GM OEM catch can?
I noticed that Lingenfelter is selling an oil-air vapor separator.
It looks like an OEM part.
I think I also read something about the Cadillac supercharged CTS-V having something like this from the factory.
Anyone know about this? Pretty expensive for a catch can, but looks impressive.

An after market black catch can with black hoses (from vendor of your choice) will look oem to 99% of the people who see them.
On a side note, Cadillac is supposed to be coming out with a two door coupe in the CTS-V very soon...about the time my wife needs to replace her Trailblazer, hopefully.

Dang, Hotwheels - you are one rich dude!
Regarding OEM air/oil separators: car manufacturers are working on this issue; currently, some form of impaction geometry is used to separate oil droplets, collect and allow the oil to drain back to the oil pan. I believe that the last thing they want to add to an engine bay is another thing that requires maintenance.
Keep in mind that while this is a very difficult problem to eliminate, the effects are typically felt long after the engine warranty has expired.

Unfortunately, there is only one testing company in the US that does testing as per SAE standards. Their comparison test runs into the thousands of dollars and few catch can designers (like myself) would pay that much money to get definitive results. Therefore, it makes sense to know how a particular company is separating the oil. Many completely seal their units; not only can you NOT replace any filtering media inside, but when it does everntually get very dirty, you must toss the entire unit away.

Thanks for the comments. I tried one of the favorite Forum cans, and saw only 2 results:
It caught only about 1/2 ounce of oil in 5K miles, and most of that leaked out the bottom through an improperly threaded cap. Sent it back for a replacement, and got the same problem again.
So, the idea of a factory-looking piece , with an impressive, cleanable filter, looked pretty cool; but maybe not $200 cool- Ha.
They think the new CTS-V coupe will be in the $70k range. That sounds awefully good compared to $110k for the pimped-up carbon fiber ZR1.
Oh, driving a loaner CTS this week while the CaddyWagon SRX is in the shop. The CTS has to be the finest American sedan I have ever driven. No, it's not up to German standards, but it fares very, very well with anything under $50k.

You can see my thoughts on the various designs of catch cans here:

The catch can comparison part starts about a third of the way down. I've worked with o-ring and gasket designs for many years - thus the comments about sealing designs.
The CTS is an engineering achievement of significant proportions. However, reliability has been sub-par. Mercedes and Audi suffer the same category of gremlins - primarily electronic and electrical in nature.
