[QUOTE="6.0 Tech, post: 1552510, member: 23001"] So, I got one kicking my ass here. It’s one of the guys at the shops truck. I built the motor about 5k ago, he went to pass someone on the freeway last Friday and lost all power, pouring smoke out like a 12v with no fuel plate in it. Truck has 190/30s, a stage 1 cam we had laying around, don’t remember if it’s welded or not, Odawg intake, and tunes by tsd. All inputs look ok, ebp is a bit high, but no change with it plugged in or not, fuel pressure sits at 45psi, tried reloading the tune, no change. Swapped ficms, no change, have a run up misfire on 5 and 7, 7 was at -4% on relative compression, had 310 psi on manual, 30% leakage from crankcase and possibly exhaust. No chug from crankcase, but does seem to have some excessive blow by, not sure if he just hasn’t gotten the rings fully seated or not yet, or what’s going on there, but currently not chasing that issue yet. Lol. Truck does have an egr valve, but the cooler is plugged, and according to ids the valve isn’t hung open or anything. Did the bubble test, no issues seen. Swapped bank 1 injectors with stock injectors we had laying around with no change. Truck also has a car, so I disconnected the down pipe, with no change. This thing makes a pile of soot at the tailpipe when running it, acts like it doesn’t have any air. Pulled the cold side cac tube to rule out any cac restriction or anything, no change, but it does sound like a big block now. Finally, pulled the crank sensor, and checked the tone wheel, as my rpm pid was kind of messy, but the truck is running like ****, so I’m not sure what was causing it. Tone wheel felt tight, looked at it with a bore scope, didn’t see any issues while turning it over. I do not have access to an oscilloscope, but what are the chances the cam could’ve come out of time? That’s kinda where I’m stuck at now. Any help is appreciated...
