What's causing my honda accord 1998 spark plugs to burn out so quickly?
The plus becomes black at the first start. There's oil in btn the engine cover n the engine. But the burned out plugs oily.
Black soot on the porcelain and electrodes in the combustion chamber is a sign of a rich mixture. If you're saying you've got oil leaking down the spark plug tubes, then you must replace the valve cover gasket and spark plug tube seals.
Plugs aren't burned out because they are black. Plugs erode as they wear, erosion determines replacement, not color. Agree with stpaulguy. Black is either way too rich, or burning oil.
Please tell me this thing doesn't have a stupid air intake and fat exhaust on it. Those can exacerbate plug issues.
While your at the parts store for the valve cover gaskets get a air filter.
- Spark plugs covered with oil plus exhaust smoke? Just got the carbs cleaned and working perfectly on my 82 Honda Nighthawk 450. I started the bike and just a moment later there's a white smoke coming from the engine and exhaust. I took the spark plugs off to aid in addressing the issue and I have found that there's a black oil on them. Anybody have an idea as to what's going on here?
- How to read spark plugs over time? I know how to read spark plugs but over time, would a reading be accurate? Have a Honda whose spark plug is maybe 2 years old, would its reading still be similarly accurate as if it was only after a first good week of use? Stock everything, the porcelain is black, I'm upjetting now with a aftermarket exhaust and filter, should I upjet with if the porcelain is black? With the length of time? Should I try a new reading with a new plug? (Already installed one)
