OldDirtyMack Posted December 3, 2022 Author Share Posted December 3, 2022 I’m interested, too Onyx! Excellent info JoeyMack. It is very hard to start. Takes for ever, multiple tries before it finally starts running and then it’s a wall of black soot in your face. It will run, but it’s very rough. Pulled the intake tube off today. Stuff a camera in there and there is definitely something, but it doesn’t appease to be fully restricting the air flow. Have you ever seen a valve break and it be inside the intake?

OldDirtyMack Posted December 3, 2022 Author Share Posted December 3, 2022 @mdixon the air to air is unhooked as well. It should idle like a normal diesel. The other strange part is that there is zero throttle response.

Joey Mack Posted December 3, 2022 Share Posted December 3, 2022 it can happen.. when the piston comes up on the compression stroke, it becomes an air pump.. in this case 15:1 compression, it can certainly blow a chunk of metal into the intake or the exhaust manifold.. jojo Quote Link to comment https://www.bigmacktrucks.com/topic/70813-2004-427-ac-vmaciii-pure-black-soot/page/2/#findComment-517000 Share on other sites More sharing options...
OldDirtyMack Posted December 6, 2022 Author Share Posted December 6, 2022 Well guys, just wanted to update. Found this in the intake. I’m assuming this would cause my excessive black smoke issue? 1 Quote Link to comment https://www.bigmacktrucks.com/topic/70813-2004-427-ac-vmaciii-pure-black-soot/page/2/#findComment-517533 Share on other sites More sharing options...

JoeH Posted December 6, 2022 Share Posted December 6, 2022 I'm guessing that's a valve head?... Quote Link to comment https://www.bigmacktrucks.com/topic/70813-2004-427-ac-vmaciii-pure-black-soot/page/2/#findComment-517577 Share on other sites More sharing options...
