It's a pump that meters oil. . .



Yeah it's the pump that squirts oil into the rotors. You have a check engine light so I'm guessing S5.



Probably going to have to go to Mazdatrix or the like, that or get one used...

It's somewhat like 2 stroke oil injection... the OMP shoots a given amount of oil (through the oil injectors) onto the rotors, the amount of oil it pumps is based on RPM.

I hope you're not driving the car around with that thing broken. If you have to, in the meantime premix some tcw-3 2 cycle oil in with your gas.

89-92 are all the same oil metering pumps, and $100 dollars is a steal, they usually retail for over $1000 dollars.
