i see these "universal " oil catch cans on ebay they are all like around 20 bucks.....i know the old saying you get what you pay for.....but dont these all do roughly the same thing? im willlin to pay for the amw catch can.....but i just wanted everyones opinion on these cheaper ones.
thanks

 

What is a catch can?

 

Why pay in excess of $150 to buy a fancy one, when the ones on ebay do the same thing.

Catch cans plug into your PCV lines and prevent oil from depositing in your intake.

 

thats what i figured just wanted to hear it from someone smarter than me

 

Better yet make your own for 25 bucks. Go to home depot and buy a water seperator, tubbing and nipple attachments. I have had mine on for a while now with no problems.
You will get some people who say you get what you pay for, etc, etc, etc. Ignore them. The catch cans are all the same.
If you wants pics/examples let me know.

 

I would like some pics!

 

Those $20 ebay cans DO NOT WORK. There is no filter element to catch the vapors in them...it is simply a can with a input hose going in and a output hose coming out.
I had a AMW can on my truck, it would fill up after about 1k miles. I took it off and put it on my TA, and bought the ebay can to put on the truck since it was a bigger can...after 3k miles, it has only a few drops in it.
I bought my AMW can several years ago at about $80-90....now they are $160 which is rediculous for what it is...it is a very nice piece, but not $160 nice.
If you don't want to spend that kind of money, get the air compressor filtering device mentioned above as it works and is designed to do exactly watch a catch can is supposed to do. The ebay one is just like a fat spot in the vacumm line and does nothing unless the liquid is not vaporized..and if you have that much liquid coming thru the vac line something else is majorly wrong.

 

This is the one I got....going in this spring.

anyone have pics of any other catch cans?

 

That looks like a nice one that will work fine since it has a filtered top.
The AMW can works with just a brillo like steel filter in the top much like that one, not sure how that captures the vapors, but it works.
I just bought an air compressor vapor filter at Home Depot to use to replace the ebay one, it may prove to be too small as it can only hold about 3-4 oz, so I may end up buying the one you posted.

Mook, do a search on Google for "oil catch can", and you will get a ton of different catch cans for about $90, Perrin and Greddy are a couple, but I do not know if those have a filter in them either...I'm going to guess that they do not just by looking at their construction as it appears that they do not disassemble like the one above and the AMW one does.

 

It works because when the vapors are coming thru the can they touch the brillo material (which is colder than the temp at which oil vaporizes) and condenses into oil droplets then fall into the bottom of the can.
So you see, it doesn't caputre the vapors at all, it just condenses the oil out of the air stream.

 

Makes sense I've learned something for the day...I can go home now

 

yea i've had the home depot setup for a few months now....works great. check out the 2nd page of my cardomain for pics and more info. total setup was under $30.

 

What AL said is correct , the " brillo " is just the media for the can . We used the metal shavings from the machine shop at the nuclear power plant where I used to work at as the media for the oil catch cans on all the large pumps throughout the plant and it worked excellent. On those ebay cans ,all you have to do to make them work like they should is to stuff them with coarse steel wool which you can buy at any hardware store. It is a little time consuming , but it is cheap and it works.

 

The problem is the inlet and outlet are right next to each other, so unless you stuff the entire can with brillo, the air will pass right into one inlet and right out the outlet without having to travel thru the brillo. Not to mention the hole in these ebay cans is less than 1/2" in diameter, they cannot be taken apart, so stuffin it full will be time consuming.
The Home Depot Air compressor separator/filter is a much easier route and a hose can can connected to the bottom of it so it can be drained very easy without removal.
