where does this hose go to???
The hose comes from the back of the intake manifold/OSV area connected to this cylindrical funnel and tucks in the passenger rear corner of the engine. Can this hose be accessed some other way? There is like no room back there. Thanks. ![]()

Not definite, but think it is one of the drains that goes back to the oil pan

Oh yeah....looks like it's connected to the oil return pipe.
Any tips on accessing it?

The funnel-looking thing is the oil separator and that hose is the return line as posted above. You've got as much room as you ever will with the intake removed. Take off the cabin air filter housing if you haven't already. It is possible. I've even replaced the metal oil return line with this amount of access.

I was thinking about removing the whole return line from the oil pan...but then I have to drain all the oil again since I barely changed the oil just 2 weeks ago.

Drain it into a clean container and reuse it.

Replacing that whole mess (CCV valve integrated into the rear intake cover, oil separator, hoses, etc) frequently is really important if you live somewhere where it freezes and if you don't drive long distances daily to remove water from the crank case. But it looks like you live somewhere warm.
I did replace the metal line as I discovered the smaller vent side was completely occluded with gunk after I had the classic frozen CCV - sucking oil - billowing smoke problem.

Ok, if you look at the diagram. You can see where to two hoses go. Now I will tell you. The two hoses are difficult to access. Even pulling the metal tube is a chore, but can be done. So pick your poison. Those hoses allow the oil vapor to collect in the CCV, funnel down and the hoses bring the oil back into the case. Make sure to replace the two breather hoses that cross each other in the back of the intake as well.
