Never been a big fan of EGR however it's as with any newer technology, if you take care of the maintenance you should be ok with it. I think the heavy haulers had a lot of problems with it due to cooling system capability restrictions being maxed out so the EGR system was the first thing to fail. There are a lot of discussions on line on how to bypass, override or even eliminate completely. Beings I worked for the distributor that was never an option for us since we could be held personally responsible for a $10,000 fine plus the company got a $100,000 fine per incident for tampering with any emission devices. I guess we really pissed off EPA in the 1970's and 1980's by pumping up so many engines!! Our motto was "If it ain't smokin', It ain't workin'!!"
