Good to hear of the progress finally, definately keep us posted for the end result !

There torquing method is out to lunch in my mind tightening and loosening makes little sense in my mind how ever with such a wimpy bolt this method may be needed!we did some the other day we used oil! WHAT ever! any assembly procedure alterations will not totally correct a poor hold down design!

Yup oilly! also fairly common as strange as it may seem is injector orings fuel can leak up by the injector hold down threads ! and the fuel transfer pump shaft seal can leak another semi common issue!

Well your dealer did well turning it around quickly anyway! hopefully Mack don't wash their hands here keep making noise ! in their defense These power issues can be a bear to chase down! But if It aint right it aint right!

Mackpro have you had any cup / injector failures on the common rail units in you area yet? Not a one here yet !

Yes most common failure is injector cup injector seat failure

Berry I miss the drop downs but YUP your right its a bit faster!

How many days down ? I can see a weeks work going away here! keep the updates coming

Bro I got to ask has this truck been having any starting issues? We have had it where the cups are starting to loose seal and it causes the unit to never finish a regen for what ever reason ! once the cups were repaired life was good! just an observation!

Maxidye has a huge pull range to enable the use of a 6 speed trans operating range from 1150 to 1700 not uncommon econodyne needs a multi speed trans to live!

If it were mine for the cost of a set of rings some bearings and a pan gasket while the heads were off, I would run a hone down the jugs and install new rings just sayin! Never saw pressure blowing out of a front Teflon crank seal. ( me neather) Also if the bloby is worse under power it can be a turbo seal issue also very common with the AI and some AC turbos! We also have several trucks running around with the cooler blocked off totally no coolant running thru or egr they perform OK ! sumthing to think on! be sure to replace the rocker bolts in any case

the most hp E7 mechnical engine you will find is 400 , real small window 3 years maybe! after that mostly electric 427 454 electronic only

The sex slave valve was mounted on the fuel rail incoming line on the older first gen engines yours may not have it' it was done away with after a few years! In my opinion as long as your ecu fuses are good and the connections at the firewall pass thru are good no worn thru wires ect: you need to pull the pump and have it repaired! the rack controller is likely toast!

The elab valve engages with the turn of the switch the engine should run with out the rpm sensor it will not run without the timing event marker on the pump but will throw a code and the check engine light will be on for both i believe ! Most often By what your describing the rack control has gone west in these cases the pump has to come of and sent to a Bosch Fuel pump shop and parts replaced!

I would be squealing pretty loud about that! If they plan on doing R AND D on your head and valves the truck could be down for two weeks or more ! they need to supply the dealer with a new head out of the box MIN and just put it on there Ive seen this shit happen before ! I would recommend you make lots of noise!!

Yes Injector harness issues have happened the harness is all one piece!

Sounds to me your doing it right the only thing I have to contribute and you probably already know and has been mentioned can't say enough times is SELECT SPLIT switch it and break torque right away ! Don't switch and wait! it wears the hell out of the shift fork if you pre select and wait! that little grind you hear once and awhile is acceptable ! But worth experimenting with different techniques to correct IT ! IE: engine brake on /engine brake off / usr the clutch don't use the clutch on the offending gear! experiment !! The 12 speed suffered from this same issue back in the day and there were guys out there that have it down pat! I AM NOT ONE of them thou ! Teck said it Here IMO- You can tell a good driver by front fenders and his slider clutch wear. Experiment!

So Whats the ETA on this Venture Data recorder that is? Another month?

Well its another week any farther behind?

Takes 6/8 hours if ya got parts on hand it also can be a loose pinch bolt on the split fork or range fork can cause the same symtoms Bit less costly how ever!!!!!!!!!!!!!!!

Yup Agree with this statement your likley going to have to replace all of it, you may be wise to go neoprene! the grease is a good set up (if looked after) Meaning you jack the truck up take the weight off the saddles and grease it! greasing with out jacking it up , for the most part your just keeping the dirt out.

Finding people that give a rats ass about what they are doing for others these days is a struggle ! Its just a job , just a pay cheque, no pride in what little work they do put out ,It is a real piss cutter trying to find good folks that want to work and want to please ,Having said that A lot of this mentality has been past down from the top mack / volvo its self is riddled with this same thought process ! Society in general I Guess Spoiled Brats!

Unfortunately if the injector cup issue is an on going thing and has been for years on all HP ratings of these engines up to this last ear the change to common rail seems to have changed things (HOWEVER ) the jury is still out on these. so far do good. in our area for the common rail ,WE Will SEE! I am not holding my breath!.

Stat is you first step Id think

We will see how that goes!
