I run one tank per side. I do not run a pcv on a forced induction engine. A drain back to the pan is fine and eliminates having to drain the tank, but many like to get that cruddy milky oil out of the engine (take a look inside a breather tank sometime), so they keep it separate and drain periodically.

Thanks Jody,

Excuse my ignorance on the PCV, but I know now. I appreciate the help.

no ignorance involved, there are guys who keep pcv with forced induction. I've just found it as one more thing to go wrong, i.e. pulling oil into the intake system. I prefer a pair of good breather tanks.

Jody-

Do you think that two vents, routed to tanks, would reduce pressure enough to solve the gasket issues without some sort of vacuum?

Jody did you run a setup like this on your 406 Procharger motor to?

If two #10 lines to breather tanks don't solve a pressure issue, then there's a seal problem with the engine; i.e. rings, valves, etc. It works fine for a forced induction or n/a engine that is in good shape, but may not fix something that has bad leakdown numbers. That needs to be repaired first.

Jody

no, I made a spiral baffle that fit inside the Moroso stands and K/N breathers in the valve covers; the engine had good leakdown numbers and this was fine, never pushed any oil out of the breathers.

Okay,

I have been watching this post and learning as much as possible. I plan to run a single catch can with a -10 line running off the back of each valve cover into a single tank.

there is also a good thread from a 2007 that i saved talking about this same thing.

Jody - can you please add your wisdon to this I would really appreciate it.

I figured out my issue with too much pressure. Leak down is terrible, so I've got something wrong in the motor. I will tear it down here in a couple of weeks. Its got 120 miles and hasn't got any better.

well, I have re-thought the breather line from the tank to the air filters. Still think it's the way to go, but you'll need an oil separator tank inline between the oil tank and air filter, or the extreme pull under boost from the air filter will pull oil right into the engine. At least that's what happened to me on my Chevelle. For now I've gone back to the breather caps on the tanks that Stef came with, and have disconnected the lines from the tanks to the filters. I'm not smelling or seeing any vapors anyway. Ideally the breather tanks would be separator tanks, so that the vacuum pull from the filters could only pull pressure, not oil. The Stef tanks I have are not and it pulls straight oil through if hooked to the filters.

Thing is, I'm not pushing any oil into the tanks, I haven't had any oil to drain out yet; but the vacuum pull from boosted turbo air filters will pull the oil from the engine, through the tanks, and into the turbos which is the last thing you want on a forced induction build.
