What I really need is to change the oil lines from all injectors. Do I need to remove the whole injector? Or just a nut? I canīt get a wrench on the nut shapped area...What size is it? Thanks for any responses.

 

14mm, i believe, tho i couldn't get it on the injectors on the block...i think the wrench was too tall.. :-/ I could get the manifold oil injectors out with the wrench. For the block ones, I took a pair of pliars and broke them loose, and unscrewed them by hand.. Just don't squeeze it too hard, and you should be okay.. You'll need new copper washers, but they should be like a dime a piece at the local auto store.. bring in an old washer for reference.

The injector is essentially a banjo bolt. 10mm x 1.25, i believe.. there's a thread called "omp vs premix", started by RX-7 GT, that discusses completely removing these, and running premix... read that one to see if that's good for you.

I had the same problem. You need a 14mm wrench that is thin enough to get in there. I took mine to a machine shop and had them grind the head down thin enough to get in there. It cost about $10.00 to have them grind the wrench down.
