Someone removed my vacuum lines on my 98 xj8, Could someone please tell me the routing from reservior tank to engine and over to control valves. I need a good detailed description. I have check the factory CD's i own, but have found nothing. Thanks

 

There is a hose from the coolant reservoir back to the thermostat tower for vacuum return of the coolant as the engine cools. There is a second connection on the reservoir that is not open and is not used.

The only other vacuum line is from the part load breather orifice, on the forward of the left valve cover back to the throttle body.

What 'control valves' are you referring to?

 

Is this what you are looking for?

 

*****:
I hope it was just a matter of semantics, but there are vacuum lines and coolant bleed and vent lines that look the same on an XJ8. Be sure you make no connection between them. You are talking about the small lines that connect to the colling system, right? They are not engine vacuum lines.

 

I am referring to the engine vacuum lines starting at vacuum reserve tank below the air box and continuing around to valves below driver side panel(next to master cylinder. Thanks

 

Merry XMAS,
I HAVE A PICTURE HERE ITS NOT THE BEST EXAMPLE BUT I was wondering if you can help me out by were this vacuum line goes to or even if it is a (v.line?)
I HAVE BEEN EXPERIENCING OBD II CODE P0174..AND I CAME ACROSS THIS CUT LINE...

THANK YOU JF AND HAPPY HOLIDAYS

 

Did you ever find out what that is for? It seems to me it is some sort of rubber plug...

 

I seem to remember that it is a VENT to the motor housing.
