Peterbilt or Caterpillar forums
Was wondering if there was such a forum or a go to source who knows their Acert chit. I've got a 2007 C-15 that may have lost the turbo. Doug on the forum here talked with me a bit about what may be going on with my rig and yesterday I think she finally let loose but I need to present a good argument to my office or better explain it to a dealership flunky.
Maybe someone here may have some ideas so I'll explain a little
I had been gettin the cel out of nowhere and when so it would cut the truck back to 30psi or less of boost and just be flat pedaled. I could clear it by shuttin down the engine and the code will clear and I'll get full power back. The dealer claims that a wiring harness up in the rocker box could be the problem and or the injectors themselves are at fault. He also mentioned some other sensor I can't think of right now. At any rate the dill weeds at the Rockford dealer never went under my valve covers to inspect even though I was charged. Also he brought up a theory very simaliar to the 6.0 psd "stiction" symptoms because I was extremely over on my drop interval for the oil. Here I am 4,000 miles later and I get the light back and the old symptoms. Doug was explaining to me about these steel inserts that fit in the exhaust ports of the head to align the gasket during assembly and to isolate the gasket from being burned out, he said by 150k miles they can dis lodge and go through the exducer like a fruit on a blender wiping out the turbine. Now his explanation makes sense to me and can relate to it because with each shift as I build boost at wfo I hear debris rattlin around in the elbows where my exhaust meets the muffler. Yesterday I had to remain at wot just to maintain 55mph on flatland yesterday, I was runnin full boost but she had no umph. Today I could barely make it to the wind farm to deliver because she's all gone.
So that's my life story, maybe someone could offer some insight from my post. Thanks
