(the "didn't fill" from above are all from AFTER the fix)
I did this a long time ago but I only posted it now because I wanted to make sure the issue is gone. And it is!
I finally found the culprit that's been filling up my damn air filter, making the car run like shite and using oil like diddy.
It's this at #4, the oil separator.
This car hasn't had an oil change in a LONG time before I got it, gunked up the oil separator, clogged it, and the oil started going up instead of back down into the engine. Swapped, and you can see in the photo above how it was immediately fixed after. It's actually pretty easy to remove, it just takes time to take off the airbox first, or at least that's my mechanic told me. How he didn't figure it out when I asked why I had oil in my airbox is beyond me, but whatever.
The whole job is almost as cheap as the oil I had to keep adding.
If you have this issue, you will see oil coming out from this tube that goes in the airbox at #36.
You didn't ask for an auto troubleshooting tip? Well too bad!!!!
Mine's a Golf 4 1.4 petrol AXP by the way. Though, I think many cars have similar things.
If you know a community that could use this info lmk, I'm still trying to figure out lemmy.
Since your car was previously abused (but even if it hasn't I recommend this greatly) start using "Valvoline Restore and Protect" engine oil in it.
It slowly cleans your engine and removed carbon buildup and sludge and frees up piston and oil rings. That brown staying on your oil dipstick will even go away. The shit is magic in a bottle. I started using it three years ago in my Gen 2 Prius that was burning a quart of oil every 1500 miles. Now it burns a quart every 3500 to 4000 miles. My Prius has 290,000 miles on it.
You can check this stuff out on any forums or YouTube videos or all the analysis stuff done by Motor Oil Geek or anywhere else. Not really a negative thing to be found about it. I just buy it from Wal Mart for $30 for 5 quarts. It likely would have eventually even freed up the sludge from your oil separator without you needing to find and replace it.
*Edit: I added some video links in a comment below.
Supposedly, according to the oil geek, you can do the same with cheap oil by reducing your oil change interval.
Not sure if he gets into it in this video, but here he goes into detail about the different brands of oil.

I don't see anywhere in that video where he says that. Do you know about what time in the video he says it? Your linked video doesn't have him testing or talking about Valvoline at all, and he's testing on new engines.
Here are some of his videos he made on restore and protect that are pretty much the opposite of what you are saying. Also, many of his videos on restore and protect may have been after your referenced video, so he may have not even known about it when your linked video was made.

Interesting, thanks! I may not have gotten a clear message from what I watched.
Yea, as far as I know, all motor oils contain cleaning agents. They're packed full of additives. Not sure if I want to introduce a new variable for now. I still have a few engine codes to fix but I appreciate his suggestion.
