I didn't get a response in older related thread, so I will try again.
I have two different catch cans connected sequentially in my Tahoe. That works well, but now I'd like a catch can in our Mazda, and I will transfer this setup there.
I am thinking about building a large catch can out of 3 or 4" DWV copper pipe, with copper tube going almost all the way to the bottom, and steel wool in the middle. Maybe even the accending spiral out of steel wool. I think copper will work better then PVC water pipe for heat transfer.
I don't have space constraints under the hood of Tahoe for this purpose. Maybe I will even place it under the bumper cover or in the wheel well.
My question is about copper as a suitable material. Is it acceptable for that application? Would the metal react in some way with catched stuff that would produce some chemicals detrimental to the engine internals? Would copper corrode in contact with steel wool and caught water?
Maybe stainless exhaust flex pipe or straight tubing will work better? Thick walls though...
Also, would PVC clear vacuum hose work PCV with gases? Thinking about 3/4 ID hoses to lessen restriction...
Thank you for your help!
