HELP! - I think my VGT is sticking...
Hi everyone....haven't been on in a while.
I've got a 2005 6.0 with a gauges, SCT Xcal3 with Eric's tunes and a 4" exhaust. After hard accelerating and you let off or the truck shifts and RPM's decrease, the turbo will not build boost when you step back on the throttle. It will have a deep throaty sound and sometimes black smoke out the tailpipe. Also when this happens the exhaust temps start going up. If you play with the accelerator or slow the truck down and get back in the throttle, the turbo will act normal and off you go, like normal. I also have a P005 code, saying some fuel check valve or something..........
My gut feeling is that the vanes are sticking in the turbo, but I could be all wrong. I took the intake tube off tonight and checked the turbo shaft, and all seems to be well. Impeller looks good and minimal end play.
Do you think I'm right? I've got to get her fixed tomorrow cause I'm leaving on a trip Wednesday pulling my camper to Ohio.
Thanks in advance for the help.
