haha-i just found out i NEED one, and ordered it! we took my car on the highway, hittin 120+ and when we were done, oil was PISSING outta the valve cover! we had the filter connected to the valve cover with a tube like we were supposed to, and with the oil pissing, it went through the filter/turbo/intercooler/engine for like an hour before we realized! we unplugged that tube, and a thick mist of oil shoost out when running, it's nuts! we popped on a little filter from autozone, and it was done in a few minutes! i've figured out a catch can is my only fix, so i just ordered one. let me know how yours goes, and where you put it, maybe do a tech install? thanks man, good luck with it!
