RAYSFLIGHT Posted November 30, 2020 Share Posted November 30, 2020 Wondering if anyone has experienced any issues or problems with this engine. Quote Link to comment Share on other sites More sharing options...
Dirtymilkman Posted November 30, 2020 Share Posted November 30, 2020 The only problem is they quit building them. Million mile engines, excellent torque and set up correctly, they'll out pull anything 450 hp and under. What nitrates in coolant and keep spinner filters changed when you service truck. 1 Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted December 1, 2020 Share Posted December 1, 2020 The engine you have ,,, if it's a '99... Is An E-Tech... I remember the old timers I worked with 20 years ago, telling me that they were junk, the E-7 was the last of the "million mile engines" that Mack made..... Yes The E-7 is Great.... But after many years I have come to respect the E-Tech.... Yes, It had cam issues, caused by bad roller lifters... and some issues with the wimpy engine brakes....Mack tried to improve that with the "top oil feed" update.. it helped along with the improved oil pump.. I have drivin these trucks for years and ..."yes' built a couple dozen of them too... I wouldn't be afraid of owning one. After 2002, They went a little crazy with cermic lifters and spring loaded pushrods...Blah, Blah, Blah.... In my opinion.... You have the best one.. Too bad they didnt have the power leash engine brake on youre engine,,, That to me is what it needs...:) Jojo... Go Bulldog!!! Quote Link to comment Share on other sites More sharing options...
