Artful dodger

Worked last night or tried out of the blue I get a bad vibration at 45. 50 mile an hour again first time this happens carrier bearing cradle was loose 2 bolts that hold it to the frame.. I carry an entire tool box full another box with nuts and bolts a 6 ft cheater bar 12 ton bottle jack 3/4 inch drive ratchet 16 inch ext and correct sockets and a few air tools in this truck everyday. Anyway u joints bout to come apart I limped it home about 3 this morning that’s what we are doin today any neat tricks to make changing these suck less? lol

Yes it’s seeping and the what I believe to be the brake valve is leaking out the diaphragm or rubber cover on the front of the valve. In my infinite wisdom thought I had that fixed I had a brake can on the front pusher blowing air out the top first I just cut the brake line (it was old) pinched it off thought that would do it well it did not. In my experience which compared to yall isn’t much especially with Mack if valve is leaking most of the time it’s something down the line that’s bad not the valve but I’ve yet to find it. Guys I just wana tell you how much u all are appreciated fjh joeymack the hienz Mackpro you guys have hung in there with me.. life throws all kinds of curveballs and it’s thrown me a good one but I still believe that there are good people out there that are willing to help you without any desire for anything in return.. sometimes a guy doesn’t need a hand out just somebody to help him up hats off to you fellas thanks

I asked shop that ? After the oil leak started and was told that the studs went no where near an oil or water tube but in shops defense first time they had ever heard of this engine let alone worked on one I was afraid to do the manifold and the studs at home because I always snap one off and spend half a day getting it out . Also the air valve that’s bolted to the firewall up high on drivers side like right by the vgt valve is there a specific name for it it’s leaking out the diagram on the face of it

Good morning fellas well I haven’t been to bed yet but heard phone going off so thought I’d see . I do believe turbo is stroking correctly and maybe fellas I’m just expecting more out of this thing than it’s got picking up a boost pressure gauge today after a nap and gona see what that tells us. 65 miles per hr 14 on rpm . Just put new radiator on it EGR is capped off 6 new epu new ex manifold new compressor oil pressure at idle around 30 down the rd 60 engine temp rarely hits 200 even on hot days generally stays in the edge of blue into green a bit. I’m leaking oil after the epus where put in can’t figure out where it’s coming from exactly pressure washing it this afternoon and hopefully figure it out. My opinion this is a pretty cool ole truck I’m gona try to save it I wish I knew or could find out without having to pay Mack dealer I’m sure 1000s to tell me how it’s programmed oh and yes throws egr fault code all the time think I answered what can think of I sure appreciate everybody

No boost gauge fjh sorry for delays in response dads getting worse and more a more time being spent with him . So honestly this damn truck on the low side will pull the house down. It’s up hill that causes it to just fall flat and I’m not talking 7% grades I’m not climbing whistler im talking just run of the mill up downs it just doesn’t like them. I really like this ole truck and just want it to do what I think it’s capable of doin and I’ve got a lot of blood sweat money and tears in it!! If I could find someone to tell me how it’s programmed I think that would be a start I’ve asked around nobody seems to know and the dealership hasn’t been much help since it’s deleted

Sorry fjh been putting out other fires yes I have been watching and checking the wastegate position and it’s actually going back to the same place everytime now I’m not sure if having all the cylinders firing correctly may have changed things or the exhaust manifold being fixed idk the answer to that. And I may be reading the truck all wrong. This may very well be all this 427 has my theory was that ten speed transmission suck and the gears seem to be relatively tall in 10 I can run 85 90 mile an hr empty tried it once just to see if it would still only at about 16 on the rpm’s but when u start up a hill and obviously that overdrive gear isn’t gona pull much but I’ll get down to 7 pretty quick my thoughts where the half step drop on the thumb splitter would allow less space keep rpms up and it would continue to pull without dropping to 35 45 miles an hr and I’m not running super heavy 18 ton at most and grade makes a diff to just seems like it should have a bit more I get my ass handed to me by 350 hp trucks. All the time .. also since new epu have been put in there’s an oil leak turbo side left to right it’s seems to be at first 2 epus too of brand new compressor I can’t tell where it’s for sure coming from I’ve washed it real good and tried to see but I just can’t tell

Joe I figured you would find this I’m hunting anybody with a program or that’s ever set one of these up. into stupid to quit I guess and I’d like to keep a Mack engine in this. I think a 13 speed is where I’ll have to start maybe being able to split the top will help this just falls on its face between gears

So I wana start with thanks gotten some incredible help thru this forum I need more . As a few of the fellas on here know I bought Mack having no idea that they where so diff than the rest of the field.. thought I was getting an e7 per the seller nope 427 asset ac.. hooking it up to computer that’s available it pushing 426 hp it has all new epus new compressor new pulleys new steering box new radiator new fuel lines newer suspension on the truck still Hendrickson air ride tho . I driven owned and repaired trucks most my life so I’m not green there except for this motor .. it was deleted exhaust to egr plugged coolant still runnin thru egr cooler I’ve driven a lot 400 hp trucks and this one doesn’t seem to have the power those do.. is it a Mack thing ? rearends and tranny maybe think it came with rearends and tranny from factory ??

How do I find out what program was used on deletion or is there a tuner program for these engines

Chn613

Appreciate yall id sell this damn thing if I wouldn’t feel guilty about the headache it’s gona cause somebody else I just don’t think I could sleep at night 😑

Looking into tank today as well Joe

Hey guys so coolant leak is back ordering radiator today now it’s pooling up in the fan shroud not sure how yet that it’s getting in there like that only reason I say that is it sits higher than the bottom of the radiator I can find any coolant hoses that are leaking stop leak worked for a few days I did notice one side of the radiator on the bottom pass side will move back and forth a bit as where the other side does not wondering if it’s Jared the crimps loose or rubbed a small hole this trucks just been a nightmare lol

Yeah, for sure sucks

Just part of the stuff wrong

Y

Oh shit ya its alot smaller that that there’s a metal tube in place of the missing hose can the egr cooler plug up gona send you some pics of yet another shit show with this motor and I don’t believe it’s pushing coolant I’ve blown head gaskets and cracked heads before no white smoke maybe a puff on startup and not overheating

Gona replace radiator eventually I was on the road when this happened and I had some JB Weld so I scraped everything off cleaned it up good and JB weld the nipple back in or the piece of pipe they stuck in it and now it’s not leaking there at all fjh said something about the EGR cooler. What would that be? I wonder

Well I thought so clamps weren’t very tight but there was coolant on the y hose this morning I can smell antifreeze when truck is runnin now on top of the radiator there the overflow tube that runs back to reservoir some idiot broke off the nipple and instead of replacing radiator which I get it shits expensive they used gasket sealer and super glue stuck a pc of pipe in the hole glued it and put hose back on it was leaking there I fixed that funny thing is truck has never overheated and only 1 time did it just piss antifreeze so I’m lost

And of course it’s missing now how do I explain the coolant disappearing

Not sure what u mean cut it’s a y hose one to oil cooler the other to elephant tube

Fellas where is this screen again am in wrong place

Thank you guys fjh JoeyM again you come to help thank you Mack pro thank you I’ve been dealing with my dad but now ready to run this down so bottom of the radiator to the oil cooler let’s see what happens
