"This solves overpressure problem of 2.4 Recomended"
Lawrence De La Cruz on 11/29/2025 3:11:56 AM
Comments: This product solves the over pressure problem of the poorly designed ecotec engine. It should prevent premature leaks of the front and main seals saving the owner thousands of $!!! I am also noticing better economy for 80 dollars this is cheap insurance to prevent engine R&R for a blown main seal or completely blown motor. Well Machined, low pressure to activate valve and keeps engine vacuum for proper metering of MAF! I did add a hose clamp to secure the filter to the valve. CFM has made a functional, attractive and well made part that can save the flawed 2.4 from an early death. Well done CFM.

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.
