By the way you describe this it sounds like a torque limit switch wiring issue to me! if its a mack trans check the wiring to the switch on the range cyl on the upper back of the trans if so equipped! If u have access Vmac software check to see if the torque limit is enabled! Just sayin!

So We received a New Anthem to PDI this Week, So while doing the check over We notice ! Hey!They have removed the Air governor It is no longer on the fire wall were they have been mounted for the last 20 years! Hmmm, went on the the search for the little guy! Yup no where to be found , so we had the parts guy look up the air drier as this seemed to be the only place it could be . Sure enough the governor Is Now built into the Air Drier ! Grrrrreat ! Now when you have issues with compressor build and the like, there is now no cheap way to check anything !We looked at the price for this fine piece of equipment ! Only 1700 dollars !The cartridge A bargain At 300 bucks Never priced the Little governor piece However you can bet It will be Cheap🤑 and easy to find😨! Makes me wonder Why We have to over complicate the simple ! That being said It Likely comes down to captivation or The Fact the air on these newer units need Air to be dri to run the M trans and And the emissions components, this unit may be more efficient in someones mind ! However I can't see the savings in removing a ten dollar valve and 8 feet of plastic tube and replacing it with a 1700 dollar piece of crap that will likely Fail in three years Cause no one can afford the cartridge every year! Again I don't no the specifics on this unit It may be the best thing since sliced bread when dring air, However guess its going to be tested on our next truck sale! Still looking on the internet to see which company is selling this unit. and what Its selling features are compared to the older wabco or bendix units! will post it when I find it! SO I managed to find this unit it is called a SYSTEM SAVER HP AIR DRYER Didn't realize there were others out there, possibly worse. possibly better who knows anyway We will see how resilient it is in a couple of years! Check it out here https://f01.justanswer.com/diesel3153/c9883f39-a857-4660-8748-c053bac5015b_Wabco_dryer_info.pdf 🙄 IF IT AIN'T BROKE FIX IT ANYWAY! 😡

Chances are you have a failed EGR cooler ! usually the mass flow and the cooler will be changed at the same time! is the unit using any coolant?if the cooler looks like it has been replaced and the mass flow wasn't changed the code will remain! Another thing to note these engines were not horribly fuel efficient to start with! A guy Could lighten the situation You would need to make plate for beneath the egr valve an plug the coolant off to the cooler! Down sid is the malfunction light stays lit all the time and you won't know when important shit is going wrong!

Never done this! However Thought about it several times! I think all a guy has to do is cap the oil supply line off(The econovance is spring loaded to the off position anyway) no pressure no advance ! and then tri and pick a suitable timing to to run it at So Say roughly 20 -22 degrees!Just my thoughts on it By no means Fact! Just a guess!

If it had a v8 in it origana1ly chances are the the cat would shoe horn in there R700 Had a longer hood to accommodate the v8 and jober engines!As Terry mentioned R 600 Naw to much messin around!

I like to work them a week or two then recheck em!Just me!Some guys don't retorque! What ever works for ya!

Yup good Job John! were all happy to lend a hand if we can as was stated thats what its all about! Long as the pistons are all installed with front facing front your good to go!

Milkmans suggestion top of the heep! Heres other stuff to try Lock out the interaxle diff See if it changes! = Tires size! Equal ?! Rest your foot Foot on the clutch pedal Listen to see if the noise is still there looking for worn linkage! check the trans tail shaft for tightness ! Ujoints loose ? Rims Are they Steel Buds? = check for cracked rims! Lots of places to look! Last but not least chec the diff plugs see if there is metal in the oil If there is lost of metal on an plug magnet you may have a failing diff! Not uncommon to have crown gear bolts break! Just sayin!

Yup Believe its meant to be high temp !

Big John! This may be off the mark Here but I am going to post it anyway! Early in the evolution of the drive by wire engines, to skirt regulations, manufacturers Were duel Mapping the softwear,If you were light on the throttle it went down the Bulldog bunny trail loafing along ,If you were aggressive with the pedal it would take the Bigdog road map for hills ! Point being ! Im wondering if you have a programing issue or self training issue , And you need to be driving with a more aggressive foot! Just a thought

Also The rod cap is usually stamped with an M2 If its 2 thou under Double check your shells to be sure ! They did this some times rod by rod Worth checking! Use the mack stuff Or Permatex Ultra Gray/black works fine!

The Line is an addon for more oil flow the jake is also fed from the bottom if memory serves! Any way the jake will not be damaged it just won't operate!

Yup ! And no More than 2 thou variance between Liners Under the same Head! Also I your old Liners are at the (low spec 22) I would shim them 4 thou if the engine is 400hp or more ! That being said ! in your case It ran before with no head gasket issues It Will Probably run again fine ! just sayin

Yup Job Done!

In my opinion!No to the bolts if the cam looks good leave it ! Pay close attention to liner height try to achieve 25 or better up to 28 thou!

Yup for sure another place to look! For sure! Bogus sensor or even malfunctioning gauge!

Thats your next step then ! Check the fuel pressure under load! Should have at least 60 psi! After that you need to look into wiring The torque limit switch on the trans will hold back approx 15 psi boost if the switch or wiring is shorted and will not throw a code as the computer doesnt know there is anything wrong it just thinks its in low range!

Nice Find! Governed rpm is just that 2100 will not hurt it! Nice Find ! Likely a 300 hp! trucks built in that era were evolving to drive by wire 350hp and up! I believe 93 was the last year they offered a mech 400! Your rpm and lack of gears indicates its likely 300 maxidyne!

Yup cheers Guys! Stay safe! Hey Bull ! You appear to be drivin Volvo Trash !

Sounds like a fuel delivery issue !Check your oil level if its high the pump may be fubar! Is the primer getting hard or is it spongy if its spongy Fuel pump May be toast! However rule out the stuff given you so far! Also Did u check the ECU Plug for coolant push as directed? Its wurth a check!

Yup for sure seems They have ran off some of the good contributors here over political crap ! we need people to fill the gaps here ! I am currently around this new stuff and see the goins on but don't work on red stuff ( HAPPY NOT TO ) just( most times) a silent observer ! In the shop right now We have a mp8 unit that came in with a miss that started suddenly! down the street from the shop ! The boys pulled the valve cover to check the valve set and one of the guys have the experience of a stuck valve sure enuff, rip the head off valve is bent and the valve next to it has a third of the valve missing! Which We have seen before with MUCH larger implications Broken liners and such! Anyway the point here is It's nice that some of the new guys to the forum put forth their input and experiences Helps everyone learn and may even save some guys Bucks to keep in business ! Quite honestly these new trucks are NOT owner opp Friendly You need All the help you can get if you own one ! Thats where we come in ! So yup! V3, Joey keep up the good work ! If we all contribute we all win in some shape or form! Us old folk Like Glenn , myself and others Will hold up our end as best we can! 😇😅

The origanal E7 was definitely The better of the two But The main upgrade on the eteck came with the powerleash EB much better holding power! !

Leave em alone! Flywheel to crank bolts are 5/8 They are torqued to 180 +/- 5 or so No worries in my mind!

You'll notice that now a days you can find mostly 50/50 antifreeze no mixing required two reasons ! they make more money For sure! How ever water quality is controlled also ! With full strength your at risk of adding in unwanted minerals yada yada! Where I work we wouldn't entertain using the water with antifreeze, Just the Iron content of the water is off the scale We have a big sign on the wall DON'T DRINK THE WATER HERE! That goes for the trucks we repair as well!
