Oso2 Posted December 9, 2021 Share Posted December 9, 2021 I've heard not good things about the e7 EGR ASET engines from 2003-07. Can they be made to run well WITHOUT deleting them? Is it worth buying a truck with one? (Assuming that there aren't any pre-'03's available.)

Joey Mack Posted December 17, 2021 Share Posted December 17, 2021 OK... in my opinion, I know these engines... If it is an ASET CEGR... run away, run very far away!!!! the ASET IEGR's are a bit better... however.. they have ceramic lifter rollers and I hate them... and you will too when you have to do a cam job, for the dumbest reason that a real engine would have survived from... Jojo... I have more opinions on this.... Quote Link to comment https://www.bigmacktrucks.com/topic/68896-can-asets-be-made-to-perform/#findComment-485364 Share on other sites More sharing options...
Onyx610 Posted December 17, 2021 Share Posted December 17, 2021 Listen to Joey…We have three AI engines at work in dump trucks ranging from 03-05. We haven’t had any issues with them at all and those boys can test a truck out. They don’t get ran every single day like most trucks but its definitely made up for when someone’s in the driver seat. I swear Mack should send us trucks to test out… Quote Link to comment https://www.bigmacktrucks.com/topic/68896-can-asets-be-made-to-perform/#findComment-485371 Share on other sites More sharing options...
Onyx610 Posted December 17, 2021 Share Posted December 17, 2021 They run good for a 300 and 370hp. The E-techs we have…id take them over ASET if I had the option.

Oso2 Posted December 19, 2021 Author Share Posted December 19, 2021 (edited) What about the ac 427's and 460's that came in the Vision until 2007? Or would it be better to find a Pinnacle with an MP8? (assume pre-emissions or deleting isn't an option.)

Oso2 Posted December 20, 2021 Author Share Posted December 20, 2021 My understanding is that the AC's were e7's with EGR attached. What sorts of things went wrong with the 04's. Why were the 07's just okay? And how would they compare to a 2017+ mp8?

Popular Post Joey Mack Posted December 20, 2021 Popular Post Share Posted December 20, 2021 The 04' was another new begining of too much B.S. bolted to the engine, and more sensors.. Personally, I do not like the ceramic lifters.. If the ASET is a CEGR ( cooled e.g.r.) then you will give your wallet a 'workout' The exhaust system at the engine is very expensive and the EGR valves dont last very long, and at a grand a piece.... well.... you get it.. heck the EGR crossover pipe with the 2 sensors in it is $1700.00.. and on back order at times, and forget replacing the cracked exhaust manifold center section... The MP's.. Strong engines. but many exh. repairs will be done. I keep saying it's expensive.. all repairs are expensive, but the frequency of some of these repairs 'chap's my a$$'... When I was working in the Mack dealer a few years ago, I would cringe, on behalf of the customer who was trying to keep his truck on the road, when he got a bill for $5000.00 - $8000.00 for exhaust system repair, and then have to bring it back because the MILF light came back on... OK,,, time for other opinions.. jojo 3 1 Quote Link to comment https://www.bigmacktrucks.com/topic/68896-can-asets-be-made-to-perform/#findComment-485600 Share on other sites More sharing options...

THe first year of 2004 of these trucks we sold had 20 in stock sold ten, the other ten became parts trucks for the best part of a year! couldn't keep Turbos on them ! Mack ran out of turbos so we ended up robing trucks to keep guys running ! Manifold studs broke ,coolant push And the imfamous Fuel line Feasco ! The list was long! They finally got a handle on it in 2005 after the damage was already done! F**king Embarrassing if you were a dealer! or a real Mack guy! 1 Quote Link to comment https://www.bigmacktrucks.com/topic/68896-can-asets-be-made-to-perform/#findComment-485718 Share on other sites More sharing options...
