Does anyone know the spark plug wire order on a d15b7
Oil is leaking into your spark plug holes from the valve chamber. It's not a good idea to leave the oil in the spark plug holes, as it can pool high enough to damage the rubber boots of your spark plug wires, will make the plug hole really messy, and it may eventually become a fire hazard. Below is how to fix it.
Honda's preferred spark plug location means that the plugs (and their wires) must pass through deep recesses in the top of the valve covers to get to the combustion chamber. This gives better plug placement in the combustion chamber, and more zoom for your Honda. It creates a small problem though: Under the valve cover, all around the spark plug recesses, is an open space that is constantly being showered with oil, and that oil will get into the spark plug recesses unless something is done to keep it out. Honda does this by sealing any joins between parts with little rubber donuts (AKA "grommets").
The rubber donuts eventually get old and stop sealing, letting oil seep into the spark plug holes and puddle there. The cure is replacement of all four (or six), along with the valve cover gasket itself (themselves) at the same time. It's an easy project for anyone who's done more than just oil changes.
However, there's a fly in the ointment here: Certain Honda engines, specifically the 4-valve-per-cylinder, single-overhead-cam ones (such as the D15B that's used in many Civics), have an additional rubber seal under the one I just mentioned! This one also gets old and starts leaking, but these are a LOT harder to replace! Not a job for a beginner!
NOTE: The rubber parts under discussion here are not actually red and orange, they're black, I just used colors to make it clearer which was what.
