lift pump reading of 0psi at idle, the reason it stayed running is that the transfer pump when toast will allow fuel through it and the INJ pump is picking up the slack pumping and sucking fuel. fuel that it also uses to lubricate itself, so it overheats.

I see the problem is really poor design of the lift pump on the 98-02's
The Injector pump has a steel timing pin housed in an alumium bore. the steel win friction would be enough to wear the aluminum alone (in time). Combine that with the fact they mounted the pump on the side of the engine wear it will recive alot of additional vibrations. Im reading the average get replaced around 45-65,000km.

If you have a 24v between 98-02 with no issues thus far...

Does anybody know of problems in this area [or any other] typical of the 2006 Cummins model?
Thanks,

No, the 04.5 - current model engines have the LP mounted in the tank. This is a much more reliable design as the pump doesn't have to suck the fuel all the way from the back of the pump. It starts pumping right at the source of the fuel and just pushes it along.

The injector's can leak on some of the 06's which can be determined by the tell tale white smoke or rough idle on start up. Part of that is from the lack of lubrication in ULSD. Just make sure you run a fuel additive regularly, such as Power Service, and this will lesson the chances of this happening. This small issue isn't an as common as the LP's on 98.5 - 02 24 valves dieing though.

Not to worry, a 2006 Cummins 5.9 does not have a VP44 bosch injection pump. It has an entirely different fuel injection system, the bosche common rail system, which uses an electric lift pump, which transfers fuel to a Bosche CP3 high pressure common rail fuel pump. This is a very high pressure fuel system, which requires in the area of 4,000 psi of rail pressure just for the engine to start, typical operating pressures can range from 8,000 psi to nearly 20,000psi, depending on load and boost. This sytem is very similar in design to the system used on the Duramax, and aside from the occasional injector issue, are relatively trouble free. Despite the rumors, most failures of the Bosche common rail fuel injectors have been traced to particulate contamination, as well as fuel quality issues. Although the new ULSD diesel has very poor lubrication properties compared with LSD, The bosche common rail system has been designed to work with ULSD, and failures of these injectors have more to do with ULSD absorbing moisture than its poor lubrication properties

If you plan on doing it yourself I wouldn't pressure wash the engine, there's too much of a chance of blowing water past the seals and then you've got real problems. .

A pressure washer used with common sense and a mild degreaser such as a 50/50 mix of simple green and water applied to a wet engine followed by power washing should not hurt anything. If you can blow cold water through a seal with a power washer, you are either holding the tip 2in from the seal, or the seal is leaking and should be replaced anyway.

A steam cleaner on the other hand can be harmful, as the hot high pressure water can more easily dissolve the dielectric grease on the weather pack electrical connections, and find its way into sensors and other electronic devices.

Bottom line, wet the engine when it is cold, then hit it with some simple green, then power wash it at around 1700 to 2000 psi and stay about 1 to 2 ft. away from it with the power washer set on fan spray and you will be just fine.

Some of the earlier 12V were somewhat anemic compared to later versions but to say that they are gutless junk is pure nonsense. You can easily pull 600hp without drugs from a 12V. You certainly do not need that much for the street of course.

The 12V is not without problems either. Two that come to mind are the infamous "dowl pin" which is a relatively cheap and easy issue to fix. The other not so cheap one is the "53" block. Seems the substandard block was cast in Brazil. The casting number can be found on the left front side of the 12V block.

I had a 95 ram 2500 with 5.9, only had 160 HP with the automatic, that thing ran so sweet and pulled nice. I did have to rebuild the Bosch pump, cost $2,500 at a Cummins shop, I'm sure they are the highest price around. I was real bummed at the time over the cost, but after I realized that was the only mechanical problem I had with that truck in 12 years.

I stuck with Cummins, even being a Guinea pig for the first year (07) 6.7L. this thing is super sweet, just miss the 5.9's sound
I just believe diesel power was meant to be housed in an in-line 6

In the rail ?, holy smokes
