i recently rebuilt my motor, and to my surprise it was still burning exactly tthe same amount of oil, it used to burn. which is about one quart or one liter eever 2000 km. I thiink it works out too 1500miles. Anyway i was on the interenet and read somethng about a Greddy Oil Catch can. There are sooo many advantages to having it, but i feel I need the real Jbody input on this one.
Before I go on about the advantages you have to understand what it does, basically if you have an intake like a warm air intake, instead of sending the pcv hose directly too it, you would make it go to the catch can (its basically a can witha breather filter on top) the can seperates the oil (hence the car wont burn the oil) and evaporates the blowby gases through the breather filter (the blowby gases if contained in the block could ruin your gaskets, etc)
So the advantages,
Seperates oil
evaporates unwanted gases,
so coming from theee other end of the can is a hose of clean air that goes to your intake.
and it looks nice. CHROME
So what do you guys think, would it resolve my buring oil issue and should i buy it?
Heres a link to how it looks

I seriously doubt your loosing a quart of oil every 1500 miles past the PCV valve. You have a leak somewhere or its blowing past your pistons and getting burnt. You ever notice any blue smoke coming from the exhaust?
I wouldn't waste $100 on a catch can, but thats my opinion.
Well the catch can mod has been around for a long time. You would be surprised how much oil is lost over a oil change through the PCV valve system. Do you have a 2.4? If so it has a air.oil seperator already, but oil still gets around it.
I would get the catch can, but not route it back to the intake, route it to the stock air/oil sperator to deposit the oil back into the motor (so you still have the oil). Are you boosted?
It is a good mod.

Hi friends. Sorry to take this thread from death, but I have some doubts and you can help me.
I was thinking in an oil catch tank for a SCed engine, but I want to know:
1.- where is the air/oil separator you mention that LD9 engine have? is exactly under the SC?
2.- where could be the right way to use it in our engines? places? Pics are welcome to.
3.- which unit are good? I was thinking in a Greddy or a Sard oil catch tank.
My climate is very hot, and this mod could help me to maintain intake air as clean (engine fumes) as posible.
I appreciatte your comments.
Thanks,

Talk to Event..
I know he just did this install maybe no more than a month ago. An dhas been testing it out. He has a 2.2 but the principle remains the same. He Also used steel wool at the bottom of the can to act as a filter and a used an in line clear fuel filter so nothing makes back into the intake but recirculated gas.
Pretty cool set up. And the last time I looked at it you could see how much crap it catches just by looking at how the inlet tube changes color from clear (new) to brown .
I also saw the one he got, it's not Greddy,( he tried but I think there was a back order or something) but it's a daamn good looking piece. Nice and sturdy, billet.
Say it with me, "Its not what you know...It's what you can prove"
I wonder if you can just use a air/water seperator like the ones used on compressors for pneumatic tools. I have a ton of extras at my shop. it should serve the same principle, right? or is the engine vaccum not enough to make it pheasable?

Yes the stock oil/air sperator is under the intake manifold on the bloak on the LD9.
Truly you could make this mod for less than a greddy one. Also search ebay they have nice ones for about $30, plus shipping.

I know what are you talking about. In fact I am thinking in a good and renowned oil catch can like the expensive Greddy one because I think that internally it could be baffled and some of filter too. Something like this:
Do you know if the Greddy one or other cheap oil catch tank have similar characteristics?

I have read some times about it, but I don't know if it could last in a hostile enviroment like an engine bay, hot temps, water, gas, hot oil, really hot engine fumes, vacuum and some little boost sometimes for boosted engines. Remember that many of this air/water separators are plastic units.
Inclusive what happends when the oil almost fill up the canister or the filter element? maybe it can collapse and the engine will not exhale the fumes through it?
That are the reason that I am looking for a more automotive solution. Anyway I could be wrong. Comments and suggestions are welcome.
Thanks,

Only issue, you wont need anything that big. I have had less then a teaspoon come through the VC to have any reason for a catch can.
Nice Catch can Eliot.. My question is, where do you route the stock hose on the LD9 oil\air seperator if you use a catch can..?
Yeah, bring it back from the dead hehe..

Hi, well the catch can should be routed in the middle of the hose that comes from OEM air/oil separator and the TB inlet, avoinding any vaccum losses. That way you force all the oily air come through it without lossing vaccum pressure for the intake pipe.

It is a good mod.
I'm going to bring an old post back from the dead.
With my car being a 2.4L with the GM S/C on it, I want to add a catch can. I'm getting alot of oil in my intake, found this when I cleaned my K&N filter (found a small puddle in the black extender piece on the TB). My car only started to burn oil after putting the GM S/C kit on the car(PCV system not working properly I'm assuming with the S/C under boost). I was going to put the catch can in route from the PCV baffle on the block then to the catch can then to the TB where the hose normally goes in the black metal piece which attaches to the TB.
But my question is as seen above "route it to the stock air/oil seperator to deposit the oil back into the motor"
Can anyone post pictures or give more information on what was said above? where is the stock air/oil seperator?
Regards,
I now have the GM charger on my car. I got a catch can as well. I did not route it back to the block either. Oil will collect in the can until a empty it.

John,
If you can. Can you please post pictures of your setup. It would be much appriciated.
Regards,
So on the 2200ohv you would put a catch can inline with the hose that comes out of the valve cover and goes to the intake right. And the steel wool prevents the oil from splashing back up into the intake out of the can huh.

I will get them later this week. Out of town for work right now.

Oil Catch can the easy way (no wallet breaking needed):
Home Depot or Lowes: Oil/air separator from the power tools department
Auto Zone Silicone hose
total cost: ~$20
Sorry I forgot about this. First picture is of the catch can, it is mounted under my intake.
Second picture is showing the 2 hoses coming off of it. One going to the hose coming off the oil/air seperator on the block. The other you see going to the intake.

John,
Thanks for posting the pictures. Once I get some money I'm gonna pick up one.
