Question about Mazda B2300
I took the spark plug out after several years of it being there. It stayed in there probably 5-7 times as long as it should have. It unscrewed ok, but the new plug which is same brand and type, won't go in. It gets started ok, but after about 3 rotations it stops hard like it doesn't want to thread in. I am tightening it with my hand pressure using a long necked extender attached to the spark plug, not the wrench. I twist left a few turns to backthread it, then i twist clock-wise to tighten it. Tomorrow I am buying another of the same spark plug to make sure it's not the plug. What could I be doing wrong? Is there some kind of threader liquid I could pour on the threads? What's the worst that can happen if the threads are cross-threaded? Could Mazda or myself fix that sort of problem? Thanks for reading. Rob
You can put a little bit of oil on the treads to get it started. Do not cross tread it because it will strip the hole out and you will have to replace everything.
