Just an update on the 2016 Explorer Sport....
I got the OCC setup completely installed. Only had to drill one hole / "tap into" the pipe that leads to the rear turbo. (never figured out what that aluminum connector adapter was for)
I installed the OCC on the DS frame horn behind the headlight. Ran the hoses from there under the air filter box along the turbo tubes and to their appropriate locations.
Once all back together all you can see is the one hose at the rear turbo tube / tap and the one hose to the CSS / oil cap looks a little different from stock.
To drain it all I have to do is lay on the ground, reach up into the DS front portion of the fenderwell, pull out the hose, insert into the appropriate container and open the drain petcock.
Now to see what it captures.
I've been running an OCC on my 5.4 S/C truck for ten plus years now and I know these OCC's work.
*edit* One thing not seen are the 2 check valves... I installed the hoses first and then selected and "cut in" where I wanted them. The one for the turbos is mounted down by the transmission dipstick / front turbo tube and the one to the manifold vacuum is up on top of the engine near the PCV valve.
