Didn’t like the factory pcv system, made a better one. Plenty of fuel now too

Innovative solution!

Can you explain what you see ?
A picture I know is a thousand words but I don't see what it's about ?

The PVC system, I’m thinking the elbow and hose connected to the top of the air filter.

Yeah that's filtered air that would be on the inlet of the crankcase.
How does that solve a PCV problem?
I'm guessing what ever was done solves coking on the back of the intake valves.
There is an aftermarket manifold on it and that has provisions for an external PCV system.

Please explain what PCV has to do with fuelling.

I see an aftermarket intake manifold, with port injection added. A line with a check valve, connected to the port on the head, between intake ports 2 and 3(where the original PCV valve was positioned), can't see where the other end is connected. A braided stainless hose connected to where the oil filler cap used to be, can't see the other end. Aftermarket charge piping. Aftermarket warm air intake.

It looks like the bypass solenoid has been relocated to the top of the valve cover, one of the vaccum lines seems to be missing.

Something different on the HPFP, a braided stainless line, and something on top of it, looks adjustable.

That was my next question.
You know what gets me ? The person that started this hasn't come back to explain the fixes.

Running NGK colder plugs, there’s a possibility of a random miss.

Cat Man HHR

Why ?
Proof please.
