Question about 1991 Mazda MX-5
91 eunos roadster smokey start up in morn for a few mins then clears same at night when i leave it for the day at work
Shot in the dark but could be 2 problems. Leaky valve cover gasket- my spark plug holes used to fill up with oil before I replaced the gasket. Plus loose or cross threaded spark plug. The oil would be constantly leaking into the engine and would burn off and produce smoke. The leak is small enough that there is no noticeable smoke while it is constantly burning the drip off. When you park it for awhile the drip adds up to enough oil in the engine to see smoke. With plugs in place, stick a paper towel down in the spark plug holes and see if it comes out dripping with oil. If it does, see if they are all tight. if they are, check your threads for damage or any other way the oil could leak into engine. I am not a mechanic but I did have a lot of smoke at startup after I pulled a plug, forgetting that the hole was filled with oil from a leaky gasket.
