| This is a surprise inspection, and the repair facility (RF) was not contacted prior to my arrival. The RF contact Steve, reports that the vehicle was towed in to their shop, and they have not received any authorization to diagnose or inspect the vehicle. He states they do not know the state of the vehicle, other than it experienced a runaway diesel condition, and there is oil leaking from the turbo. He reports the vehicle was smoldering and smoking when it arrived, and asked me not to run the engine during the inspection.
We cranked the engine to make sure it was not seized, and it took several cranks to get it to start. When the engine started, it ran rough and white smoke came out of the exhaust, so we shut the engine down immediately to avoid any further damage.
Oil is leaking heavily from inside the turbocharger, and is visible inside the turbo housing, around the impeller, and in the intake. The turbo impeller shaft has play, and can be moved approximately 1/16" by hand. There is an excessive amount of oil in the air intake tube and air filter, and air cleaner housing. There is oil all over the top of the engine, and some has slung around the turbo area. There are no visible signs of intermix, overheat, or excessive heat in the engine compartment. There are multiple minor oil leaks and seeps, but the heavy oil leak appears to be coming from inside the turbo itself.
Fault codes P0675 cylinder 5 glow plug circuit/open (current); P0606 ECM/PCM processor (pending); P0675 Cylinder 5 glow plug circuit/open (pending) are present in the system. Please refer to photos for freeze frame data.
Notes: No direct evidence of runaway condition was visible, but the amount of oil present in the turbo and intake indicate it is possible that oil had made it into the intake and caused it to runaway. The white smoke condition could also be caused by faulty ECM/PCM, fuel delivery issues, or EGR cooler/valve failures. The EGR cooler is aftermarket and its condition is unknown. The EGR valve is present. The fault code P0606 indicates a possible issue with the PCM/ECM and requires diagnosis. |
