PCV breather and oil catch-can questions

[Djstorm100]

I don't know if it has been stated yet or not. BUT the pcv system needs to be from the valve cover to the intake of the s/c and with the catch can in between those. This is to put a vaccum on the pcv at all times and help with pressure in the crank case. This is truly a subject that get's beat to death. Put a sponge or some type of material in there

I did this to be safe.

^ that's correct

Just run 2 breathers and call it good...

Except open breathers will spray oil all over the place under hood at times (like when under boost or heavy throttle even NA) so not ideal for any street driven car or track driven car that could be black flagged for oil burning underhood. Also on NA applications (I know this thread is about FI cars but there are likely NA guys in here as well) the vacuum from the intake mani or intake tube helps "pull out" positive crankcase pressure. On a FI setup I would run dual catch cans and a GT500 PCV valve as it is more restrictive vs the stocker and will not allow as much oil blow through so no one will be filling up cans after 20 minutes of hard driving.

No oil spray or drippings here ever.

If you need an oil to air seperator or breathers we sell both

^ Do you have a website?

 

[Bobby]

yes but you want find them on there. we are a vendor on here. just go here http://www.s197forum.com/forum/forumdisplay.php?f=150
what are you looking for exactly?
here is a pic of the oil to air seperator

How about give us the website address any way? Some of us might want to see what else you offer.

Here's what I use. Bought it off Amazon for $75. It has a drain in the bottom and works great. I have been using it since going with the Vortech last Dec.

So I ran the Moroso Separator(witch I dont think is a cure all) and ran it wrong, I ran it closed system just the two valve cover openings into the Moroso, Damn did I f up it shot my dip stick out two times then I said screw this and put it back to stock. So what I need to do is run it and run it back into the intake( I really dont want to do that but if it saves the motor) I wonder how the Boss 302R gets away with it not damaging the motor with no vacuum.

The moroso can is a sealed unit and it's meant to be installed inline. When you installed it with the lines going to each valve cover, you sealed the crankcase off. All that pressure had to go somewhere and it shot your dipstick out obviously. The set up on the 302s uses a vented catch tank. It's not a separator and doesn't function like one. It's the same effect as running little filters on the valve covers. It vents crank case gasses to the atmosphere. The race cars run them to catch the oil and keep it from going all over the track.

So this is how mines set up. From the passenger side I have running to the drivers, then it's teed to the can. The other end of the can if going to the air tube. My car is a daily driver and I only drag race 1-2 times a month if that getting 6-7 runs. Am I doing it right?

 

[JEWC_Motorsports]

I have the moroso unit, can someone please explain the correct way to hook up both valve covers to it? Please. I had switched from the moroso unit to breathers but after 500 or so miles i ended up with oil coming out of the drivers side breather. I reinstalled the moroso unit today back on the passenger side, id like to be able to use it for both sides instead of spending more money for a drivers side unit.

You should not hook the Moroso catch can up to both sides. The driver's side allows for air to go into the crank case and the passenger's side allows oil and gasses to escape. To use the Moroso can set the driver's side back to factory and hook the passenger side up with the tube going from the crank case to the can and then from the can to the intake.

If you want to set both sides up to a breather search for a Peterson breather
Here I did it for you:

I know some people are probably looking for concrete info.

Question i still have is, If you can remove 99% of the oil in the air is it better to reconnect back to intake for crankcase vacuum (NA car)?

Some good tech on the Peterson setup:

Damn you messed up those beautiful col pack covers. Man they look familiar
