I've been around some time on cars in general and now new to Honda. Absolutely love my 2020 accord EX-L. I just got to digging on these forums and figuring out the PCV system to install a catch can on the car. I already installed the PRL intake on the car (at ~250 miles) and already noticed oil film on the inlet side to the turbo at the hard plastic inlet pipe. In looking up the mishimoto catch can, the installation instructions have you installing it at the back of the engine, intake manifold and valve cover connection, which they provide a check valve in their kit. PRE-installation of this check valve, when the car goes into boost doesn't this rear existing line leak air into the PCV system and at the front of the engine the turbo sucking on the PCV pulls the vacuum.
So here is what I'm getting at. Why from the factory is there a line at the intake manifold (boost pressure) that runs to the valve cover? Or did I miss something and there is more I don't see.
There definitely needs to be a catch can at the front of the engine at the intake connection as I can already see oil film albeit very little but it is there. Also knowing catch can kits currently install at rear it seems a multi point can with check valves properly installed may work and be able to use 1 can. Still thinking on this.
