Jeep Grand Cherokee 6-cyl 4.0L. The broken valve is the one that comes off the front of the valve cover and connects over to the air filter housing. I have the replacement (had to order it online) and I can see that the new one should just pop right in, I'm just wondering about getting the old one out? It broke off underneath where it bends so it's gonna be a bitch to get a good grip on it. Reckon I'll just try a pair of vise grips or channel locks and pull it on out, but I was wondering if anybody may have replaced one and have any tips? The one thing I"m worried about is a piece breaking off and falling down inside the valve cover, that would be a PAIN.
