Broken PCV Cap

Broken PCV Cap
I was replacing my brakes and rotors this weekend and just going over the engine bay area to make sure everything looks good. I noticed a little bit of oil residue on the top left corner. I looked a little closer and it appears the PCV cap is broken if that makes sense (I can take a photo if needed). I bout this car a few months ago, but this is the first I noticed the oil. I don't think it's a major leak, but I'd like to get it fixed, but I have a question or two here.
1. Do they make just the replacement caps or do I have to get a new valve cover? Doesn't seem like an overly complicated job, but if I don't have to drop 300+ at the moment, I'd rather not. I read about a Russian company that sells replacements on ebay but I only found the membrane, not the cap itself.
2. Could this cause any driving/performance/oil burn off issues?
I'll see if I can get a photo a little bit later on today when the sun is up.

Post a photo. I want to see it.
Im one of the ones who has done the diaphragm replacement you can see my thread “PCV repair question”
post or PM me a couple photos and I’ll tell you whether or not you can use it still. The diaphragm will probably need replacing too if it’s been leaking there. It does work.

One of what? Oil leak? I doubt all of them are just leaking independently. Probably some single issue causing the pressure problem...probably that PCV thing. It really doesnt look like that cap is broken in any way...I'd try a new diaphragm, clean up the engine, and see if it stops. Hopefully damage isnt too bad to the seals ect and no more oil vapor will escape.

I don’t see where the cap is broken, I think it’s ok, but you probably need a new PCV diaphragm. The oil coming from the tube to the intake is because of the PCV. Can you hear any air hissing or whistling at the valve cover near that cap? A vacuum leak is common there when it fails. Last, try to remove the oil cap while the engine is running. If it’s difficult from vacuum on the cap, you probably have a torn diaphragm.

yeah sorry. Should have posted a better shot. I'll paste one below where I believe it's busted. I agree the other leaks are due to pcv, but there are other spots along the valve cover it looks like it's seeping so I'm just going to bite the bullet and replace the cover. I'm nearing 100k so it's probably good maintenance anyway.

Yeah it was hard to see in that photo. I did the valve cover change this weekend, the cap was cracked, but it was hard to see. There was quite a bit of carbon build up on the membrane as well. The car seems to idle better and while there isn't really any performance gain, it just seems to be driving better. Especially from take off. Maybe I could have just done the membrane but I feel like doing the whole cover was needed. Especially with some oil seeping. Got the job done in about an hour.

It is, mine is like that too. There is a little semi-circular cutout on the front edge, that I at first thought was a missing piece until I looked at a couple others and saw they were the same way
