I bought a 1990 Mack super liner
e7-400, 13 speed road ranger.
Bought it out of Ohio last year, I was able to get the history of the vehicle using MackTruckHistoricalMuseum.org. I found out it is a one owner truck from factory. I drove it home 230miles home never missed a beat. Although I did notice when I would accelerate from 45-70mph i would hear a clattering sound. I parked it up in the yard and have been doing little work to it here in there mainly on the interior. I did put a new oil pan gasket mainly to see if there were any chunks of metal in the pan or glitter, but everything looked good! I start it up every chance I get sometimes that’s weekly sometimes that’s once a month, regardless it always starts right up. While at idle theirs no clattering sound, when I drive it around the yard 20/30mph theirs no sound but when I get it out on the road 45-70MPH is when you can hear the clattering any idea?
