Broken coolant neck and unknown vacuum lines

[MrTalmus]

Hi guys,

It's been a long time, over a year to be exact, when I wrote this article about some broken rockerarms. (https://zilvia.net/f/showthread.php?t=660144)

I've finally put the engine back together and it seem to run perfectly, problem is tho that the coolant neck is broken and I've already planned an inspection to get the car roadlegal and have a very limited time and therefor don't have time to order any parts.

I do have a coolant neck without the tapped input for the turbo coolant return. Is there any other places I can put this turbo coolant line or do I really need to order a new part?

Also, there are two inputs/outputs to the "throttle body" or the secound part of the intake that is connected to the head. which I don't know what I'm suppose to put on, I do have one vacuum line which I'm pretty sure has to go on one of these inputs, but I don't know which of them and I don't know where the other line could be, so my question is then what are those two inputs for and what kind of line's are suppose to be on them? Knowing what they are for and what to put on them would help me locate the
appropriate "hoses". I'll be posting some pictures. The line I'm holding on the picture (#3) is going inside the car.

I hope I can make myself understood as English is not my first language and technical words don't come natural to me.
