Well at least merc learned from others mistakes and didn't cheap out.

As much as I agree with some (most? all?) of these comments about government overreach, lying, stealing, padding their own pockets, etc. I think it's best to keep the thread on topic of the CP3 change and the potential ramifications for current owners. If someone wants to start a separate thread...

On the topic of the EPA requiring the EGR, that wouldn't surprise me one bit. Government has a tendency to overreact to things and it takes mountains of data to change anything. They generally run on the principle of add it and forget about it. If nothing else it's simply easy to get stuck in a...

Everything that I've heard is that Cummins didn't spec the CP4, FCA did. That line of thinking makes sense as Cummins still includes the CP3 in their own crate engine 6.7.

FCA, Bosch and Cummins are prob the only ones that know. Currently there is no legal requirement to breakdown the number of occurrences in failures like this and there is no benefit to any company for doing so (oversell your positives, downplay your negatives). I don't think knowing the actual...

I saw someone reported on FB that a revised CP4 failed. Don't know any more details beyond that but heard another post on the thread the same. The revised pump wasn't on long so I doubt the numbers were good enough otherwise they would have kept the cheaper pump.

Good to know, if you find that I would be interested in taking a look. I wonder if the patent is still active and was not included as another cost cutting measure. Either way I'm betting that Bosch wishes they would have done a bit more R&D in the US market, after losing that contract for GM...

Regardless of if the roller fails first then causes it to rotate or it starts to rotate and then causes failure the issue remains. As was mentioned earlier there is a reason that pistons are keyed. I've heard there is a patent for a keyed piston and that is why Bosch decided not to use it. I've...

Does anyone happen to have any inside details from FCA/large dealers on what the future is for us CP4 owners? Curious if there will be a TSB or recall on the CP4. I'd imagine that FCA's primary focus right now is getting 2021s on dealer lots especially with the way the market is but curious to...

I'm with ya Ron. That said, it's also up to the states to enforce, so while I don't know what life will look like in 20 years it seems in the next 10 you should be able to tell where your state is trending. I agree with you on the "clean" likely not being as clean, but that's what I'm curious...

I hadn't thought about looking into the VM emissions info, thats a good call, I'll have to dig into that. Seems so obvious I'm surprised I didn't think of that.

Oh yeah, the end item itself is one thing in that it's easier to control, but there is also emissions from the manufacture, and delivery of those goods as well. I don't think I'll get down too far into the rabbit hole, as end of the day it's just not worth stressing over that small amount, but...

I'd rather not get into any sort of political arguments here. My point being that I think a lot of the emissions related research I've seen have been done with epidemiological studies, while I'm not going to claim NOx is good for you to inhale it's also not good to inhale exhaust gases from a...

Without getting too much into it since I don't want to open a can of worms, I'm actually interested mostly in NOx emissions. While I don't like the look of soot, nor do I have interest in cleaning it off my truck or "rolling coal" on hybrids I don't think the soot is all that bad. I think the...

So, I've tried to pull up some info but so far have struck out. I'm trying to figure out if anyone has data on emissions levels with emissions equipment on vs deleted. I don't want to get into the should you delete or not argument, that's not my goal here. My goal is to find hard data on what...

There is a lot of good information here. Not that I don't trust you but can you cite your sources here? I'm interested in the differences in diesel standards and additives and a more thorough read on the topic.

Brand new here, Bob said the news has been published, does anyone know where to find that? Curious to know more. Also, @cumminsturbofreak nice to see you here too! Maybe you won't need to make that disaster prevention block after all.
