    How cold is your climate?

    We used to put the P10 on everything v8 to six cyl if its still available! as it was easier and cheeper to stock just one relay!

    If the mass flow tube is throwing a code the egr cooler is likly plugged or leaking coolant are you adding coolant?

    The cup Failure thing is usually ( usually ) accompanied by HARD STARTING BUT not always . your symptom and how it is manifesting is why i am suggesting cups the under hard pull it gets worse! head gasket failures compressor failures I Am sure can happen aren't common, cup failure is better than it was .but still prevalent NOT FIXED just patched! egr cooler is still on the table as a suspect! pull the front hose and look but usually you would be throwing efficiency codes or egr related codes of some sort!

    More than likly Cups! Stainless cup Did not totally solve this issue! Another bandaid attempt! At a fix! To get them thru the warranty period!

    If your not having starting issues EGR Cooler is a more common issue than compressor ! cups can still be an issue if your not paying attention! Is it doing this after a hard pull or all the time?
  8. fjh
    Nothing it’s normal ! if it’s starting fine then leave it alone!

    Check your fuel preasure!

    Could be the hose between the coolant manifold peices ! Very Common on a cold engine !A little more info would help! note that if the coolant has black oil in it it could have a failed engine oil cooler If it has yellowish look to it it can be a failed trans or fuel cooler If so equipped!

    Definition of crazy ! Doing the same thing over and over and getting the same result! 😠

    /be sure to check it the accesory relay is not dropping out when it quits check to see if the heater fan / and wipers still operate

    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!
  16. fjh
    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 !
  19. fjh
    Yes most common failure is injector cup injector seat failure

    Berry I miss the drop downs but YUP your right its a bit faster!
  21. fjh
    How many days down ? I can see a weeks work going away here! keep the updates coming
  22. fjh
    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
