Noticing this too! Our longest running machine shop closed here last month only one mom and pop shop left in town now! Sad ! They had been here since the early 60s My Dad used to use them ! The throw away society has crept up and over taken most of these places! And the walmart stand in line type places have taken over offering dollar store parts and very basic machine work or mail out style machine work!

You might lose a cup of oil by replacing that line just do it!

We would use the synchro kit from PAI over Mack solely for the price for 13/18 sp mack trans! Every bit as good ! we Never used PAI for Gears How ever I wouldn't hesitate if given a choice! We have a place local here quicker to deal with for gears as down time is important to most guys as well!

Can’t oops 😬 Fixed it for you bro! 🤣

You can't go far wrong with pai parts !

Well at least your not chasing your tail now! 😪🙄 Back order ECUs Possibly suggests to me there has been issues ! Suspicious! Did you try reflashing the trucks original numbers matching ecu ? Don't think you can reflash a donor!

Bro ! likely is the operative word there! Grade gripper sticks You will likly get a clutch overload Code come up on the screen AND I would like to think the fuel will be dialed back momentarily But I'm Not A guru on these I just Dabbled !

yup! E7 highest HP Version of this 454 ! big change to fuel and block design> Then changed to ETECH! 460 and 460 XT> 487 hp (alleged )

Depends on who you get to do it! Like anything there are folks that are good at what they do ! And some that think there good!

Its impressive ! By the way we had A customer years ago that bobtailed his dump truck to from Vancouver Island to Oregon ! And achieved 9 MPG! E6 Super high rears 3:87 ratio I believe! We also had A customer that Achieved 7-8 mpg with a 440 V8 long haul Both these guys really worked hard at it thou ! focus was on fuel mileage!

Wouldn't hurt to have him replace all the rocker bolts! they are torque sensitive !

If it doesn't then disregard the comment It was just a thought! These gave quite a few problems on the units that have them! Sorry not being much help here just Grasping at solutions like you!

Good Call Bob! The Dyson Elite!!

Yup!

yup usually have to start them moving with a diamond punch! best to take the plug out of the end first! I made a special socket for it as well!

Like Heinz was saying the Japanese trucks are the worst! We had a Hino line for a few years they were in the dark ages as far as parts look up when computers were well under way here they used the micro fic for years after! must be a translation thing don't know!

Quite Honestly and this is ( My opinion) The Best parts training in my mind is for the parts guy to spend six Months in the Shop with a good Mechanic! See what Parts he has to change AND Why ! 😪 A younger parts guy with the computer savy is best for that Impact program as its so user unfriendly😡 ! I observed when we change from Real Mack To Volvo Mack The older parts guys struggled more with the Impact Program! How ever Experience second to none when it it comes to finding stuff really helps, just like the shop end Experience is A big important portion of both jobs ! I was fortunate I worked in a shop I was allowed to follow the parts guy to parts locations so new where to get stuff ! It got harder when Volvo screwed with things as the numbers had no meaning Just an assigned number!

Trim code installed ? Each time? Can you do a Reflash on the ecu? Maybe something has gone sideways in there!? The learning at limit thing is an odd statement Kinda points to a programing thing in my mind! something is not making sense to the ECU and it is shutting down number 4! But just me I'm a Gray engine Guy only Dabbled in MP stuff! You Might tri Reflash first before swapping or getting the parts canon out again Stupider things have happened! we had ECUs do weird things before and it sounds heat related! from what you've been saying! 😡 and less labor intensive! cup of coffee and your Eyeballs is all that's entailed !🙄😁

By what all has been said here so far My Guess is EGR Cooler or turbo! what I Think your seeing is exhaust gasses passed by the turbo seals and a small coolant leak there as well! Get an oil sample to start with ! And move on from there in my opinion! It gets worse as the load is applied There is a small amount of boost at idle for EGR purposes accounts for the steady wisp while idling! Oil sample then grab a straw! Pull the pan and pressure test over nite Problem with MP is (for lack of a better term is the butrus plate) it will make it hard to pin point where the coolant is coming from! Or Last resort Get out the parts canon and start shooting parts at it starting with the cheap EGR cooler then the turbo Don't recommend this However............... Note ! Usually ! If it were an EGR cooler there would be mass flow codes!

Not sure you’re truck has this but there was a fuse panel to to the left of the clutch up the side that gave issues at a point epdm panel think it was called there was a tsb for it we replaced dozens of these panels and installed a bandaid boot around the panel

Yup agree with that ! I found my self getting grumpy with our parts guys at time’s waiting for parts not taking in to consideration they get busy with customers and other folks! Go get the stuff you self and get shit for that ! They get pissed cause you did so! Happy to be away from it truthfully!Worse is when the bring in the wrong parts pretending they know what you need! Used to piss me off too!

don’t lie you hate his guts! 😂

That was the key guy I was talking about in the other post 😂 yuo we’re hatin that parts dude!😃

You done good Joey! Not much changed just the addition of the drive by wire! The mechanical is the same! What I hated the most was the change to the bolt on cam gear! To sweat on! Dumb! Added insult to injury when having to do a cam job in the bush!
