Black smoke and blowby Cummins 5.9

“We got the Blowby Pack to see if it would help our 2003 Dodge Cummins 5.9 24 valve engine. It’s got 300,000 miles on it and it’s been having some pretty bad blowby happening, as well as a lot of black exhaust smoke. We used  the oil flush treatment, and have been running the FTC Decarbonizer in the fuel. We’ve only done just over 100 miles and already we’re seeing an improvement. The black exhaust smoke has completely stopped, it’s running so much smoother, power feels to be up from before, and the blowby seems to be starting to slow down. I think that may take a bit more time yet. I honestly thought the engine was in really bad shape and was heading for a full rebuild – $8000. We’re really happy with the results. These products seem to be doing as you say they will. We’ll get some more soon for our daughter’s 2003 Ford Powermax. Thanks, a great product.”
