If you have a build up of pressure in the crankcase from turbocharging the engine then your rings are not sealing correctly. Go to a good workshop and get a leakdown test done to confirm. The only other way to increase crankcase pressure is for PCV valve to block up. The pcv valve is found on the cylinder head on the inlet side on a NB8B. If you blow through it air should pass freely in one direction only, sometimes the ball valve sticks and blocks.

Where is it leaking oil?
A standard NA6 has a rubber hose on the exhaust side of the valve cover than attaches to a chrome pipe that runs around to the front of the engine and connects to the inlet pipe. You should attach an oil catch can to where that hose attaches to the valve cover.
I have read on miataturbo net that for FI cars it is recommended that you replace the Positive Crankcase Ventlation (PCV) valve with one from a GTX (factory turbo), which I need to do myself.....not sure where to get one though...wonder if one from a SE or SP would do the job.

Do a search on PCV valve.

Buy it at a mazda/ford dealer. Less than $30. Looks no different to the standard one.

Actually the FM one (and possibly the SE one) have a larger spring to compensate for the additional pressure from the turbo.

Oh, in case you are wondering if a stronger PCV valve is the way to go check this out.
