PCV for M276

Hi Sr, Leigh

Any plans documenting the replacement of PCV valve for M276?

My truck has about 88,000 miles and is a 2015, so probably would be a good idea to replace it.

I think is a bit more complicated than for M272, which I already did for my other car, but for M276 I don't see good tutorials.

What do you think?

Hey Cesar,

Did you change the PCV valve?

If so what did you use?

I was trying to do the same on my M276 W212 and looks pretty complicated.

Thanks.

Hi Cesar,

Sorry for the late reply.

So any symptoms of your truck that look like cause by PCV? I pulled the PCV replace document from WIS for you below.

The original factory pcv is called air oil seporator. It is literally made of paper. When that breaks, you will get a vacuum leak. I got my fixed by a garage mechanic with parts from Ebay. It's time consuming to replace if you have not done it before.
