😃 good on ya buddy! Agree totally!

Yup all about the money! I stopped by our place today they say that they lost another pair of guys to a Volvo trash machine outlet! Now have 3 technicians and 8 apprentices imagine the quality of work leaving the shop! Mean while you have to teach morals as well as mechanics to these lazy shits that don’t care about nothing but the pay cheque! Couldn’t even think about going back to that environment!

Yup good on you for posting stuff ! Really helps when people care about what they do for other’s! In the day and age it seems folks don’t give a rats ass about much! Many guys here are helpful! It’s a good thing!

These gaskets are garbage ! I have said many times these guys thru out all the good Mack ideas instead of using them! The egr oring on the aset was a perfect example if you must recycle exhaust gas this was perfect oring and flange to do the job! Engine mounts another good example ! Nothing simple about any of the Volvo trash ideas! You said it in your previous post there should be a law!

I did not have much to do with red engines ! Work wise that said I did however have input into how they were diagnosed! You simply have to try and pay attention to what you hear and see and apply some old school no how! The water trick can be used to find exhaust and head gasket leaks you can’t see as well!if it’s making a sound try and change the sound!

The pressure builds both directions so the closed valve actually helps build pressure by spooling the turbo at lower rpm’s I believe!

Yup for those unfamiliar! the best way to find those is to do a regen get the squeal going if the truck will allow you to and pour some hot water over the suspect area’s and listen for the sound to change! At least that’s how our guys tracked these down!

This here is entirely experience based Crap shoot! start with what you know and see and what you don't! if the egr valve opens on command and the cooler is not cloged and the differential pressure sensor and venturi tube are clear and show to be working on the screen ! then you might want to tri the turbo first! BUT ITS A pricey nuke! It all depends on which ammo you choose to load the canon with and in what order ! You tend to try to use the cheapest part first ! However Had he pulled on the turbo first and tried it it likely would have saved all these other parts ! BUT its the most costly so you hope for the best by starting cheap ! Its a total crap shoot Unfortunately! there is nothing in this trouble shooting chart on this other than experience ,good logic and your best guess and good intentions! Sad but true!

Agreed! These turbos can choke up with carbon and stick sum times only when hot then won't stroke out enough to make heat! And then Just compound the problem with more carbon!

Thanx for posting your fix! Sounds like they got into a parts throwing situation in unfortunately sometimes that is what has to happen!

So is it an air operated or cable operated?as pictured? The should be a stop on the linkage there ! I believe it’s a sliding gear in there! I have changed the shaft on these with out removing the whole lump but it has been years!

Picture 1 is driven off the main box counter shaft and has five selectable speeds if I recall! On a 12 sp trans !

E6 won’t handle! E7 maybe for a while! Wouldn’t want to drag much over 500 for to long ! Just my opinion!

Ahh good to know!

I doubt Mack will not let you have the Xt program not enough cooling will be the excuse or a non Mack drive line will be another excuse!

Not wrong just the way you think. I thlnk like you also! How ever when you’re being squeezed for old parts that they are trying to make extinct the writings on the wall!

yup it’s deleted so it’s a crap shoot !Takes your chances with this! Hopefully don’t crack the head! Seen so many isx turn in to shower heads by deleting with the wrong programming! Could be Just a night mare!

Make sure you check them slaves as v mentioned! Hopefully injectors cure it how ever grasping straws and chucking parts is expensive!

Joe you would think it would be throwing a code if the cam was off a tooth at least that’s what our guys experienced! I think he pulled the valve cover replaced the the brake valve! Milkman is likely on to it the delete program is likely causing an issue!

7th injector still hooked up? engine brake valve sticking? half stuck? just shit to think on! If the engine brake is full stuck the engine will start then die a soon as oil pressure is established ! If its part on will run rough and still be fueling! smoke! we had these valves faulty right out of the box ! Just sayin!

Is it throwing up codes ? on the dash! these have synco issues in certain gears 7 th if I remember correctly! does it have 2 speed reverse?

Me too ! 🤣 That said the vgt could be sticking not uncommon even when not deleted! remove the control motor and check if the control rack is moving smoothly! DON'T break the bolts! 😅

With FIC module would make it vmac 1!

HOW????????? you answered your own question Joe! her oldest is a drug dealer,

Exactly! You can triple the HP on a E9 But how log will it last is the issue! the E6 as Paul stated there even at 285 maxi dyne was susceptible to this they did make a 315 thermal dyne as stated before in another thread there was a reason the E7 came along! sure you can turn it up but DO YOU Really want to?? If you want to keep your toy alive just leave it! in my mind A half turn on the screw is all I would consider myself ! You don't want to be getting your foot into it for any serious work thou !
