If the eng is a 5.0L it is located behind the eng middle to the left I also strongly recommend changing the P.C.V screen located just under the valve you will need a angle pick to remove it If the eng is a 4.6L the valve is located on the RT valve cover.

If there is a PVC valve and hose and filter connected to the air intake, oil could be sucked up from the valve covers when the throttle is applied. perhaps the PVC valve needs to be changed.

The PVC valve will be located in one of the valve covers. The valve covers are on top of the engine on either side. And it will have a hose attached to it which will lead over to the air intake system.

You will find it (the PVC valve) in the same place as you would on a 1995 Lebaron 3.0. I own a 1990 Chrysler lebaron 3.0 v6 and found the PVC valve in the same spot. Look up where to find the PVC valve on a 1995 lebaron 3.0 on this site. Best of luck.

Most PVC valves go in the valve cover of the engine, either in left or right valve cover with vacumn line attached,just pulls out and pushes in for install,usually if pulled out and can shake and rattles its good, if carboned up and does not rattle its bad.
