Now you all got me wondering if I need a catch can on my L9H.

Buy it and let it sit in your garage like me., i gitta brandy new mf 12589 in there too...

Of course you do. Are you blackbear tuned? You need that, too.

I Got my blackbear tune a year ago and am loving it, haha. Howeber, I was under the impression that only engines with AFM needed catch cans.

It has to do more with what rocker covers you have, but it still doesn't hurt to have one and stop all of that oil from going into your engine.

ANY engine with a pcv line that comes back around to the intake is going to get blowby.

Oil change! Amsoil full syn and a filter. Cleaned under the hood.
Tires will be rotated this weekend, as I rotate with each oil change.
