OldDirtyMack Posted December 2, 2022 Share Posted December 2, 2022 Hello guys! New member here, thanks for any help in advance. I recently purchased a 2004 CH613 from a guy with known issues. It’s very hard to start and once it does, it just bellows out pure black soot and I mean a lot.. like a coal train. I have it at a shop now and we’ve replaced all 6 injectors (2 were stuck open), and 2 pumps. He’s tried running it with and without the turbo hooked up. Changed the fuel filters. Ran the overhead. Nothing seems to make a difference. There is also zero throttle response, but it shows to be working on his laptop via % ratings. He has the newest version software, but it isn’t the VMAC. I’m just trying to get some help and ideas on where to go next. Codes: 5-8 & 5-9 He says he has never seen these codes cause these issues. I have attached a video IMG_3794.MOV Quote Link to comment https://www.bigmacktrucks.com/topic/70813-2004-427-ac-vmaciii-pure-black-soot/ Share on other sites More sharing options...

Onyx610 Posted December 2, 2022 Share Posted December 2, 2022 (edited) Oh my….I believe those codes are egr related. Check charge air system real good? I’m gonna step back on this one as I’m not familiar with the AC engines.

OldDirtyMack Posted December 2, 2022 Author Share Posted December 2, 2022 Air filter system is completely removed. I’m not sure how to reply to each comment separately. Onyx, I’m down to thinking something is stuck inside the intake. Maybe one of those red rags or something. That’s my next step. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/70813-2004-427-ac-vmaciii-pure-black-soot/#findComment-516894 Share on other sites More sharing options...

Onyx610 Posted December 2, 2022 Share Posted December 2, 2022 The rag sucked into the manifold is more common than you think. By the way welcome aboard and there will be more guys to come give you some ideas on this. Lots of really smart dudes on here.

Joey Mack Posted December 2, 2022 Share Posted December 2, 2022 Check the cam sensor and the flywheel sensor. while its running, unplug one of them. if it shuts off, the other one has an issue. the flywheel sensor wires are prone to damage because it gets all the spray off the steer tire.. pull the loom back and gently tug on the wire from the plug up towards the engine as far as you can, its about a foot..

Onyx610 Posted December 2, 2022 Share Posted December 2, 2022 Seems to me as it’s an intake issue. See what others say. Quote Link to comment https://www.bigmacktrucks.com/topic/70813-2004-427-ac-vmaciii-pure-black-soot/#findComment-516898 Share on other sites More sharing options...

I've seen air filters in backwards in Rs cause this.

OldDirtyMack Posted December 2, 2022 Author Share Posted December 2, 2022 It has a new cam sensor, so I will check the flywheel one. Man! Was that rag sucked into the intake? It appears to be quite the chore removing this intake. Thanks so much for the input guys!

Joey Mack Posted December 2, 2022 Share Posted December 2, 2022 yes the rag was left in the engine, I did a ton of work to the engine to try to fix it, and all efforts failed.. When I was at whits end,, I went to pull the heads,, funny thing is... the intake was the last part I had to remove before pulling the heads.. Had I pulled the intake first.. well.... you know.. Next time i will put my 3 foot bore scope in the manifold.. you may want to do the same if this goes further...jojo Quote Link to comment https://www.bigmacktrucks.com/topic/70813-2004-427-ac-vmaciii-pure-black-soot/#findComment-516908 Share on other sites More sharing options...
OldDirtyMack Posted December 2, 2022 Author Share Posted December 2, 2022 You sound just like me. I’ve been asking around if anyone has one of those 3’ scopes. He has a short one.

Onyx610 Posted December 3, 2022 Share Posted December 3, 2022 Look at it this way, people pay a lot of money to make their trucks be able to do that. If you find out what causes it you could be rich!

Onyx610 Posted December 3, 2022 Share Posted December 3, 2022 This one has me interested for sure. Excited to see what you find, hopefully a rag or something dumb and not expensive. In the words of Joey Mack “you got this!” Quote Link to comment https://www.bigmacktrucks.com/topic/70813-2004-427-ac-vmaciii-pure-black-soot/#findComment-516974 Share on other sites More sharing options...

Are you still sucking through the intercooler? Or open intake manifold inlet? 1 Quote Link to comment https://www.bigmacktrucks.com/topic/70813-2004-427-ac-vmaciii-pure-black-soot/#findComment-516986 Share on other sites More sharing options...
Mackpro Posted December 3, 2022 Share Posted December 3, 2022 If it starts but you have to crank on it 8-10 seconds every time then it could be either of the timing sensors. When one goes bad it runs off the the other one but it’s hard to start like it’s a fuel issue. Or someone adjusted the valves wrong. As in when the flywheel pointer was on 1/6 they adjusted cylinder 1 instead of cylinder 6. Seen that happen several times.
