This item keeps that crap from returning to the combustion chamber. If you have questions, please email me and I can send pictures and info.
This attactment is a prototype. I will update with my polished can later tonight.

Seriously, there’s nothing wrong with talking well about an item you like and introducing it to the rest of us. Hell, actually I think your catch can looks great as well and would probably consider buying one if I ever wanted to replace my Greddy, especially if the manufacturer becomes a board sponsor.
My only issue was, that you came on here and started bashing the Greddy can (making false claims about it’s quality) that works great for most everyone that’s used it. I just don’t think you need to bash one item to promote another, IMO. 
I do agree though, that the hoses supplied with the Greddy are not very good, but it really wouldn’t have mattered to me what hose it came with, because I needed about 6 feet of line each way to mount it where I wanted and I doubt any of the catch cans come with 12 feet of line anyway. Either way I’d have to supply my own line in my application.
If you could, please PM me the price on this can. I may be interested in using it for another car.

BlackHawk131... thanks for the PM. I will think about it.
I may be moving my Greddy can to another one of my cars because I think it would fit perfect on that car, due to the square design. If I do that, then my T/A will need a new can.
Is there any way you can post some more pics of how & where you mounted it? Thanks.

AMW Catch Can Installed It's been a few days now since I installed the Accurate Machine Works Catch Can and I can say that I'm pretty pleased so far. I thought real hard on where to put the darn thing... Let's see - it so small it can go behind the driver's side radiator, behind the passenger headlight, where the traction control would go, on the driver's side of the radiator, and other places if you have more ingenuity.
Ultimately, I opted to make a five inch aluminum bracket and mount it directly to the passenger-side cylinder head. There's lot's of room there and it looks fairly stock, expect for the shiny brass fittings that should fade in time. I just love how short the lines need to be. I think I only used 10 inches of the many feet of hose that was supplied. Here's a few pics. Sweet Huh?

White01ss,
Looks good I just have one question. I don't see any headers or anything? Everyone I've talked to didn't start loosing oil until headers or cam or both were installed. Are you just doing it before hand? Or were you loosing oil in stock form? I've had a few LS1's and have never lost oil in stock form that is why I am asking. I like your mounting location.

No, it will not prevent you from losing oil, but it will prevent it from getting sucked back into your intake if it is the PCV that is causing your consumption. (In which case you will be draining that can pretty often!)
But I bet you are burning some oil also (oil rings)...

If you think the headers is the problem, you are way wrong. Don't be fooled by someone telling you that kind of crap. This is a problem on all with a pcv.

The only way I know of to see if your engine is passing oil through the PCV is to have one of these types of devices in place. I did check it tonight and it was bone dry so far after 40 miles with nearly no full throttle action because it's been raining so much. Either way, I expect to see something in there after a few thousand miles.
As far as headers go, I have no idea if they can make the problem worse. I would think lots of WOT would be the biggest factor since that's when blow by gases are going to pressurize the crankcase. If you were to cap off those valve cover breathers the pressure build up would blow out the gaskets which would cause oil leaks galore.
Lots of cars from the sixties and earlier would just vent from the valve cover through a breather, but that's not very enviromentally friendly since that's hot exhaust bypassing the cats.
Here's some zoomed in pics of the front and back of the bracket. That big wad of aluminum is a bunch of washers and nuts wrapped in aluminum tape I used to keep the bracket level in case the 10mm bolt becomes loose. It rests on the lip of the valve cover. It'll do for now.

Wel I know for a fact that a cam depending on the specs ETC... can and will change the amount of vacum a motor will pull, so I am thinking that with the headers it is sorta the samething. They flow better than the stock manifolds so the engine pull more air into the chamber creating more vacum especially under hard acceleration. Now I know I did not explain that right but maybe you get what I am trying to say? More vacum on the intake will pull more through the PVC system with more oil ETC... Not my best explaination but it is 3 am and I am tired.

This is FACT. There used to be polls on this site about this very issue and most people who had oil consumption/smoke at WOT started to experience it a lot worse after headers and/or cam swap. It is far from coincidence, it is in fact a real issue.
Believe what you want, what do I care, but don't make blanket statements when you don't understand the facts. There is enough misinformation on these boards already.
I'm done....

Right on Tommy! Do you think $88.50 is worth it for a can? I can only imagine how much the Greddy was! This must be the GM price I was quoted or someone is getting serious kickbacks from this product. Just my 2 cents.

This is the Greddy I bought for $99 - http://www.machv.com/groilcacan.html
There also seems to be another Greddy can for $84, but this is the first I've seen of it - http://www.300zxstore.com/greddycatchcan.html
