I have installed new oil lines from the oil meter pump to the oil nozzles in a 86 RX-7 13B non-turbo. This thing had a small engine fire and I have a lot of vacuum hoses to replace, which I have a diagram to follow in the Hanes manual. My problem is that I can find no documentation as to where the hoses that attach to the tops of the oil nozzles go. Please help! Pictures or diagrams would be a big help as well, because I really don’t know the names of much of these parts.

 

Coming out of each of the top of the oil injectors is a vacuum tube (which you know), all four oil injector's vacuum tubes connect to a "Distrobution block" vacuum block (it converts 1 line into 4). These are availible at any auto parts store. The one line from the distro block then goes into the big vacuum connector on the front side of the throttle body (or any other vacuum connection you like). Unfortunately, I don't have pictures, but there's not really much to show. 4 vacuum lines to the 4-to-1 adapter, then that one line goes into the throttlebody somewhere.

hope this helps

 

Was that 4 into 1 distribution block plastic? I dont see it anymore
There was a big pile of burnt plastic and rubber down there when I got to it..

Thanks for the help

 

yes, yes it was

 

ok, well now if I can get the idots at auto zone or pep boys to understand what Im talking about, they keep saying "well, I would just call the dealer"

morons

 

eh, just look in the vacuum supply rack.. . there's one there right next to the vacuum tubes. It'ss erioulsy just a 4 port connection on one side and a 1 port connection on the other can't miss it.

 

The vacumn line from the 4 into 1 connector goes to the top large vacumn nipple of the three that are in a line on the front of upper intake manifold. It supplys the metered air that goes to the oil injectors. The middle nipple is connected to the vacumn nipple just to the passenger side of the primary injector ports on the lower intake manifold, you can see it in your picture of the oil injectors. The bottom nipple is connected to a vacumn line with an open end a part of the rats nest. It is located towards the drivers side, about an inch, just below where the three in line nipples are when the upper intake manifold is installed

 

yuck!


the mazda pulsation damper strikes again!!


you may have to get the geeks behind the counter to open a book for the vaccum "tee", i doubt all auto parts stores stock a 4 into 1 vacuum tee but i am quite sure they can get you one. it looks like a standard vacuum tee but has 4 nipples on one side and 1 on the vacuum side. tell them "it looks like a cows udder" and i'm sure the backwoods parts guys will pull one out of the drawer for you.

 

Thanks for all your help!
Ill keep you posted on my progress
