Should I worry?

[Mr. Detail]

Can anyone give me an opinion since "regent" brought it up about the cleaning or replacing of the PCV system?
I looked at a video yesterday and the guy had the whole front of the engine apart! Taking off the manifold, fuel rail
and a bunch of other stuff. I don't think that job is for me but they said it might be $1,000 to do all of that at a mechanic.

My only experience is with turbo engines, so the NA might be easier (?)

When I replaced mine the first time, it was a chore, yes. But if you have the right tools, new gaskets, and see how easily the intake manifold comes off, it's not so bad. Then you can see and access everything.

If you can do it in a warm garage, with good lighting, buy a couple of extra tools, and you're not in a hurry, you can do it.
I bought a 10mm "crows foot" for that far left manifold nut, but it started to turn so I quit right away - I don't trust them. A 10mm "wobble bit" socket can get in there with an extension. Those nuts shouldn't be that tight. The breather fitting underneath the manifold needs some patience and fiddling to get threaded into the hole upside down.

Others with more experience should chime in for the NA. Have you tried the glove test? Put a rubber glove over the oil filler hole, start it up, see whether it's sucking in (good) or filling up the glove blowing out (PCV problem). Blowing out means too much crankcase pressure, which can push out oil seals or make the oil cap leak under pressure.
