Oil leaking out of intake...

Its been awhile, hello errbody, got a few questions for ya's. I removed my cone filter when I noticed that I had oil leaking out of the tube. It has also been leaking out of the pvc tube on the top of the valve cover. (G60)
I fear ring job (208k on the motor). However before I went tumbling down the rabbit hole, I wanted to get you guy's opinion. Its a 91 Eco, it does have the baffle. Could this be a PVC issue? Is there anything I should look at before considering a light rebuild? It starts fine, runs fine, burns a little oil, and overall runs great. Is there something I could do..like maybe a catch can or something to keep the oil at bay?
Thanks!
Edit: Something else I wanted to add. It is also leaking out of the little nipple that usually runs to the TD pumps. I used it to feed my boost gauge. It has clogged up the tube and consequently my boost gauge doesnt work.

I would run a catch can that has an external level dealio. So that you can then effectively record data and how much oil is being shot out of the PVC.. I have one coming in the mail for just this EXACT issue with my M-TDI AHU (317k miles).
I figure the PCV is really only good for an engine with litle to no blow-by.. because once there is some the oil just goes along for the ride and the PCV is pretty much a straight shot back to the intake.. and because you run a cone (like me), i is likely dirty from belt throw-off (like mine does) and therefore is making a slight vacuum in the intake tube (like mine was). Making it even more perfect for the oil to not leave suspension and make its way to the intake tract.
Get a catch can, if it runs fine you likely just need an upgraded PCV setup, like a catch can
. Lots of cars run them, I think most should to ensure NO oil has the possibility to get back in the intake.
I took my turbo intake hose off, and am extremely surprised I do not have a run away every time I start the car...... LMAO SO MUCH OIL IN THERE!

I'd at least test the compression.
I can't get wunderground.com to access the WX at Aplha Quadrant Sector 001, so I can't say if cold temps will ground you... but when my rig with 208,000mi got bad blowby, it wasn't long before it wouldn't start in the cold (even with a block heater).

So im going with a catch can, found some DIY's and I have a pretty cool aluminum thermos I am gonna use. My questions is, should I delete the hockey puck all together? Just run my hose directly from the little rubber grommet the hockey puck plugs in to right to the catch can?

No, still run the puck, and replace it while you are there. It'll keep what little oil it saves in the engine.
Also, considered a Provent? Plumb into the block off plate, run a check valve, and you won't ever have to drain it. The thermos idea is a great DIY solution, which you can do the check valve drain mod on also. Just don't forget to loosely pack some oil catching media in it.

Ill take some pics of the the thermos and where I think I am gonna place it all. I was gonna go with some "Chore boy" copper pots and pan scrubber as the collection media. Its nice and loose and I wont fear it breaking down and going into the turbo. I like the idea of the check valve, but the thermos has a pretty cool pouring system that will make draining it a snap.
On a Mk2, any recommendations for mounting? I have eyeballed a spot in the back of the engine dept Im gonna go snap a few pics, and show ya where I am thinking of mounting it. Get some feed back.

The can. Going to mount it upside down with the inlet drilled center. Outlet off to the side.
Push button open and close.
Thinking of using a large hose clamp to mount it to that C clamp looking thing.

Whaddya think?

I think mine was $6 including the hose, but it's not the greatest materials.

i think running it mounted next to the exhaust is the worst idea ive ever seen..
there is enough heat there to really burn stuff up..
i dont think that right next to a HOT exhaust system, is the best place to mount an oil recovery can..
i would mount it up towards the front of the engine. there is a block off plate on the front of the engine that you can drill and tap, install a fitting, and then BAM, you have a spot to drain the oil back into your engine, out of the catch can..
when i installed my can, i ran the hockey puck on the head, and the outlet of the hockey puck to the top of the catch can.. then i ran another line from the BOTTOM of the catch can, to the port on the front of the block, next to the oil filter flange.. then i ran the outlet of the catch can to the atmosphere..
used clear tygon tubing for all of it.. the CCV inlet, and oil outlet hose were both BLACK.. the CCV outlet hose tho, was completely clear for the longest time.. never had oil drip from my breather hose after the addition of the small catch can..
also, its said you NEED a check valve in the drain line, but i never had one, and it still worked fine.. i never drive my car long enough for the catch can to fill clear up, before shutting the engine off, and having all the oil drain back to the crank case..

How does water get through that hose when it is kinked like that?
