I have a lot of what seems to be oil, built up under the passenger side. I can't seem to find where it was coming from. I didn't think it was oil because I wasn't loosing any on the dipstick and it wasn't dripping onto the ground. It just covered everything from the bottom of the manifold all the way to my cv joints and oil pan. I was looking again today and I discovered a hose that wasn't connected to anything, just hanging there. It is at the front corner of my oil pan and it's zip tied to another smaller hose that has a foam sheath around it. I followed them both back up to a small box underneath the intake that had a hose that went and T'd off next to the waste gate of the turbo. These are the best pics I could get. Any help would be great, thank you.

That's your pcv..

It's normal to have some oil coming out like that. How many miles?

145,000. It had 100k a year and a half ago when I bought it from the original owner. He was an old grandpa. I ran a ppe xcelerator for a few months when i got it, but I took it off. Now it's bone stock besides a ppe boost increase valve, lml drivers side manifold, turbo intake horn, S&B Intake, 5 inch straight exhaust

Look above that broken hose, you may see what looks like a pot with a nipple on the bottom thru all that oil. That should be where that little hose connects.

Have you checked your oil level lately? In some cases fuel will fill the crankcase and push out the PCV vent.
Although it just looks like oil, bit its worth checking.

Oil level is good. I change it religiously every 5k. Just changed it 2 weeks ago. But I've seen this oil down there for the last 20k miles and parked in the exact same spot with no oil on the driveway.

I'm getting oil and white smoke coming out of the vent tube too. I just bought the truck and this is its only problem. It's enough smoke I can see it behind me driving and a cloud when I'm stopped. Does the pcv catch need replaced or does that tube connect somewhere?
