You should reroute the hose back to the intake. The PCV system is specifically designed to create a slight negative pressure in the engine crankcase. This negative pressure effectively flushes the crankcase with clean air, efficiently removing all combustion byproducts. Crankcase fumes are both dirty and acidic. Ventilating only during over-pressure will result in the majority of these fumes remaining inside the crankcase. This can lead to faster contamination and dilution of the engine oil. Additionally, it may contribute to the buildup of deposits inside your engine over time.
Thankyou mate, for your very informed reply, I love it! What you say is optimal. In real life, the engine itself is already a pump, and it does push the fumes through the PCV effectively, to the point I can see some coming out of my hood vents when stationary upon cold start in cold weather. I also observed that the can is taking the fumes, so it still is effective without added vacuum from intake. It’s a chep hack, you can always spend 300€ on a full catch can kit, and remember to inspect it frequently, especially during winter for freezing, because that would be a massive issue!
Thanks for the video, I have had this issue with a standard GR , there isn’t much info about this but I knew it wasn’t a problem after all it’s a Toyota.
@AdrianoJamesPiras Another banger Video! I'm learning so much from you. 🙏 I'm wondering what we can do to mitigate this freezing issue. I read that another commenter suggested routing to the intake? Would that technically solve the problem or is the vacuum there insufficient? Is the problem that the hose itself freezes through or just that the catch can contents freezes?
@SasanSB12 thankyou mate! Please share because I really need to surpass the 1000 subscribers threshold, while getting as many watch hours possible. This will hopefully cover for the equipment expenses!! Cheers for any help!
the freezing issue is the liquid deposits that accumulate in the catch can. Just check that they aren’t frozen if you leave the car outside in sub-zero temperatures, by opening the catchcan. The hoses will not freeze because they only contain moist, not full of liquid. The idea is to make sure that intake and outlet of the catchcan aren’t blocked because of ice within the labyrinth

Thankyou for viewing and sharing your thoughts mate!
TY!👍
So there's no need to run the another hose back to the intake tube?
No check engine lights
No problem at all
Is there any problems with using catch cans in cold climates?
Yes, if the residue freezes inside, it will block your pcv outlet and create positive pressure in the upper engine, you really have to be careful!
