Oil Catch Can Set-up
#22
Thanks for the pics! I guess they changed things around in 08. My PCV comes off the oil fill tube on the passanger side of the engine bay. Its a little crammed over there so Im going to have fun finding a spot for it. I was going to put it on tonight but I need to get a fitting to adapt the hoses to the right sizes. I did get the breather installed though.

Here's how a baffled (vented) catch can works. This is not to scale, but you get the general idea.

Thanks donkeypunch. You could use that on our breather hoses, but on the PCV system that would just create a huge vacuum leak. I had to take my can yesterday and put some RTV around the nozzels so they would be air tight. They couldnt hold any pressure. Anything on the PCV system has to be air tight and able to hold vacuum, and boost if you have it.

Not that I am aware of. Unless I am missing something, you should be able to run a hose from the valve cover to the vented catch can, and cap off the hose barb that is located on the intake (where ever the PCV valve plumbs to). This is the setup I have on the Talon. Or you can run a sealed can that seperates the air and oil (but then you get hot air that goes into the intake).

Heres my catch can. I got it all set up and ready to go. I hooked it up for a minute, but Im still questioning whether or not it will be able to handle the pressure from the vacuum. Im going to try and figure out a way to pressure test it, becaues the last thing I want is a vacuum leak. It couldnt hold any pressure when I first got it, but I sealed up the connections on the can with rtv sealant. But in the picture, the hose facing towards the can connects to the PCV valve, and the hose facing away from the can connects to the vacuum hose. With the adapters I made up, no modifications have to be made to the truck. Just remove the current hose and tighten up a couple clamps. I did install it on the truck and ran it for a minute, but then took it off. I plan on mounting it on the side of the fan shroud.
