In todays video I share an Interesting Diagnosis of a 2014 Mercedes-Benz C63 AMG that had a multiple Cylinder misfire. What started as a routine misfire diag quickly escalated to us having to tear into the vehicles valve-train as excessive lifter noise was discovered. What we found was a hole in one of the intake lifters on the number 8 cylinder, along with excess wear on the other lifters. This is a known weak point on most M156 engines and often leads to a loud valve train.
I want to apologize for talking a lot in the video, I initially recorded more in depth clips of the diagnosing process but the audio was terrible so I just made a recap of our diagnosis. Hope you enjoy and I will be sure to improve in the future videos to come.
