Ok.. next.... who did the valve adjustment?? I'm a "Stickler" about valve adjustment's an Mack engine's.. this is a side thought... Let's first address my previous post.. you will have a bunch of guys that will join in and guide you... jojo

ok.. without going deep... make a small gauge jumper wire.. to reach from the pos. on the alt. about 3 feet long... crimp an alligator clip to each end, ( you will save this tool for later diag.) climb up there, and un-plug the 2 jake plugs at the valve cover spacers.. you will see an 1/8" pin sticking out.. with the engine running at low idle. simply, clamp one clip to the Pos. on the Alt. and use the other end to touch on to the jake pin at the jake spacer... . It should activate the the jake on that head, and cause the engine to stumble... if it does not stumble the engine on that head, then the celeniod is either unhooked/cut under the valve cover, then you fix the wire.. or possibly the celenoid is bad.. it is a simple test, that Work's.. Jojo

I want to know,,,,-ish.... I bet we look like a bunch of wimp's... anyway, we have many times more normal people than the freaks that are broadcast around the world.. Unfortunately,, we have a F'd media that only focus's on what destroys us.. jojo

Just for kick's... unplug the EECU plugs and see if there is engine oil inside the sockets on the EECU... Do you have a list of codes? if so , post them... Cups and injectors is highly possible.. when the DPF was cleaned, was a forced re-gen done using PTT or equivalent, along with a soot level re-set and a 'learn data reset'?? how about an EECU software update?.. just curious, wouldnt the engine be an MP-8 in a CXU?? no biggie, just curious... I guess its an '09,, no DEF,,, jojo

yeah, i remember when this fruitcake came into power this year... I felt like puking.. Still do... Its like we are becoming a freak nation... jojo

May I suggest that you post,, the model/year/engine/tranny/ last 6 of the V.I.N./ and any related info... Welcome to the 'Dog House'... jojo

Hello 'Q'.. welcome aboard.. You commented on an old posting. How about telling us the year and model, engine, tranny and the issue you are having? You wont believe how many smart guys are ready to help you.. jojo

That is awesome.. I'm so glad it was a simple fix.. I feel like most of the time, the cause is something simple.. It was good of you to post the fix. I bet it ''Purr's like a Dog'' now... jojo

I just made a repair on a T-310, with the same issue.. I pulled the range fork out and found it had worn tip's,, but really not the worst iv'e seen,, i re-ringed the piston and cylinder and replaced the fork $600.00 for the fork.... (Through MACK) Why ???..... I test drove the truck, it range shifted correctly.. Look at PAI for the parts... Do you have a tranny re-builder in your area that will sell the part's? I use "Overdrive Rebuilder's" In Concord N.C. when ever I can... jojo

Happy Birthday Sir... jojo

is it freezing up because it is not draining the condensation, and then the thermostat in the evap. core is shutting it down? also, are any of the control knobs sloppy, or worn out? jojo

Liz Cheney.... 2024's version of Hillary Clinton... Yippie!!!!! one more (Deplorable) disposable candidate.. 👍 jojo

The Delco 308 39MT 11 tooth starter, is a good alternative. Lighter, and less amp draw.. Typically not rebuildable in some ways, because there is no nose bearing.. I do know that the little relay can fail, but they run about $30.00, and is easy to replace, just keep tabs on the polarity.. I like them.. I try to get my customers to use them instead of the 42 MT.. Of course, the 42 MT and the 50 MT are great starter's.. Just my opinion.. jojo

How 'bout I just read what you post, and soak up the knowledge?? I like these post's because guy's like you teach me something, that will pop into my head later, when I'm on the job.. jojo

"F' I am not smart on the E-6.. but I wanted your opinion about the endplay screws/button's, in the front cover. is it possible that the cam is walking, and causing a different sound? I have one in my shop, and I expect to get back to it and get it done this year, I have the book on setting the endplay,, but was curious about noise, after reading this post.. jojo

To Me.... it is simple.. Yes many countries have their tyrannical govt. But I am an AMERICAN,, I care about our country first, and if we can help other's,, Great.. Hell yeah, help them... But My issue is simple,,,, Our current govt. is doing the best they can to destroy our great country, starting with trying to break the spirit of us,,, The Workers.., and Tell me that because I'm White, I'm the problem, but be right there to take 35% out of my earning's to give it to a D'Bag, that is too sorry to get a job, and because I don't look like him, I have to pay his rent/ food bill/ and every other thing... Really??? 2024, can't come fast enough... God Almighty, I get so pissed off!!! Sorry guy's,,, I know I vent on this thread, please forgive me, jojo

Amen MACKS.. and the throw away money for the Slackers right here in the U.S.A. and don't forget all the freebie's for those that 'WALK' into our southern border, and get 'EVERYTHING THEY NEED'... jojo

be gentle with the EUP wire screws.. they break easy... 2 turns loose is enough to slide the wire off.. light torque when you put them back on.. 5mm 1/4' drive socket.. good luck bud... jojo

visual inspection.. keep it simple.. too many times guys want to grab the laptop, when there may just be a broken wire... visual inspection..... jojo

Yes Sir!!! 'F'... I leaned towards checking valve lash, just from a maintenance stand point. It's free to do, just some labor, and it is also a form of a 'health check'... Of course, he probably has ceramic lifters, so a PROPER valve adjustment is crucial.. 🤔 jojo

OK... so I read this thread from the beginning.. Here I go... Do you have a Jacobs 690 engine brake or Powerleash? Next, Do you know how to run the valve's PROPERLY! on this engine? Including setting bridge lash? I'm talking 'By the book'.. not the 'Cat' way.. for example... jojo

did you use a gauge to check boost pressure?? or just a laptop? 21 seems low.. I would expect 28-31..
