I just completed repairing my turbo charger on my 2007 E320 Bluetech, which had failed catastrophically on a recent trip. The car began to leak oil badly after the failure and I ended up having to trailer it home. I fear that both the intake and exhaust have become badly oil fouled. Upon starting it after the turbo was repaired, after about a 30 minute idle, it began to smoke and began to runaway with itself - turning off the key did not immediately stop it, but it finally died a few seconds later. Not sure how high it revved. I believe the runaway was caused by oil in the intercooler that vaporized. During inspection I noted the electric fan was not completely plugged in and threw an inoperable trouble code .

Started it up the next day and have checked the turbo, and no apparent damage noted.

The question I have is there someway to clean the oil and oil residue out of inlet without dismantling it?
