Question about 1989 Honda Civic
Hello there you asked for a little more information on the smoke. Well it has not been overheating or losing coolant it was just running poorly and loud. The smoke only started after he changed the spark plug to a new one. He did show me oil on the spark plug the ols and new one as well. he said that the smoke was from all the oil that been backed up into the cylinder? he said it had all been caused from autolite spark plugs he said they probably lasted me a month so can a car run on bad spark plugs and is there special ones for foreighn cars I just feel that since my car was still driving that I didnt need a new motor but he said that once he put new spark plugs if it keeps smoking that means i need a new motor
Well some spark plugs are better than others for certain cars and Autolite plugs are not recommended for hondas. As far as oil showing on the plugs the more likely indication is that the valve guides have gone bad on the engine. A good sign of bad valve guides is if the car smokes more when you first start it after it has been sitting overnight. The Proper way to test for a sound engine is to do a compression test on the cylinders, that way you have a percise check on the overall health of the engine(for a mechanic to say otherwise is not a good sigh). If the car does have bad valve guides it is not threatening to the healh of the engine. You biggest problem from faulty guides is that it will cause you spark plugs to foul(oil soaked) and not fire as well as it should, In my opinion and without having the results of a compression test I think that valve guides is you proplem and not a "bad engine". The reason for your car smoking more after the new plugs is that they are able to burn the oil and you older autolites could not. My biggest and most important recommendation is that you never go back to that mechanic again.
