srt-4 turbo question again, oil feed.

i never used a restrictor on my car. never had a problem yet with oil. one thing to make sure though is that if you do a catch can (if you dont alota oil will come out the valve cover) make sure you put it in correctly with a check valve. if you dont you will load the motor up with pressure after a pull and push oil through the seals also.. .. im most likely wrong but i think it keeps some pressure off the seals of the turbo on some kinds so it doesnt push the oil past. .. atleast thats what i heard somewere.i think lol. think some types only require a smal lamount o oil and arent designed to handle what the pump sends

i actually had 2 catch cans on my car.....
1 between the valve cover and intake manifold and the other between the breather and the valve cover....
worked great, but you will deffinately need the check valves.....
when i spun a bearing on my stock turbo motor (before the built motor) it was because i didnt have a catch can or check valve in place......i really got on the gas when pulling out of a parking lot and the car dumped about 3 quarts of oil out of the breather on the valve cover

I dont want to make another thread, so I will just stay on this one. Next question: I got the chill factory rrfpr. There are two vacuum hook ups, and 2 adjustable *****. One vacuum has a one way valve on it. I assume by the one way valve that the little one on the side is for boost, and the center one is for idle. Is that correct? So can I adjust the rate of gain during boost with the other one? Can anyone explain this?

ok when i ran my catch can (CC) i did it like this
-attach a hose to the pcv valve nipple
-attach one to the breather nipple
-using a barbed y fitting from vacume line join them together
-route the third end of the 'y' to the CC in barb
-2 ways to do this.. you can use a check valve and put the outgoing hose from the CC to the intake manifold barb. what i did was make a small ghetto intake for my turbo and put a nipple on the side of it. i put the outgoin hose from the CC to this so it will always be under vacume and keeping my oiling system good
side note: if you dont use a check valve or the CC out hose is put anywhere on the manifold or anyplace that sees boost you will hurt things. when i hooked it up wrong and had no check valve after a few seconds the CC became pressurized from boost and forced pressure into the motor. this make it so oil pressure built up in my turbo and it pushed oil out the compressor seals and resulted in alota smoke and burnt oil
carefully look and you can see how mine is routed

2 things, oil restrictors are just a narrow orfice about 3/16" or -3 an that keeps oil pressure from blowing out the seals in the turbocharger. A note if you disagree, remember that as velocity increases, pressure decreases. And vice-versa. You can usually avoid this by using -3 lines.
Which way does the check valve work, in or out of the regulator? The **** likely adjusts the rate, 10:1, 12:1 etc. Which to use tho hmmm...
Oh and my DOHC sucks PCV oil like crazy, pools in the bottom of the intake a catch can would be nice
