There is a rumor circulating around the net that the M8 engine is venting the blow-by into the transmission.
Before it gets started here.....
The 2017 M8 engine does Not route the blow-by into the transmission.
Here are a couple of photo's of the tiny stock filter element with the breathers venting the blow-by into the filter element, just like HD has been doing for years.
You can see the hoses coming off the breather bolts to a T connector, then the hose off the T goes into the back of the filter.
The following pics, showing what happens to a Twin Cam...no reason to expect that the M8 piston tops will have any different results.
