What year were EGR valves added?

Next its gonna be the blood of truckers being injected into the exhaust. #### EPA.

What you have to watch for is when the truck was built.

If you ordered a truck in the later part of 2003, you might expect it to show up with a 2003 engine, only to find it had a 2004 emissions compliant engine under the hood. Usually 6 months before a year change, machines are already built for the upcoming year. So even though you ordered in 2003, the machine was built as a 2004 model year truck, therefore it has to come with a engine compliant for it's model year.

The newest used truck that will give you little to no problems would be a 2007 model year with a Caterpillar engine. Once 2008 arrived, DPF's arrived and the Caterpillar twin turbo design became significantly more complicated, unreliable, and costly to repair.

By all costs, avoid Cummins ISX engines. Everyday I see another one in the shop that blew parts through the block or the oil pan, some as low as 250,000 miles. There pistons and connecting rods are exceptionally weak. Cummins has gone way down hill since the days of the N14, and many diehard Cummins fans only recommend Cummins because of there good experiences years back with the N14. Old engines and there reliable records mean nothing now. We are in a new era of technology and engines all together.

 

I swear I'm going to quit posting info on here if you lazy ######## don't learn to read before posting. The correct info is in that link, and it has not one thing to do with the chassis year model.

As many trucks as possible, in the first year of new emission standards come with the previous years engine! The exact opposite of what you just posted. These are heavy trucks, not just big cars!

Study Sam Clemons..learn when to speak from him!

 

The '07 Volvo I got in Sep 2007 with 29 miles on it had a DPF.
The 2010 Shaker I got in August 2009 with 900 miles on it had DPF but not DEF.
The 2011 S**Spreader I have now, that was placed in service in January 2010 has DPF but not DEF.

 

Any Cummins or Detroit engine built after September 31, 2002 will have an EGR system on it.

Caterpillar engines used the Acert technology to avoid the EGR system requirements Detroit and Cummins uses. But the CAT engine meet the same emission standard as they do.

So to answer your question, you want a truck built with an engine in it that was manufactured before September 31 ,2002. The latest trucks as far as the truck manufacturers is concerned would be an early model 2003 truck. There were 2003 trucks built up to January 2003 that had the 9/31/2002 and earlier engines in them without the EGR or Acert technology systems on them.

CAT could not build the Acert in time to meet the 9/31/2002 emission stadard. CAT built roughly 33,000 engines with an engine serial number prefix MBN. These engines can be back dated with ECM changes that will basically bring them in line with the pre 9/31/2002 engines. These engines are nicknamed the "Bridge Motor" and trucks with this engine usually sell at a discount on the used truck market.

 

do the detroits have the same problem with the egr as the cummins

 

Correct. My ISX was made in October of 2002, and has EGR, a 2003 model year truck.

 

i love my 3406b more every day!

 

Well, the EGR in my 2006 ISX died in the closed position some time ago. Now I effectively have a pre-EGR engine. Will never change the EGR valve. Playing with the option of just rebuilding this engine (without changing EGR valve), and going again.

 

yes they do have problems also
