Sounds like I may have a leak due to the PCV system clogged, similar to the OP. Thinking I should tackle that. Anyone got any advice or a walk though on how to do that?

Found plugged PCV system on high mileage 02 Yukon while chasing after similar leaks. A plugged crankcase venting system will start leaking oil even in places that not typically under pressure. The 02 original driver side valve cover was caked with carbon in the vented area inside the valve cover. At that time GM had a 3rd design valve cover available with much improved venting and built in PCV valve. Also needed a longer hose. How does the inside of your vent system for the valve cover look?

I took the valve cover to dealership and had a friend run it thru their automotive dishwasher with other parts for 30 minutes. When the tech came to get his parts he told me about the updated valve cover design. The parts department had it in stock and venting design was considerable improved, so I went with the new design. If I can find pictures showing the difference, I will post them.Were you able to get the plugged up valve cover venting again or did you purchase the revised valve cover with the improved venting? If you were able to open up the plugged up one, what was your procedure? Thanks.
So it looks like my 2006 is different.... ugh... no valve. Just a tube that’s part of the vacuum hose.... now what?

I was hoping mine would have a removable pcv to clean ir replace, and maybe that might help slow the oil drips. I guess not so much...Not sure what you're trying to do, Chase? If you're looking for a clog or something, that house just pulls off. Be careful, though, the plastic gets brittle and likes to snap at the connection on the intake.
Why not put a catch can on it?

though my oil leak is not anywhere near as serious as the OPs. It’s on a few drips a day. But it’s annoying. I don’t think a catch can would solve my oil leak.
If there is it doesn’t come separately from the hose. I pulled it off yesterday. I have a new one coming in tomorrow afternoon because the opposite end where it attaches, the plastic is cracked. Thought I had a pic of the whole piece. I’ll have to take a photo tomorrow when I put the new piece on.No, but it would catch the stuff you're suspecting to have gunked up the PCV and caused the pressure that may be contributing to your leak.
Anywho.. there is a "valve" at one end of that hose.
