PS sorry for bringing this back from the dead.

 

Or get the best and install 2 OCC.

 

nah dont be it reminded me that i need to do this mod.

 

if you install 2 occ should they be the same mfg?

 

i did my diy occ today, pics to come.

 

No unless you want them to look alike, mfg has nothing to do with function.

 

...and the only one that I know of that is actually functional is the PCV Catch Can manufactured by Accurate Machine Works in Bryan, TX. All the others are junk. Visit their web site to see what a catch can is supposed to do.

 

Don,

I personally have the highest regard for your experience and your thoughts. I count you as one of the few vendor guys who really has something meaningful to contribute and I always read your posts.

But think about this...

How wise is it to call other vendors' products junk on this board, when you are a vendor yourself? In this case, it's not about whether or not you're right, but about common sense and courtesy. Or isn't it?

 

Ouch!! Their catch can looks to work the same as the others....Other than its all aluminum and looks more expensive. Am I correct?

 

How about not "junk" but rather "not all that efficient and better products are available?”
I realize that emotions of many folks come into play but in life I think truth matters above all else.
I do not have to sell anything to make a living thus I can be objective in my observations. That alone ought to make Mini consumers pleased. If they want a product that works I can probably help them out. If they want to appease their emotions there are Vendors other than me that can help them out.
Remember: It’s far easier to hamper a Mini’s performance than to enhance it.

 

No, you are not. Ever look inside many "catch cans?" What do you see?

 

Don's a track rat so to speak. He really doesn't care much for being peoples friends or being courteous... Generally track people care about performance, faster lap times and what works... ala being right.

I'm not trying to put words in his mouth but.... from the convo's ive had with him... he cares about being right and not pleasing people.

 

The difference in this can is the internal mesh "filter". Any/ALL OCC work better if there is some type of "filter" as opposed to just an empty can.

All one needs to do is add steel wool and your can will be as effective as the one DMH references. To go a step further - on the inbound inlet of the OCC - add some tubing to extend down into the can. This forces the inbound air to travel a greater distance inside the can to exit. The combo of the extenstion tube and steel wool "filter" is optimal.

I extended my inbound tube down 2/3 into the can - having done so means I also need to check my OCC more frequently otherwise I will be blowing oily bubbles inside which defeats the purpose. My down tube is heavy plastic.

 

my walmart special works pi$$a !! and only 16.00

 

Still no excuse for that kind of comment.

 

Could you not run the risk of getting small pieces of steel wire in the output?

 

Well anything is possible, so yes. But what will happen is rust will develope, that I can promise you. Alta includes a package of foam with their kits now that act as the filter media.

 

I think the same way about PCV cans as I do CAI: They add very little benefit but if you are going to the time and expense of installing a PVC catch can do it right from the beginning. That means buying one that is designed properly and thus does not need to be altered internally or externally to work properly. For $160 you can buy the stainless steel AMW that works like this: Oil vapors and other contaminates are first caught and condensed by a stainless mesh and then dropped to the bottom of the can where a series of under-cuts in the walls prevent the oil from climbing back to the top and exiting back into the intake tract.

 

I wasn't able to find a web site for AMW. Any links or pics you could post of their OCC?
Thanks

I check my can about every 3 months and at that time I typically just - open can, dump contents, risen can, insert new steel wool, close can and reinstall.
Its cheap enough and since everything gets coated in oil, I have not seen any rust develop but then again - every 3 months. Also you can purchase "steel wool" in metals such as copper.

I installed an Alta OCC w/ a friend and I'm sure foam works too. The important thing here that Don is pointing out - is that an OCC objective is to trap oil and just installing a "CAN" doesn't accomplish much. An OCC w/ mesh, foam, steel wool will trap more than an empty OCC can.

 

shooler,
Thanks a bunch

 

Agree! However when I had steelwool in mine the clear tube started to turn rust brown within weeks and when I opened to check it out I was suprised with the amount of sediment that was collecting. I still can't get the tube clean.

It could be my steelwool is just ancient, it got to be at least 15 years old.

 

Huh !?! !?

 

Dude, time to replace - don't ya think ?
