Can anyone tell me of an oil catch can that is baffled? I want to get a catch can to relieve/vent my crankcase. I've just been venting the crankcase to the atmoshpere and its not enough. Most of the catch cans I've been looking at aren't baffled like the Greddy unit, which to me doesn't make it any better than the copies that are floating around.
Cusco/Sard are they baffled? I saw a Perrin catch can and I didin't like the design of it and for the price forget about it.
I'm thinking of just getting a copy and cutting it in half and welding in a baffle. What do you think?
Edit: Just found this, looks interesting. AMW catch can (http://www.accmachtech.com/pcvcatchcans.htm) that is baffled.

Hmmm. Boomba has alot of good feedback for that catch can. Some people mentioned an internal baffle, but I wish I could find some pics of that can taken apart to see the internal design.
I will definetly keep that catch can in mind. Thanks :thumbup:

can you explain what baffled vs unbaffled does? i assume it helps to catch the oil from being passed through the can?

Just from a quick read around like you just said it helps with catching the oil from going back to the intake track. I figured if there isn't a baffle in place to seperate the inlet and the outlet the oil/water vapors will go into the catch can but continue on into the intake. Like the Greddy catch cans the inlet/outlet are at the same level and without a baffle so oil in then oil out.
So if you ad a baffle it will keep the two lines seperate and help with condensing and slowing the oil/water that is going in and help it not track back to the intake.
Here is a simple right-up I just came across that modifies a Greddy catch can with some mesh and a piece of pipe to act like a baffle. Greddy catch can MOD (http://vamp.darkravers.net/TipsGreddyOilCatchCan.cfm)

thats why I like the homedepot water seperator(I use it as a catch can) works great for me.

Next time I see you with your car, make sure you remind me so I can check it out..
What color is it and how big is it? Fairly air tight?

It was a couple bucks from Depot. It's airtight. It has a little nipple on the bottom so you can emty it without taking it off and it's like 4inchs tall. It's not real big. I used to drive my car 100+miles a day when I emtied it once a month
Edit: black top to it with a clear "tank" that screws on to the top part, and brass fittings for the two hoses.

What isle so I can check it out? LoL.. Wouldn't mind running that for awhile until I can get one from AMW or maybe one from Boomba.

it's with the air compressor stuff just has for a water seperator they know what they are.

Cool, thanks man..
Edit: On post number 5. I think the Greddy catch can mod can be made even better with a shorter piece of pipe with a 45 degree elbow with another short length of pipe to "shoot" the oil/water straight down into the mesh. This will leave even less of a chance for the oil and water to track back to the intake.

lol look on SRT forums...look for "welfare mods" i think it costs like 20$ and its just as efficient.

i don't really trust steel wool as a true baffle... b/c not all the vapors go through it 100 percent...
one thing i would try is an inline filter which would definatly catch oil vapors...
one that is reusable too

steel wool? The thing I have has no steel wool it has a small baffle inside.

Very true, but its better than having nothing. I think the whole point of the steel wool is to slow down or help condense the vapor. The actual baffleing would be coming from the make shift pipe changing the entry/exit points of the vapor's.
The inline enclosed filter would be a good idea also. Would you put that before or after the air/water seperator? Or run it by itself?
Maybe before the catch can to condense the vapor so that it could drip/splatter into the catch can?

I think he's talking about the link up top that modifies a greddy catch can.

the wool helps create more surface area and to disrupt airflow in the can. this allows the oil to precipitate out of the air.
I'm also doing my homework on catch cans since my galant is an oil pig.

Ok, I tried the Home Depot catch can mod and it works!! Not only does it work but I kinda like the way the can looks also.
I went to Home Depot and got a Husky air compressor filter with 3/8's hose connector's. Plumbed it in and went for a cruise got back home and looked at the catch can and it cought about 2-3 ounces of nasty fluid!
Maybe later I'll throw some steel wool in there to help and I kept the 5 micron filter in there also.
The Husky oil/water seperator cost around 20 bucks and is internaly baffled..:)

sweet, glad it worked out for you. I'll be doing the same when I get home.
now question for you - how 'nasty' is that fluid you're catching? same color as your motor oil or is it fouled up?
Silverfc88

Its about the same color as the motor oil but very watery.
I need to make a bracket for the stupid thing now its just kinda hangin around..
themadhatter

watery cause the husky filter is really an air/water seperator and it's pulling the humidity out of the air as well. take the micron filter ouf of it and see what happens.
you'll most likely get clean or similiar condition oil as to what is in your motor. you can then pour that seperated oil right back into your motor.

just checking in to see if you have an update. so far so good?

Yeah so far so good for me. Now its starting to look like that milky white stuff with a little bit of oil sitting at the bottom, but I haven't driven it for the last couple of days. I'll update more later with some pics.

My Perrin catch can came with foam materal to put inside it for more surface area. Don't know if thats any help to you.

Do you happen to have pics on what this foam material looks like? I already put some steel wool in it and I kept the little filter on it cause I'm scared of sucking in metal material. Works pretty good.

i don't have any pics. It's just like strips of fine foam sponge stuff. I can't really think of anything to compare it to. It looks like something you might find at an art/crafts store for painting or something. the amount it came with was enough to fill the can very loosly.

I don't have a catch can installed right now. I used to have this husty installed on my old motor setup. I used it for about 6-7 months and had no problems. I also used one on all of my talons and had no problems with it. Only thing is on one of my talons I had some blow by and had to empty it like 3 times a month(still not too bad)
