#1
Hi,after alot of searching found the location of pcv under map sensor but when I removed old one did not find the spring that is shown in photo that is supposed to be on top of pcv Question is this supposed to have one or not and if so what is the purpose for it. Thanks Bill[img]uploads/lucky6025/pcv_valve_picture_1996_3.8_buick.jpg[/img]
