Probally settiing injector codes with fmi 8. Basically most of the time just nuciance codes. First of all code is for the unit pumps on right side under the chrome shields. Called injectors in system. They are deigned to run in a certain frequency but as pump wears it goes out of range causing a code. We never worry about the code until the engine starts to have missfire when the light is on. Usually a slight missfire. Most of the time there is difference i the way it runs. Basically every aset engine has these codes logged. The older engines had programming to widen the paramters but yours should be the latest. I would just replace the pump one at a time until gone. When engine runni g and u feel it missi g a bit see what code is active by blinking code and replace that one. Drive again but unfortunately only way to fix is to replace pumps.

Did u get this fixed

I work at a mack dealer and an easy way would be

In the manuals u got with the truck. There is a detailed parts list and picture breakdowns. U can also try emedia on the mack website

I dint remember him having one with an e9. Does yours? Nice truck either way

I think its an old Deitz truck. Cant remember how to pernounce the name but yes i have seen it. He had a bunch of cabovers too. Favorite truck is a superliner

Nothing inherit that are problems. Some things here and there and truely overal are good. The cups problems have been fixed for the most part with the brand new ones. There have been a couple updates even after the stainless cups came out si if ut has the latest dobe it should br good. Trust me keep it at dealer and it will save u time and money no offense to anyone but chasing codes without the proper info leads to problems. Seen lots of money or parts thrown at stuff when it just needs programmed.

Done hundreds of kitS and it helps but dont expect huge performance. Definetley not cam bushings

I run a mack dealer and let me tell u some inside info. These engines are so bad for this and hardware has been updated a few times. This makes tje squeal but sometimes after the turbo mount leaks and does it. If done at dealer one year warranty. Proper mack proceedure is to check straightness between the heads and check for smoothness of heads. They may tell u the heads need to come off to fixed right and keep warranty. This does help but i find they still come back in a year or so. Heavy haul trucks always have problems leaking. Personally i wouldnt take heads off for this and would just reuse hardware. Replace gasketa every so often. Also mack procedure is to replace all the high pressure lines but this is eight hundred bucks. If lines are new style there is no need. Long story on that one.

Can get some. My dad started to restore it but for reasons stopped. When he got it the engine was new and tranny was recent. Kind of a sad situation now as it sits outside. Was never winter driven from new.

London here

Oh my god this sounds like a nightmare. From sounds of it they dont know what they are doing. Did this just need oil cooler from the start. Low iil pressure after rebuiltost likely is wrong size bearngs. Hook manual gauge up to verify sensor is right. Is this a dealer? Hope not.

Cool new here also. From ontario here also

I am a mack mechanic and shop forman at dealer for past 15 years. Joined here for fun and to learn something. I am mack fan and been around product since mid eighties. Maybe i could help a bit on here also. Hope to meet eveyone

Where are u from. I have a 72 R model to sell with rebuilt engine and transmissiion. Project was started and then sat for years. Was my fathers so could get cheap

Grounds are a big thing for this and some were updated where u cut the ground and relocate to the ground circuit breaker on the firewall. Only thing is a tell tale sign the cluster itself is faulty is if customer complains the seatbelt light comes on. Probally doesnt even have seatbelt switches. Probally needs a cluster to fix this.
