Where is the PCV valve in your 1990 Chevy corsica- I have looked everywhere for it- found two things which you thought were it but was not- one had a screw cap on the valve cover and the other came?

Answer PCV VALVE SHOULD BE LOCATED ON THE BACK OF YOUR ENGINE IN THE VALVE COVER, IF IT'S A V-6. A WONDERFUL SOURCE OF INFO FOR YOUR CAR IS A WEB SITE CALLED ALLDATA.COM. IT IS AN ONLINE TECH MANUAL FOR ANY VEHICLE YOU ENTER, IT COST $14.95 A YEAR BUT WELL WORTH IT, I HAVE MY CORSICA LISTED AND IT'S VERY VALUABLE T HEMPLE On 89 4 cyl vacuum hose goes to a unit that screws into valve cover.

Pcv inside of hole in valve cover. Have to remove pcv valve by putting needle nose pliars into hole in valve cover and pulling out pcv. In addition to new pcv you may need new O-ring.

This info was hard to find as it was in a short paragraph in a repair manual. Maybe V-6 is similar. When you unscrew unit you cannot see pcv unless you direct a flashlight into hole in valve cover-easier to see at night.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
