Anyone have a OBD1 S52 Hose diagram for manifold?

Ok so I am buttoning up the OBD1 S52, under the manifold I am getting a little confused about what goes where, and what should be there. Does anyone have a good diagram or something to put me on the right track? Any help is appreciated.

Vacuum? Coolant?

If you check out realOEM it makes it pretty simple.

The PCV vacuum goes to the connector on the back of the manifold where the hose coming out of hte ICV connects in. The FPR vacuum hose goes to the little nipple by the IAT sensor. The vacuum connection on the throttle body is what comes from your EVAP valve/charcoal canister.

I am having a hard time figuring out the crank case vent setup and do I need to use the S52 cone shaped filter under the manifold, sorry I am getting all jumblywumbly

You're using an OBD1 manifold? If it were my swap, I'd route the hose from the valvecover to the throttle body boot. You'll need an OBD1 non-ASC boot, off of an early M50TU or M50(NV) would work fine.

Thats what I am thinking, I have a bimmerworld silicone boot, isnt there a little valve that goes on the crancase on a obd1?

Yup, PCV valve. Then there will be two hoses off of it. The small one goes to the connector on the intake manifold where the ICV hoses connects to. The big hose goes to the intake boot. Or you can be balla and run a catch can inline from the big hose.

The other hole in the intake boot is for the hose that connects to the ICV.

Got it, had to order the little pcv valve, thanks Z31. Oh yeah the two ports on the E34 dipstick, anything attach to those or do they just get blocked off?
