42 Draft Design Stealth oil catch can installation

[Gt4]

So I bought a 42 Draft Design Stealth oil catch can in wrinkle black powdercoat and installed it were the emission control air pump usually goes. I made a custom bracket and different hose routing on the top of the coil cover. I also painted in black the aluminum shield protector on the headers.

Here is how it look:

Nice and clean. Good job!

Very nice. Do you have a parts list? It looks stock which will help with the emissions folks in california.

For some of the newbies, you might want to explain the benefits for them.

best CC out imo.... simply stunning in form and function....

i love your mouting point to, its perfect!! i used some of the old s/c "ribs" to make a bracket..... i went for the unit with the dipstick

Looks great and very stock to the untrained eye! I have used 42DD products on my Audi TT and have always been satisfied with their quality.

What is an oil catch can?

An oil catch can is used in turbo applications, or high-performance race applications where excessive blow-by (leakage past the piston rings) of air and fuel vapor occurs. This creates a positive pressure in the crankcase. Engine manufactures have placed a valve on the engine block which releases this pressure. This valve is known as a PCV (Positive Crankcase Ventilation) valve. During engine operation, blow-by gases, as well as oil mist from the rotating components of the engine, pass through the PCV valve and are routed back into the intake for the engine to burn off. However, some of the oil mist and other products settle along the engine intake and over time form a "gunk." The oil catch can collects the oil mist and condenses the fuel vapors while allowing "cleaner" gases to be passed back into the intake. Typically the blow-by gasses are passed through a wire mesh, which give the vapor droplets something to adhere to. Since the oil catch cans condense the vapor portion of the gasses, they will need to be drained periodically of all the oil, fuel and other contaminants.

I TIG welded the bracket from 1''x1/8'' flat bar and used a break to make the 90 degrees angle.

You need 3/4 hose or AN-12 to fit the 42DD oil catch can nipples but you can use 5/8 hoses or AN-10 like me and just stretch it. The fitting on the coil cover fit well with 5/8 hose. No need for Tridon clamp, I am just extra preventive

If you want to get rid of the plastic hose on the top of the coil cover and be able to rotate like I did, just cut it and put a 1/2 rubber hose with clamps instead.

It's really easy to do. Just figure out the way you will do your bracket if you still have the EGR pump and the rest is super easy.

And essentially raising the octane level, since it is not diluted----from my understanding. I might have to copy this. Great job.
