well i was tearing it down today and have a question about the oil injector lines,

1 how in the hell do i get them off

and 2 once you have figured out how to get them off how do you do it without breaking the brittle pieces of ****.

aside from that and about a million other brittle and broken vacum lines i am doing jsut great

 

TTT

 

I'm doing a teardown as well, all 4 of mine broke off-- I'm thinking it's going to have to be a Mazdatrix item, unless anyone else has used something different.

I know you can get rid of them and run premix, but that's not right for me-- need to retain the omp and lines.

You can take them off with a thin 14 mm or 9/16 open end wrench. Before you start to loosen them, just make sure to hold the metal part where the oil line is attached (I used a pair of pliers)and DON'T let it move while you unloosen the injector. I took all four off without breaking any doing it this way. If the lines move any at all, they most likely will snap.
hope this helps!

 

If they're that brittle, prolly should get a new set from Mazdatrix. Mine were toast.

snapped all 4 of mine as well..

 

on the fd metering lines we see that the crimp between the line and the banjo fitting is bad, its cheap insurance to just replace all the lines. that way the chances of you breaking the line putting the car back together are lower

I had to take a 14 mm wrench to a machine shop. They ground the head down thin enough to get the lines off. I'm with everyone else here. I you are doing a rebuild replace those lines with new ones from Mazda!

sounds like a good plan,,how much are the ones from MazdaTrix?

 

i think they're about 20 - 25 a piece

 

There is a SAE and METRIC solution.

Box end wrenchs will take them off.

I always replace the oil lines.

I dont know why any grinding of anything was required.

Make sure you clean the injectors with carb cleaner.

The lube them with wd40.

Then put a hose on the injectors and check that you can blow air, and none should be able to go backwards.

 

It is very wise to replace the lines. It is cheap (not really) insurance to know that they will not leak in the future. Or, crack on you when you put them back on....it had happened to me.

If you are successful on removing them w/o breaking them, replace the copper crush washers. Second, torque to spec the bolt to the OMP. Third, cover the lines w/ heat shelding...it keeps them from becoming brittle.

Happy rebuilding.....
