I own a rx71991 convertible non tubo. I just checked the omp and am getting 1-2 cc of oil out of the two front lines when running at 200rpm for 10 minutes with premix. the unit is electronic. Is there a rebuild kit available? Any way to make it put out more oil? Book says take it to Mazda. I gotten several ests from them on other parts and am not thrilled with their prices. Is premix the answer? Any suggestions? Thanks for any help you can give.
