Crank case ventilation
I have a 1995 5.8 I’m converting to carb. It has a hose connector on the oil fill stand pipe. Can I weld this shut and just run the POV from the other valve cover to the air cleaner? It has a plastic screw in cap with no vent for the oil fill cap.

I'm sure it's an Issue in California where "No es bueno" is a Pollution control thing but oil Contamination is a BS thing IF you change it as required. PCV was not designed to save oil life it was designed as Pollution Control and as a matter of fact is probably more harmful to the oil than the Road Draft unless you can show Tech Data that proves otherwise... Personally I've never seen it....
BUT I do understand the need for PCV in today's world so I'm not really arguing with you
I really didn't mean for my last post to be commented on it was just in jest to the one I Quoted.
EDIT: when Rings are worn out ... PCV or Road Draft it don't matter the oil will have a shorter life.........

All engines have blow-by, even new ones, starting from the first moment they're started. They're partially combusted air/fuel gasses. If they're not extracted, they will mix with and contaminate the oil, unless you change the oil after each time you run the engine. But most of us change our oil at 5000-7500 miles, so that's a lot of collection of blow-by gasses if they're not being extracted. It also happens to helps reduce air pollution, and that's an additional benefit no matter what state you're in.
A BAD PCV valve can cause excessive oil consumption.
If the draft tubes of your marine engines are just dumping into the water, they're polluting the water.

Fully combusted exhaust in theory should be just carbonated water, which can be acidic. Partially combusted fuel contains HC and CO, which are more toxic. Real exhaust is somewhere in between, but hopefully toward the former.

generally the marine systems are vented to atmosphere and not direct in the water...
But even worse is the 2 Cycle engines running 80:1 mix just to **** folks off ... gives new meaning to "Smoke on the Water"
catch cans are handy too of Course.

I had two cars that I converted from road draft (what I used to call "Stink Tube") to PCV. One was a 1964 Ford, the other was a 1970(!) Toyota.
I got fed up with the Toyota's road draft setup because when I would be stopped at a traffic light, blue smoke would start to ooze out from the hood, eventually enveloping the car in stinky blowby. I picked up a PCV setup from a junkyard from the same engine family, which improved things tremendously.
The 260 Ford was also converted with factory parts, but was less impressive an improvement. But it was a pretty decent engine with a stock 4V intake and dual exhaust.
