"Good quality"

Comments: GMC Terrain is known for clogged pcv valves blowing out main seals. Ive had this a year and no issues. Have cleaned it several times with brake cleaner. Everything is holding up fantastic. I dont forsee ever having to replace it.
"Saves the equinox 2.4 engine from horrible PCV pressure"

Comments: This saves the 2.4 Ecotec engine from the crappy PCV design. Will save you thousands in blown rear main seal and pays for itself in added fuel economy. My only regret is that I did get one of these when I bought the car new.
