I beg to differ. Get in a flat bed F450 tow truck with a 6.4 and head towards a bridge toll booth with both feet standing on the brake pedal doing 80+. That happened when they first came out and i was in my first dealership. Haha that was the best day of my life. Customer complaint-Cleaning Exhaust light comes on often and sees smoke out the exhaust. Report findings. I didnt have the lap top so i figured eh, ill get on 209 head towards the kingston rhinecliff bridge and see if i can get it to act up... Well 5 minutes of doing 50-60 and cleaning exhaust light came on. Truck started to make grey smoke out of the exhaust and the whole truck started to vibrate. Me being me, if somethings going to quit im going to lay into it to keep it running. Well i lay into it flat to the floor its not gaining any speed and im thinking the fires going to go out soon... Boy was I in for a surprise. All of a sudden it comes back to life. Throws me in my seat and just goes so im thinking cool! Whatever booger was in it just got blown out. Im coming up along side of a prius with all windows down, and filled the interior with black smoke
well i let off the throttle and its still going. Oh dear.... This isnt going to end well... Im passing everything like its standing still leaving a trail of thick black smoke so i turn the strobe lights on just to clear the way and hold the horn down. I have NO clue whats going to happen. (need i remind you i was fresh out of college the only automotive experience i had at that time was building race cars, and mud trucks and was in my 2nd month of my internship only diesel experience i had thus far was with 6.0s doing egr/oil coolers, ripping cabs off to do head gaskets, and change injectors) So i see the toll both coming up and i call the shop they patch me in to my mentor a sr master lead tech of the shop. He says i have a run away and to put it in nuetral and coast to a stop get out and stand back. Easier said than done. i got within about 50 feet of the bridge before i finally got it stopped. I got out set the e brake and stood by the control levers for the flat bed. It made one hell of a clatter before it quit. I was never so embarrased in my life. Standing next to a ford pluming smoke everyone pointing and smiling or frowning because i covered their car with soot.
My rear bit the seat Especially when i got so close to the bridge. I thought for sure i was going to run it and i was going to aim for the Easy pass and plow through it and lord help whosever in front of me with no room to pass. Half an hour later i get back to the shop in a big rig tow truck with the flat bed on the hook, everyones clapping and cheering and laughing. They said i broke my cherry and can now call myself a diesel technician... Luckily it didnt anger or upset my service manager or anyone in the shop. they just said better it happened out there than in the shop and asked me if i was okay if i was a nervous wreck and if i wanted to go home to which i responded nope im good just want to get this thing torn down. Then my manager says "Ask your mentor what happens when they do that inside... Youll be hated so quickly and probably have tools thrown at you"
That job needless to say sucked couldnt turn the engine over by hand to get the torque converter nuts undone even with a cheater bar on a 3/4 inch ratchet with a 38 inch long handle. Had to remove the light bar and crap to get the cab off and it just fit in the shop pushed under the landing in our bays. Ended up pulling the motor and tranny together got the PTO off, removed the transmission left the torque converter on the flexplate and that went with the motor back to ford for a core.
Most ungodly noise you will ever hear is in a 6.0 run away. 6.4 is so muffled from the DPF DOC Muffler and rest of the crap in the exhaust. They just make a loud BRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRR
And What Ryan says about detroits is true, They will run in reverse. Spit smoke out the intake and will clog the interior of a rig with smoke within seconds. Was witness to one of those as well. Guy had a kenworth cab over with a 8v71 and stalled it it rolled backwards he dumped the clutch and dove out the door shortly after it fired up.
