also a service campaign to replace the crankcase breather hoses.
AND yes that engine does have a TRUE PCV valve that must close under boost OR oil will be pressured into the engine & also into the air intake area & damage the air mass sensor.

Hey Doc,
I do have oil in the harness (by the front cam magnets). I have ordered new parts to replace those and they should be enroute.
There was a recall to replace a hose that sits under the supercharger I believe. That recall was done as well.
The 3rd bulletin in regards to burnt valves, is that an actual recall? From my search it seems like the issues exist but there was never an official MB recall - but more like a bulletin to alert folks that such a problem has been found.
Finally, is there a way to test the PCV valve? How hard is it to access? I'm really not familiar with this vehicle honestly so I don't know how everything buttons together. I've read up on the issues with the MAF getting oil on it. When I install the new cam sensor seals and harness I will tear down the airbox and MAF and clean it. Just from removing the filter at least, I don't see it being covered in oil.
Any tips on what I should look for would be great Doc.
Thanks.
