Hey guys see if you can help me on this one.

The hose next to the PCV valve on my 03 Auto Xterra 4X4 started dripping, about 1 drip for every second. SO I changed the clamp from the OEM Spring type to the screw type. After starting it a couple of times (hoping the cool down and heat up would seal the hose) it still leaks, so this last time I went to adjust the clamp, the alluminum nipple that the hose fits around, just poped out of the manifold. It doesn't look like its held in with anything ....it just looks like it sits there. Before I go and do something drastic like put sealant on the end or GO TO THE DEALERSHIP. I thought I would ask you to take a look!

Thanks!
