Spark Plugs & Oil Leaks

Video Transcript

"Hi, I'm John with ExpertVillage.com and we're changing spark plugs. We're talking now about what we can learn from our about what's going on inside our engine from our spark plugs. And we talked about some of the things, if it's warm and there's carbon deposits, ash deposits. And we also talked about what it should look like. Let's talk some more. Now if there's oil deposits, it'll just be coated with oil. That can be an oil leak inside there. That'll tell you that you need to do something with your engine. That can be hard to start, there be misfiring and hesitation. So you need to go take it to a mechanic, or do it yourself. If there's, now right here the gap right there, that's where the spark jumps in between these electrodes. Now if it's connected because there's so much deposits, that can tell you that there's just too much deposits accumulating inside there causing a gap. And that can result in a dead cylinder. Because if there's no gap, it's not going to fire. So if it's misfiring, that could be one of the things."
