in theory, this item can/will be a very effective safeguard for your upper end of the motor/intake (especially the new crawdaddie enroute to yers truely)...
now, to explain::::
the rear intake tube (aka Z-tube) has an inlet hose (15mm i think??) that is a rubber ventilation hose, stemming from a barb on the crankcase...... this vent actually helps to remove hot gasses in the crank (and by venting to the intake system on the motor, a minor vacuum pressure is present)...
this is done for two (main) reasons::::
1) emissions..... by reburning gasses, the exhaust will be cleaner
2) crank pressure contamination........ removing hot oily gas helps the crank spin better...
so............
should this be the solution??? to act as an intermediate in the crankcase hose and the throttle body??? where to mount this also??
questions, questions, questions.............
now i need advice.......
Brand New. Reservoir Tank is made from 6061 T6 lightweight aircraft grade billet aluminum cylinders.
Oil Catch Tanks collect the oil, moisture and blow-by gas that causes carbon and sludge build-up in the intake system and engine to keep them clean even under the hardest driving conditions. An Oil Catch tank is also an excellent engine dress up item that will give your car the race car look
How much is that thing? There are quite a few Z guys running a catch can and it's not a bad idea at all, but there are likely cheaper ones than that. I know Greddy makes one. Search around the Z forum for info and pics of it installed. I've seen most of them installed off to the right of the intake tube on the strut bulkhead.
With everything he's putting in this car, would you expect anything less of him?
I aggree that from what I've read, it is really only benneficial if you are FI or do a lot of top end driving, but it is a fairly cheap mod and good eye candy. Certainly wouldn't hurt to have one.
BTW, is that one a genuine Nismo product? Doesn't really look like it from the logo font and packaging design.
Well if you could post some on how much the price would be reduced via group buy I may be interested. It's really only for dress-up.
I took apart my PopCharger and Z-tube and looked inside the tube and all and there was no oil residue. Meaning that no oil came up thru the vacuum tube. Took a clean cloth and wiped the inside and it came back out clean too.
Popcharger does it's job filtering! Also no oil coming from the vacuum tube!
So that just shows that the above would be for engine dress-up.
Es, it would come in handy for you with your vortech coming in though!

You're looking in the wrong place. The oil blow-by would accumulate under the plenum (it come's through the tube on the underside of the Z-tube, which is after the filter, so that filter itself really has nothing to do with it). I noticed a very small amount on the underside of my plenum when I put on the Crawford; nothing to worry about, but there really shouldn't be any and I only had about 4000 miles at the time.
Some interesting info. in this thread: http://www.my350z.com/forum/showthread. ... adid=51064
See Skidazzle's posts. I'm not really understanding his logic, though; he confirms that oil is getting into the plenum, but decided not to put in a catch can? It looks as if the oil is really coming from the PCV hose on the pass side, NOT the hose connected to the intake tube. Still can't figure out why he didn't want to put one on that side, though. Anyway, it's late, I'm tired; somebody else figure it out.
Oil definitely comes out of the PVC valve and is being sucked into the plenum. I have a home made catch filter installed in-line between the PVC valve and plenum intake, it has been collecting oil for the past 2000 miles. I'll post a picture later. I'm not sure if there are any other paths that the oil could take to make its way into the the intake, need to read the service manual.
So do most other people and that's where the majority of them mount it. I'm not saying for sure that what I sated above is the absolute case in all situations; I just happened to find that thread where a couple of people actually tested it to see where they were getting oil. Skidazzle has one of the most heavily modded street Zs out there 400RWHP custom turbo set-up), so I tend to believe what he says and he's not using a catch can at all.
Exhaust Dilemma. Bosal kit from RockAuto or G35 HKS knockoff from eBay?
Pretty straight forward. I'm killing myself trying to decide what to do to replace my stock exhaust.
I really like the stock exhaust sound, I'm not trying to get too far away from that - but the options for a 2004 FX35...
Hi. I’m new here and looking to build a new spare motor for my 08’ fx35 AWD. From what I can gather so far is it possible to get a VQ40DE bottom end and put VQ35DE heads and manifolds on it to bolt in and plug and play? I read the 4.0 is taller. What are the best heads to use and so on? I...

I have a 2007 FX 35 and need to replace the rear muffler, muffler only. Can anyone suggest an after market muffler that costs less than $500? I see that Bosal offers a muffler, does anyone have any experience with their product?
Just a head's up - I am also working with InsaneAmine (http://www.z-xtreme.com) on a grounding kit for the FX35. I saw Esemes mention he was working with him on the FX45, and I contacted InsaneAmine also :)
Anyways, they should arrive Wed/Thur of this week. I will post a pic when they...
