oil metering lines positions at pump
 

Which line connects on top at the pump, the line from the 1st rotor nozzle or the line from the 2nd rotor nozzle?

thanks for the help

the orientation does not matter as both receive oil.

if you were to go by the book the refer to attachment. logically it will drip oil in same quantities into each chamber.

Unless you are doing your own lines, only one line will most likely reach to the 2nd rotor housing.

I have the correct connections at the nozzle ends. I am concerned if there is a proper orientation at the pump side. In other words does the 1st rotor line connect to the top orifice of the metering pump. Or does it matter? I assume the metering pump injects the oil in synch with each rotor during some time in its combustion cycle.

It doesn't matter, but like I said, you'll probably find that the lines will only confortably reach to certain connections.

thanks Mahjik and all the rest of you guys. I appreciate the responses.

I just wanted to be certain it does not matter.

So I have a question about the oil metering lines. I've been doing some major reconstruction on my FD lately and I ran into a little snag. It seems that I snapped my oil metering line to the rear rotor. I know I need to fix it, I was just wondering how I could do that safely.

Has anyone ever done this before? I'm sure that's a stupid question considering how brittle that thing was. Any guidance I could get would really help me out. Thanks,
Jeremy

you probably dont want to re-use oil lines that snap that easily. Just buy nice new steel braded lines. I bought some from rx7store.net.

Do you mean these:

I'm not sure if we're talking about the same thing. I mean the little plastic line that runs around the primary injectors to the rear rotor. It sorta makes an upside down "U" if you're looking at it from the passenger side. It's very small, maybe 3 or 4 mm wide plastic and very brittle.

Thanks,

Jeremy,

The stock oil injection lines are clear plastic. Over time, they get brittle from the underhood temps and can snap VERY easily. A few shops are now offering SS lines as a replacement for those.

You can see them in the picture from the following link:

That was a friends Mazda reman we were setting up and he used the SS lines instead of the stock plastic ones. I also used them as well on my rebuild. However, replacing the lines while the engine is in the car is not fun. What you "could" do to get by is to go to your local NAPA or AutoZone and find some tubbing rated for oil. Then just connect up the two sections which broke.

So those are the lines that the rx7store is selling? I've got everything out of the engine bay including the turbos, IC, battery and alternator. I think I can get to where they connect. If those are the right lines, I'll order them today and get them installed.

Thanks guys,
Jeremy

yes, those are the lines. the stock lines are of very poor design as you have found out. the ss lines are a worthy upgrade as long as it is easily accessable.

So I ordered them. Anything I should know about the installation before I attempt it?

Thanks again for all your help. I'd be lost without you guys. :dunno:
