Having problems with your 1990 Buick Reatta ?
Changing PCV valve
\015 Where is the PCV Valve located on my 1990 Buick Reatta 3.8 V6??\015
You pcv valve should be located on the top or around the intake on top of the engine. It is covered by a little pcv valve rubber hose...it is easy to identify because it is similar to a radiator hose but a lot smaller...no where near the size of a radiator hose...but when located, the pcv valve just pulls out and to check for it being bad, shake it and it should sound like something loose inside the pcv valve (thats a good pcv valve) but what they look like, they should be a silver looking color with a small little neck on it
