High mileage ACERT owners

I have an 06 W9 with a mxs acert with 637000 on it with no issues at all just normal upkeep.

 

got around 620,000 on mine and just normal stuff. broke an exhaust rocker, had a couple valve springs crack, replaced both turbos, sleeves in exhaust manifold came apart than having to get both turbos replaced again. the second time the turbos got replaced was paid for by cat, said they know about the problem but only fixing as the sleeves come apart. thats all i can think of at the moment.

 

if i remember correctly it was around 4,000 give or take a couple hundred. it has been awhile so cant remember off the top of my head.

 

For me just the rocker upgrade and the turbo's are original. with some upgrades that I learned on here motor does a great job and mileage is a strong 6.25 to 6.75. 475 with 3:36 rears with LP24.5 and a 13spd. Turning 1300 at 65.I also have a turbo wing on top.

 

I got 568k on mine with no big problem's,also getting mid 6's on fuel mileage running 65 # 1475rpm.

 

What symptoms were you getting before turbo's went out,only reason I ask is mine started making a kinda rattling noice at high speed's and seem's like nobody can narrow it down,truck run's fine does not lack power or fuel mileage.

 

first time wasnt any symptoms, i started it up to let it warm up than took off and had no boost. was fine before i shut it off. the second time i kept hearing an odd noise around 20 lbs and finally took it to the shop that changed them originally. took off one turbo and noticed the fins were all chewed up from the sleeves coming apart. both looked exactly the same.
