As some of you know, I’m on my second Y34. On the first one, a few years back I had added a catch can to keep oil from entering the intake from the PCV system. It was somewhat successful. There's a link at the top of this thread to the write up I did back then.
The 2nd Y34 is in need of a solution as it is burning oil from the same bad PCV design.
I want to do something different this time.
I bought a new PCV valve from AutoZone. I plan to remove the original, drill out the insides and replace it.
After the drilled out PCV valve is replaced, it will be followed by a container, followed by a properly working PCV, then to the intake. (Short tubing pieces to connect it all.)
I can find a cylinder, maybe 50 cent piece in diameter, loosely fill it with steel wool and let the oil laden vapor go through that first & separate the oil out before it goes to the working PVC valve, then the intake. I’m thinking clear would be best…
Oil is allowed to drain back into the valve cover through the drilled out PCV when crankcase pressure is low …instead of into a catch can that always needs to be emptied or fills and becomes useless.
My alternative is a container with drain plumbed through the dipstick tube but I’m not sure how I’ll plumb that.
What clear tube container do you think I can use for this?
