Default Blowby

Hello all. Just a quick question... I don't know if the amount of blowby smoke I get out of the dipstick is 'normal' or not. To me it seems excessive. I made a small video, if anybody cares to comment.


And while we're at it.. I made another video where you can hopefully hear the strange hissing noise around the throttle body I just noticed. Is that normal as well or do I have a leak somewhere ?

Well if anybody searches for blowby and reads this thread.. the fix was the PCV system. The "T" in the back of the intake was broken, allowing blowby gases to vent out (into my cabin air system) and this is why I was seeing so much blowby out of the dispstick. Because now that I fixed the PCV system, there's no more blowby out of the dipstick at all.
