Changed PCV valve
I just changed the air filter and PCV on a new TLS that I picked up 2 wks ago
Air filter is super dirty.
The PCV came out very oily like it was dipped in oil. There is actually a bit of oil dripping from the hole after the PCV came out. Is this normal. I changed PCV on other hondas but never seen them that oily. Stucked my pinky in the hole to clean out as much oil as I can before installing the new pvc into the hole. How did your old PCV look like when you guys change it? Is this normal? I have a feeling the new one is already covered with a bit of oil after it is installed.

I am in Canada, car has 90k and I purchased from an Acura dealership. This car has all service records from Acura for every service since the beginning. So is using dealer engine oil.

I'm actually replacing my pcv soon (ordered from rockauto). Will let you know what I find.
I'm sure it hasn't been changed because when I went to order it for the RDX, the stealership parts guy said that's a lifetime part doesn't need to be replaced (chyeaaa right!) and they were back ordered for the RDX, had to grab it from the US.
I'm also in Canada, and the vehicle I purchased is from dealership and has had all its oil changes there. I believe in Canada Honda uses Petro Canada oil which is not bad.

They usually have some oil. Do you know the brand? If you know the brand, look up the NOACK value and it's likely pretty high.
I suggest switching to an oil with a low NOACK value if it bothers you. This has many more benefits than just oil in the PCV system.
There are other reasons that you could have a lot of oil in the PCV system but the J32 is so solid they probably don't need to be mentioned.
For what it's worth, using Redline 30wt, it's almost scary dry.

I will upload a pic to show you guys soon.
Planning to do a seafoam before my next oil change.
Do you think I can buy the spray seaform deep creep and spray some into that pcv hole?
I think with the angle of the pcv, liquid would just drain back out.

Internal combustion inevitably involves a small but continual amount of blow-by, which is when some of the gases from the combustion leak past the piston rings (that is, blow by them) to end up inside the crankcase. The gases could be vented through a simple hole or tube directly to the atmosphere, or they could "find their own way out" past baffles or past the oil seals of shafts or the gaskets of bolted joints. This is not a problem from a mechanical engineering viewpoint alone; but from other viewpoints, such as cleanliness for the user and environmental protection, such simple ventilation methods are not enough; escape of oil and gases must be prevented via a closed system that routes the escaping gases to the engine's intake stream and allows fresh air to come in.

hummm interesting I was under the impression the PCV valve was the black piece located horizontally near the dipstick. Atleast thats what im pretty sure I saw on the parts diagram. Is it different or something for the 3.2? I have a 3.5 Type S and I thought it was the black piece thats held in with one bolt kind of near the dipstick. Oil also dripped out a little bit when I removed that piece to inspect it. Perfectly normal.

I took a look at my PCV and it is covered in oil. I tried to get a replacement from autozone but their database had the wrong part.
Here's the link to a 3rd part PCV from rock auto for ~$20

PCV is just a simple one way check valve. If it's frozen open, order one and replace at your leizure. If it's frozen shut, get another immediately and gut/remove the old one if it takes too long for a new one. One disclaimer though, I've never done it with the TL but there's a small chance gutting it can raise the idle speed.

Do these typically get clogged on the 3.5 tl type s? Read above that one dealer said it is supposed to last the life of the vehicle. I am at around 76k was thinking about throwing a new one in.
Just a heads up the 3.2 and 3.5 have the same PCV part numbers

It's stupid cheap, just throw a new one on and call it a day. Takes 2 minutes to take on and off and one of those minutes is running to the fridge to grab a beer once you're done

I would buy from dealer it's only $30
I always change it once I buy a car because chances are previous owner had NO clue. I didn't either but it was a common sludge causer on my previous toyota.
I would change it every 3 or 4 years. I'm due for the next one soon.
