HAHA...another entrepreneurial spirit at work. I though about this at one time for my other cars to minimize the need to periodically cleaning out the TB.

It looks like a simple air compressor inline filter being utilized in a different fashion.

Great! Now your Porsche can be outfitted just like a Harley Davidson engine!!

 

I'm not the seller, saw this while I was TROLLing CL.

 

Will this work with both 0W-40 and 5W-50 Oil?

 

Oil Catch Can

 

Interesting Mike. How does it work? Can you post more pictures?

Cheers,

I wonder how it works as well.

I know there is a minimum amount of oil getting into the intake manifold, but is there really a need for a catch can ?

This oil in my catch can is about 130 miles of driving, maybe 20% of it is high RPM.
1 important thing to remember on catch can is you have to empty them often. Ive seen a 993 catch fire because of that.

 

+1 for catch cans

I'm currently building a system for an LS1 (more clean than OE routing).

 

That is a really nice/small can - what brand/model is it?

Thanks.

There's nothing complicated about how it works - it just goes inline, allowing vaporized oil from crank case gas to be captured prior to getting sucked into the manifold.

If you're so inclined, you can make one of your own out of just about anything that doesn't catch fire and doesn't react to oil... just ensure it seals well, and like Mike said, empty it on occasion.

By the way, loads of people have used a little compressor drier you can buy at Home Depot as a catch can. It looks really really cool, but the acrylic apparently reacts to the oil and eventually breaks. I mention this only because if you're intersted enough to Google catch cans, you're likely to run into that pervasive "mod."

Yup I was looking for a small can since we dont have much room in our engine bays.

 

I'm not a fan of catch cans for they add complexity to a street engine that does not have a corresponding additional benefit.

But your post, your pics, do tend to reinforce my belief that in some cases "high oil consumption" is not a engine problem per se but related to the amount of oil the AOS fails to remove from the crankcase vapor that is routed to the intake manifold.

 

In the old days the oil was simply dropped onto the road beneath the engine. With tightening emmisions in the 60's the Feds required the oil to be sucked back into the engine/intake. Catch cans have been around for a long time as a way to get around this.
