Oil drain hose under intake manifold?

[Heckler]

I removed my intake today to do the valley pan and when I pulled the intake up the oil drain hose that connects to it was totally rotten and just fell apart, my question is where is the other end of it? Im trying to order a new one but cant find it anywhere on RealOEM. Thanks

That hose goes from Oil Separator (BMW's term for PCV valve) and the
base of the dipstick tube.
Mine rotted off completely about the 200K mark. Pretty easy to replace
if you don't have to do the Oil Separator. Now that one is a #$#$#!

So the hose under the intake goes to the Oil Separator? I have the Oil Separator out but like every other hose the bottom one was so far gone that it wasnt even connected anymore, is that where the hose from the bottom of the manifold goes?

There are several hoses. There is one that comes off of the OS to the
dipstick. Mine rotted off. The replacement has more insulation as it is
near the motor. The other ones go into the motor.

# 4 is the flexible rubber hose to dipstick.

The others are molded stiff plastic. Kind of pain in the #$#$# to snake
around and connect.

I have a 4.4 V8, guess thats where the confusion is. The hose Im talking about is under the intake manifold, you cant even see it until you remove the manifold.

Yes, there is a difference. I think you have to deal with the motor next to the firewall. That is the reason to take off intake manifold.

Im doing the valley pan so thats why I removed the intake, that hose connected under the intaks just fell apart and I cant find in the TIS or Real-OEM where it goes, there is nothing left of it.
