Re: Oil drip from bottom of turbo

"Mine does that too. I replaced the turbo outlet rubber hose, that helped, but leaking out of the plastic pipe from the air filter to turbo. The oil is from the pcv system, and the plastic hose can't fully seal, so oil slowly leaks out that pools up at the end of the pipe. I have confirmed this, I removed my pcv hose from the ptc nipple, and vented to atmosphere for a few months, my leak stopped, re connected it, and it came right back. I chalk it up to increased blowby from older engine causing oil separator to not work as well."

Yes, that's it alright. Thanks for the explanation. It is a little damp around the ptc nipple as well. Next time I do PCV will "upgrade" to larger hoses, which will fix this? Still passes glove test nicely, though.
