Well I've heard that the standard PCV system can leak boost when boost levels are increased, and being made of plastic, they can just wear out over time, so I've ordered the FTP PCV V2 Kit off Ebay,
https://www.ebay.com/itm/New-FTP-SG84...
and decided to try and test it with my tire inflator, I brought a cheap replacement also, so I tested all 3, including the original one off the engine.
I did have to put on some thread tape on the new FTP PCV but I now know it can hold 30psi of pressure and not leak.

It's the first video like this that I've done and I may have made some mistakes, but I hope this helps!

Thanks for watching!
