Apparently I have a little oil leak. Can someone advise me what part of the engine this is? Maybe this is common, I don't know.

Yep. I hope you're still getting the proper amount of oil injection?

Dysfnctnl85

How would I know that?

You may just need a new o-ring for it.

or

get a block off plate, remove the lines and run premix

As per FSM, you're suppost to remove the oil injectors, set them up over a small cup, and run the car for a short period of time and then measure how much oil is in the cup. Somehow that test makes me nervous.



The only thing that doesn't make me nervous is ditching it and running premix.

I was worried about mine because it has leaked small amounts of oil ever since i got the car...but i've been told those oil injectors leak even if you buy a new one...or rebuild it...might try replacing the lines tho...mazdatrix sells them for about 15 each i think...



from what i understand theres really not much in there...a "piston" which is actually about the size of a pin...and some seals...plus i've been told that they almost never go bad



so unless your hoses are getting brittle i wouldn't worry about it

Would a grommet or something like that not keep the oil from leaking?

from what i understand...no...they just leak...no matter if you rebuild them or not...its just something to do with the design...but it probably wouldn't be a bad idea to rebuild it...since it supplys oil to your almost or over 20 year old engine...shouldn't set you back too much since its only a few parts and some seals...and it beats buying one new...cuz i'm pretty sure they're around 150 bucks from mazdatrix
