Apologies if you guys have already covered this, but I have a similar problem... oil pool under the oil injector closest to front of engine.. oil evident on spider junction of vacuum lines and possibly unrelated but leaking oil return flange on turbo

One thing that really confuses me is that my mechanic has ran the main vacuum line from the outlet of the turbo to the oil injectors! Is this right??

Really over this problem with my FD!

More and more, it sounds like Mazda got a new supplier for the nozzles, and they are junk. Here's what I did to replace them. I'll start looking at ways to produce in bulk:

If I'm understanding correctly, the vacuum line is after the turbo, so its seeing boost? It should be vacuum only.

Stock the vacuum lines on top of the OMP nozzles go to the turbo INLET.

The inlet is ATMOSPHERIC PRESSURE, not vacuum.

Basically it's just a source of filtered air from the air box. That's it.
