I have bought some stainless steel wool to use for the baffle in my oil catch can. Just wondering how much wool i should put in the can. I mean should i pack it in tight or just enough to fill the entire internal space loosely. Any feedback on other Luders setups much appreciated.

i did a crank breather setup and i am not even running a catch can, if done correctly, you shouldnt even have oil coming out of the stainlees hose,(unless your motor has worn rings) the bigger the line the less oil it will carry, just make sure you drilll the hole and the back of the valve cover where the baffles are.

It depends if it's an "open" or "close" system. If it's an open system (with a filter on top), then it wouldn't be any oil, as no vacuum is being used to pull oil vapor out. However, if it's a close system (using intake manifold vacuum which is same as oem setup) but no oil in the can, then it's not setup correctly.

I would cram that thing with as much baffle as you can. The air is going to take the path of least resistance and if you have big empty spaces at all the corners you won't filter much of anything...

You'll still get some oil, as all engines have some amount of leak. I was surprised at the amount of oil I found in the breather tank on my track only Prelude. It uses 4 -12AN lines going from the intake mani to the breather tank. The OEM PCV setup has been eliminated and all ports plugged, so there is nothing "sucking" the oil vapor out of the crank case. The only movement is due to crank case pressure.

As for the engine, it's puts down very good numbers. I don't recall the exact compression figures, buy they were all within 2% of each other. Leak is right around 1%, 2%, 2%, 4%.

well i have 1 10an line coming out of the back of my valve cover and i have absolutely no oil residue from the line, and i am boosting 18 psi, that creats a lot of crankcase pressure. but i guees all setups are different.

It could also be how the cars are used. I doubt you're running your car at WOT 95% of the time. My car doesn't see much partial throttle use.

Thanks for the help and advice all. I am going to fill the catch can right up so there are no big spaces, it makes sense in order to catch as much of the pcv oil vapour as possible.

i would try and stay away from wool and use scotchbright type of stuff instead. just cut it into small cube/squares and pack the can full of it.
