Anyone have an installation picture of the following oil catch can from LG Motorsports?



I got this along with the bracket to mount it. Just got back from a trip and been looking for a place to mount it. I found one, but I would need to drill one hole. Also, interested which lines I run to and from it.

You would think the instructions would show that stuff - I have a dirrerent one but the concept is the same



It doesn't matter which line goes left or right - which ever is the cleanest to where you mount it - I didn't have a pic of the lines behind the throttle body - sorry - hope this helps

The only way to keep all of the oil out of the intake is to not run the line back into it, and the only way to do that is with a breather can. All of the cans above will let "some" oil back into the intake, ask me how I know.

The 2nd one down the page is the one I use:

One line goes from the valley cover to the can, another goes from the top of the dry sump tank to the can. I then cap the intake inlet and the inlet in front of the TB that the oil tank vent line is connected to. I mounted the can on the radiator side of the void in the front right of the engine bay (to the shroud). I have a short line running out of the valve at the bottom of the can for easy draining.

Zero oil gets in my intake.

I am interested also, I have this one sitting in my garage since January.

Cartek sells something similar to this, but it includes mounting brackets for Corvettes.

Okay - How do you know?

And post pictures and details of your setup........

Well, I was just hoping someone had a picture. Over a week ago I got a reply from LG that they were working on an installation guide for this, it's still not posted. So I was hoping to jump the gun as I'm heading out to Denver next week and want to install it. Will be tracking the car with my brother in law (mod'ed M3) and want to keep the oil out of the intake.

Hey LG - post the install instructions or a picture! I've figured out where the lines run but I can't figure out where the bracket you included bolts up. Spent some time under the hood this weekend and still am scratching my head. (I installed the under hood light and Z06 liner)

Between my neighbor and I, we have tried both of the setups pictured above. Both let oil into the intake. The Cartek can is basically the same thing, only not quite as easy to drain. I would post pics but the engine is out of the car and everything is unhooked.

I like that Jaz Breather, how much is it ? (no prices on their web site)
Thanks,
Mike

Are these things really necessary for the LS7? Is it just supposed to increase engine life or what? I like the look of the LG one though, looks to be about $130 with the brackets, online price.

About 6 years ago I bought on of those catch cans for my S2000. I never installed it beacuse I thought it was a POS. Very heavy, and no internal baffling. Also, the same problem you are having - very difficult to install. I eventually threw it in the trash.

Sorry no picks at this time as I am at work.

I installed the LG can the same way as your old car install. Pulled the U hose. One line goes to the motor the other to the intake. Immediately it through a code. Called OnStar they said it was getting too much oxygen.

I might try dfinke23 install to see if that changes anything on the codes but at Mid-Ohio it ran fine other that the check engine light.

Also I change out the clear plastic hose that comes with the kit with some 3/8 Fuel line.

Yea, both the Cartek and Jaz are breather cans not catch cans. Both "catch" very little because they vent the pressure to the atmosphere. However, my intake is bone dry, so it's doing it's job of keeping oil out of the intake airflow.

The Cartek can is a bitch to drain. It requires removal to access the drain port. Not a very good solution. I started smelling a lot of oil when the car was running so I pulled it and checked it. I drained about 1 cup of WATER and maybe two tablespoons of thick sludge. Must be condensation forming in the can.

dfinke23

I agree on the condensation, that is why I went with the polymer Jaz can over the aluminum Cartek can. You are correct that the breather cans allow any pressure buidup to release through the filter, but the filter does catch the oil mist (about 1 tsp per track day). I have no oil smell in the cabin as some others have experienced with the Cartek can.

dfinke23

The LG can will not operate as the Jaz can does because it does not have a breather. You may as well just cap the valley cover outlet and not use a can at all, or run a line from the valley cover outlet to the dry sump vent fitting, and cap the fitting in front of the TB.

For anyone considering free-venting the vapors like this, err on the side of caution and change your oil very frequently, because you are likely letting more of the contaminants (including moisture) stay in your crankcase and valve covers as a result, which then gets combined with the oil. The LSx motors rely on the intake suction to help pull the nasty vapors out of these areas, and free-venting will not be nearly as effective, which means your oil will contaminate more quickly. That said, it also applies for producing lower emissions, as the point of feeding the vapors back into the cylinders is to burn them up and pass it through the cats before releasing into the atmosphere.

I have catch can on my LS6's valve cover and PCV hoses, which I T'ed together to enter the can, and then T'ed the line going out to the two intake ports to maintain the vacuum. With that I catch a quart per race weekend, which is what I used to "burn". I no longer get the oily residue all over my back bumper, and no more black soot in the exhaust tips, so it has made a huge difference.
