My car + crawford cats + oil catch can =

I don't find it shocking that your modded sedan 6MT was outrunning that 350Z considering your mods and your experience compared to his ill choosen mods and most importantly, lack of experience. I'm certain the Z would be fractionally quicker than your G with you behind the wheel of the Z.
And while I would like to believe that I could have wrung out better times from his z than he did, that would be unfair. And so nobody that's reading this thread takes it the wrong way, let me make something clear. I am in no way stating that my car is faster than a z. On this particular day, with these two cars and drivers, I was faster.

BTW, I'm wasn't trying to imply your car was significantly slower than a 350Z and that he should have owned you. The performance difference between the 350Z and G35 is far closer than most Z guys would care to admit. I'm certain that if you were to run 26" slicks and choose to launch at 5000rpms, your G would easily be in the 13.3-13.4 range in cooler air. I'm certain of it. Yank out the passenger seats and 13.2-13.3 should be possible.

I wanted to let everyone know when I removed my MREV and I had the catch can on as well. I never reopened the upper collector and lower to clean it after installing the catch.
Well to my surprise, I had OIL everwhere in my intake plenum. Lower/Upper collector had oil just coated on all the walls. I had oil even on the white spacers for the kit sitting. OIL is getting into the engine. No doubt about that. If you push your car hard like I have with my racing, oil is getting out of that center section and getting into the intake system. After installing that catch I noticed a power improvement. I use to see a loss in power sometimes and ever since I added the Catch I never saw that anymore.
Oil in the intake will lower your octane and cause your car to ping some then cause your car to reduce timing.
The catch can works.

after removing the filter element.. trying to make sure that my new hose doesn't collapse under idling..
My car still stalls whenever it is a warm start up, I have to bleep the throttle a bit to get the engine going.
However, I am wondering if anyone knows what causes a:
1) Normal stall
2) In this case, a stall with the installation of an oil catch can..

Thanks alot Russ..
I will do that tonite after work..
+ I will also experiement if it is because of:
1) longer hose length (by connecting the two hoses with just a connector)
2) the fuel injector hose being too restrictive (this shouldn't be the case since it is 3/8" in inner DIA. ..but well, I will check that too)
let's hope my engine doesn't stall when I put my pcv back on without the new hose and catch can ..

Just like how you are in the shower and STEAM gets all over. OIL vapors get all over.
It is one of the best because it obviously works. This is from experience unlike yourself.
Why do you always have to be so negative on every freakin mod?

I was surprised, because I initially expected the catch can to catch *all* the oil. Then I realized that obviously it can't. As described elsewhere, this "makeshift" catch can is a temporary measure, and was in no way engineered to the purposes for which we are using it. It's obviously functioning to a degree; I've collected a not-insignificant amount of oil myself.
Last night I examined my old oem lower collector sitting in my garage(left over from the mrev swap). It was coated in residue(as were both mine and Cheryl's upper collectors). I ran a finger inside the runners where they travel down to the intake manifold, and wasn't surpised to see quite a bit of residue there as well. Despite speculation to the contrary, with the stock setup, oil is in fact entering the runners and not just collecting in the valleys.
