Default Acceptable blowby for stock engine driven aggressively

I recently put in a dual catch can, 2001 vvt motor and took it for speedy drive. No hard corners, mostly straight highway, but lots of full throttle for about 30 minutes.

Is this normal, or excessive?

Nothing in the exhaust side, but this is the from the intake side catch can...

It was when I did the timing belt job two years ago. Is this worth taking it off to check?

Is it too much to ask a 80whp car at 6000ft to sustain 110mph up a hill? Apparently yes lol!

There is this section of HWY 12 that Ed and I drove through, goes over 11000ft, and I'm not exaggerating, I couldn't even keep 55mph.

Yes. I want so bad. I have been in an arduous boost withdrawal since 18psi at redline with my 2002 wrx. That was in 2007!!! :((((((((((

In related news, if anyone wants to buy me a TDR c30-84 rotrex kit with intercooler, or TSE EFR 6258 complete kit (when its finally available) I will love you forever and ever.

Wait, wouldn't boost make this problem way worse?

So I can take the valve cover off and check the baffling, or just rebuild the engine with not shitty rings? Are those my two options?

Wouldn't compression and leakdown tests be the next step?

do a compression and leakdown test. Are you still using the PCV valve? how is the catch can setup? Milage seems to be low for any real blowby. Makes me think it is something else in the setup. I know we can see plenty of "blow-by" if there is something wrong inside the valve cover.
