3rd injection event removal?
---AutoMerged DoublePost---
Exactly, and frankly a waste of time. If you want an ISB get the second gen truck and be done with it.

yeah I know the manifold swap isn't just a simple bolt on, and maybe a waste of time, but I want the sound of a ISB just not a 2nd gen truck.
If the used manifold I bought ever shows up, I'll be sure and snap some pics during the install and try and keep track of every part I use. So for others wanting to do it, the more you know the easier it is.
I've ridden in a 07 that had a stock 2nd gen manifold on it, he used the stock he351 turbo, added about 8 inches to his downpipe, extended his turbo oil drain tube, shortened his hot air tube, used flexible piece of rubber intake tubing off 7.3 powerstroke connected to a BHAF for his air intake. It sounded great by the way.
I have some differences in what he did to what I am going to do. Will post when I am done.

yeah I heard the same, but I didn't know about the power loss

I can't wait!!!!! Ya'll can say it's a waste of time if you want, but the sound of the CR compared to a 2nd Gen is the only thing that's kept me from gettin a newer truck. The sound of a 2nd Gen with the fact that it's much easier and less expensive to make more HP with a common rail.......what more could you want?

I like this thread! All along I have tried to get better mileage out of my truck. I have always said I have some power to burn if needed to get there. Hmmm..... (Guess how willing I would be to give up some power depends on the price of fuel really.) I too have noticed how much soot is in the oil in these engines. My oil is just as black after I change it and this is even before starting it the first time after the change! Wow!!
I hope we are talking about the same things here. I guess the '99 24V 5.9L and on has been referred to as an ISB engine. I found this article that had some good info in it: findarticles.com
What I mean by the same things are: I believe the third 'event' is just on 04.5 and newer Cummins and that it is just for emissions. I think the '03 and '04 had two 'events' and that is what quieted them down over the '99 to '02 24V's (Which have a single injection per cycle!). My friend has an '04 with a 305 HP engine. His oil will stay clean for a few thousand miles after a change. He also gets great mileage (I would say better than mine here; but, mine has always gotten 14 - 15 MPG since new. So mine is not a good one to compare to! That is another thread though....) If his only has two 'events' then maybe that is a lot of the difference between his and a normal '06 truck. I will have to check but I believe his is as quiet as mine.
That brings up the other 'same thing'. When you guys talk about changing the exhaust manifold to get that 'sound' out of yours: Are you talking about out the exhaust tip? Because I don't believe it will really change it much at all. Now, the turbo and the muffler (Even the size of the pipe for that matter) will make a bit of a change in the exhaust note.
Now, if you are talking about from under the hood; then that is a totally different matter (And I'm sure that difference is from a single injection 'event' per cycle as compared to the quieter more than one per cycle!).
As for someone who might be working on limiting the injection events, let's not all try to contact him or 'bomb'ard him with questions. If he is already experiencing problems that would only add to his problems. I will look into it and I promise: if there is anything there that will help others I will be happy to let you all know that are interested!

Dan, I was just refering to the sound coming out of the exhaust. I'm not really too concerned with the motor sounding the same. But it does make a substantial difference. I'm going to post two videos from YouTube so ya'll get an idea. Thanks to emp for tellin us where the second vid was. The first will be just a normal 2007 Common Rail truck with a straight pipe, the other will be a 2007 Common Rail truck with this 2nd Gen exhaust manifold mod. You can truly tell a HUGE difference and it really does sound a LOT like a VP44 truck.

Sorry, I guess my memory isn't that good. But you are correct in your years with the injection events. This is why the 2nd gen 24V ISB makes so much noise or clatter.
Consider this, a good friend, you know to whom I am referring to, said to me a while back that the more events you have the quieter the truck gets, the hotter the internals get and the worse off this is for the oil, the coolant and the life of the major internals. He did not say that getting a new truck was bad and in fact said that if you do the 2004.5 for an ISBE or the 2010 6.7L with the ISBE (Tier 3 SCR) is the way to go under different conditions.
What this means is that for stock power and reliability the 2004.5 is good to go, is trouble free and seems to be the best ISBE block made. The 2010 is on the other hand the best for those concerned about getting better mileage and still have lots of power. The issue with all trucks beyond 2003 for sure is that none of them are designed to be grocery getters - they need to be driven hard so cook all the coke out, and keep it out.
Power comes at a price though because as these numbers climbed throughout the early part of 2000 to now the mileage continued to drop. Reliability and power can only really be achieved by using a P Pump and that too comes with a price.
Where I sit with my 2002 - it needs a clutch and a set of twins - then I won't have any smoke, way better mileage than a new truck, no complicated SCR crap to deal with and oh yeah its PAID for!
Of course this is only my opinion.
The 3rd event, or extension of the main event as some say, doesn't fire until high rpm high load conditions anyway. Keep the rpm's under 2500 and there wil be little evidence of it and the mileage is so close the 2 event engines its hard to tell the difference.
The whole emissions, more soot in the oil, etc, is a function of the cam grind and the timing those things are much easier to change and while still technically illegal don't get as much attention as the wholesale reprogramming of a CARB certified fueling program.
Rather than fight with that its much more effective to change out the cam, add larger injectors, and advance the timing to recover the lower end power and keep the rpm's from climbing into the region where the 3rd event is problem. This mod seems to offer the best route for addressing mileage also. Some are rpeorting an average 40% increase in their overall mileage, much better low end power, and it does help clean up the dirty oil problem right after change.
Don't expect a drastic change on the oil as the newer oils are much better at suspending soot and the fact that the power ouput is double what these motors started out with in 1989 contributes greatly. Power makes soot which the oil SHOULD suspend and keep out of the engine parts.
