Yorks run their own oil sump that lubricates the piston, if the rings are still good should have minimal oil going into the air lines, there are also mods that can be done to them that reduce it even further.
I have never actually used one in an airbagged car but have bought and sold maybe 30-40 of them over the years to minitruckers and offroading people.
They are quite cool wee things, can pump like 18CFM at redline and have an electric clutch so can disengage them when not in use.
