Question about 1991 Mazda 929
This problem is causing the engine to run rough and consume gas at an alarming rate.
I doubt the gasket is the entire problem
Why wouldn't you replace the valve cover
gasket,then explain the driveability ones?

It will not go off by itself,you will need to reset it by connecting to a diagnostic tool.Once cleared if there is any other problem then it will trigger the check engine light again.Hope this helps..

just look at the valve covers some are held in place with 6 bolts some only 3 do one at a time and keep working area clean and free of dirt n grease. clean valve cover good and have clean hands when handling gasket, and there your done just replace and bolt down , check bolts again for tightness in a couple weeks.
