Mudman74 Posted December 3, 2020 Share Posted December 3, 2020 I would need a little more info on the engine. Is it an IEGR engine? We have 4 of them. The power band is higher. They really don’t build power until 1300-1400 rpm. Not a bad engine. Did have oil leaks from the exhaust manifold bolts for a while. Also the Oil pressure sensor On the filter housings leaked on them. All of ours are over 25000 hours. Quote Link to comment Share on other sites More sharing options...

rickm688 Posted December 6, 2020 Author Share Posted December 6, 2020 Yes the engine has EGR which was replaced this year and the hours on the engine are 20,458 Quote Link to comment Share on other sites More sharing options...
OldRedMack Posted December 6, 2020 Share Posted December 6, 2020 So its an external egr? That would be an AC engine. Different than the AI engines with internal egr. Mack had 2 different versions of engines, so need to know if its a AC460 or AI460. Quote Link to comment Share on other sites More sharing options...

Joey Mack Posted December 7, 2020 Share Posted December 7, 2020 If it has an EGR cooler below the huge turbo....Then it's a CEGR..... "Cooled EGR" ASET..... "Application Specific Engine Technology"... ASET... If There is no EGR cooler and a basic turbo.. Then it is an...IEGR engine... Internal EGR... Still an ASET.... Of course I would rather have the IEGR.... There's no module, air pressure feed, and filter to get clogged, also no EGR tubes with sensors in them.... Blah, Blah, Blah...... anyway..... The CEGR version is the nightmare.... Good luck... I've done a bunch of turbo/ EGR repairs to these... and the IEGR engines of the same years just keep running... Keep the oil fresh and the valves adjusted, fix exhaust manifold leaks, and drive on!! Quote Link to comment Share on other sites More sharing options...
