It is a shame what used to take minutes to do now takes 40 minutes. They don't teach common sense anymore.
To be fair the part is more than just a vent for the crankcase. It also condenses any oil vapor and returns it back the the engine via the large hole in the top left corner of the separator foot print right next to plug number 4. I guess it could be done without taking the 2 coils off but it would require a longer triple square than I have and that may have saved some time but I wasn't rushing and it was my first time doing it. Next time I'm sure I could do it in probably half the time.
