Anybody ever heard of or use a Walker Airsep oil seperator system ?

I have one on order for three months, still waiting for them to make it for the third gen motors.

First of all, how will it make your engine run on vacuum?

HELPS KEEP COMPRESSOR VANES CLEAN??? Are they serious? If your engine is an open crankvent system now (as in the crankcase gases are totally exited to atmosphere) there is no compressure vane conatmination. I don't care how much you filter the gases with an impactor. You'll get more soot on the compressor than an open crank vent system that doesn't even plug into the compressor at all.

Same goes with the intercooler.

If they could actually filter all of the oil out, than that would be good, but its pretty much impossible to get ALL of the oil out of the blowby gasses.

I can't believe they get away with that marketing.

 

..."The Airsep® reduces crankcase pressure, causing the engine to operate in a vacuum."

easily... a venturi effect causes a low pressure... the engine i work on run the crankcase at low pressure [0 to -10"h2o negitive pressure] but the system is plumbed differently.. the ones at work have a venturi device mounted in the exhaust stack, and some also have a pressure line from the air box after the turbocharger blowing across another venturi after the oil separator...

i have plans for running something similar, but using the racor version of the crankcase vent and plumbing it into the exhaust stream to extract the vapours and run the crankcase at a low vacuum [±-5"h2o]. i don't want to risk getting oil into the charge air cooler..

 

I spoke with Airsep this spring. I was talking to them about a cure for the fumes in the winter after my extended breather hose froze up. They told me they would be in touch to have one on my truck and have it work with my intake.

Not a word since.

Where can I find this Racor idea? I think it might be the way to go.

it will require fabrication of your own doing to make a working item...

the racor crankcase filter i am thinking of.. it basically is a standard closed crankcase vent item like the airsep but instead of the one end being plumbed into the air intake to burn the vapours and potentially fill the CAC with oil, i would put a venturi generator in the exhaust stream [end of downpipe maybe?] and plumb that to the filter to use the exhaust velocity to create the low pressure and vent the fumes out the tailpipe..

the racor i was thinking of using was one of these...

ccv line into exhaust here ^


something like above plumbed into exhaust with flow going >>>>>>>

 

That looks like a great solution. Would it be a good idea to eliminate the little filter element on top of the valve cover? Last time I checked mine it was oozing with oil.

Thanks for the info!

my idea for using this is with plans on using an aluminum valve cover off a marine isbe i believe [if you search the tdr, under products/accessories -engine/drivetrain - 3rd gen valve cover revisited] as it doesn't have a breather on it like ours, there is some baffeling under the cover, but i don't know how well it will separate the free oil from the vapour...

 

So any word on a Walker AirSep for the 3rd gen Cummins????????

 

any luck?
im interested

 

I am a diesel mechanic for the navy, and we use them on diesel generators. If you keep the oil separator clean, it works very well. You just have to use gas about 2x a year to clean the oil out. It doesn't work on venturi principle. The crankcase vent is routed between the air filter and the turbocharger. Whatever your turbocharger differential pressure is, will be your crankcase pressure (vacuum), assuming your blowby isn't high enough to restrict flow. The oil that gets through is a vapor. The oil that can be condensed to a liquid, will be, and is drained back to the crankcase. Sorry I can't help you third gen guys. If you just get a oil separator, you can plumb it into the air box after the filter, and work it out for yourself. the turbo stays pretty clean though. hope this helps
