Review on Efficient PCV Valve: ACDelco Professional CV936C for Optimal Positive Crank Ventilation by John Butler

It's so important, so easy, so cheap, it's stupid not to do it. Change. Is yours. PCV. Valve. PERIOD. Should I list the many problems this avoids or fixes? Burning oil? Low current? smoking knock? This will fix those issues. Easy change, but a bottleneck. Bonnet open, driver's side, bonnet rear. Follow the hose that leads to the back of the engine. Here is the video that helped me find it. It's a little hard to change. I used some long thin pliers and some 45° locks. Break off the old one by pulling it out. So remember, when you start this job plan to commit.
