Well I spoke with Kurt Urban (godfather of LS engines). We have worked together twice in the past. He said run a breather can. but keep some kind of PCV hooked up. So I added a PCV valve from the intake to the valley cover.

Some people have boost pressure at their intake and I have been told the pcv valve will fail at higher boost levels and then allow pressurized air from the intake into the valley.

You will also get a fair amount of oil into your intake from that hose. I don't want any oil getting into my charge air.

Understandable. I have noticed a serious amount of fumes running the breather can. It is so bad I am going to vent the can outside the engine bay. These engine bays are sealed up fairly well and the fumes are coming in through the vents.

I build a custom catch can/breather and water resivor/overflow tank. Won't work with procharger cars (if I can find a local with a procharger i can design and build one that will work with procharger)

for vents,

I pull the valve covers off and press out the pressed in fittings, i then drill out slightly and tap with 1/2" npt to use a nice an fitting on -10. Both valve covers vented and the pcv vented to the tank. The ugly plastic oil seperator behind the water pump I pull out and i take the drain tube out of the oil pan, I then cut it down and weld it and re install it just to keep the pan sealed off.

Heater lines can easily be ran back but I live in Houston Tx and don't need any of that stuff lmao. I will add them back in later it starts getting foggy windshields and get tired of wiping them down with a towel I'm sure.

NO Professional Motorsports "vents" with breathers as they know better than to sacrifice the engine. Also, venting results in ring flutter and compounds blow-by. Anyone venting could be sacrificing the durability of their engine.

On a boosted application (d1x,built motor) what would you Suggest for the valve covers, crank, oem weird thing and intake manifold spots. My crank is currently blocked off. (Caped) can pm also
