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.

Am changing plugs on 2006 aveo. Found oil in the

Yeah, kind of. The valve cover gasket needs replaced. The seals around the plugs go first because of heat. If the oil mark was near the top of the plug boot, replace the valve cover gaskets/seal. If it was near the bottom, slap in the plugs and wires.

There is engine oil in the spark plug well of No1 cylinder (the well is about 10-12cm long and the oil is almost up to the top of the spark plug). I'm guessing there is a seal or seals between the cylnder...

Valve cover gasket , this is a common problem and its not the cylinder head it is held in by 6 bolts and is common to leak in to sparkplug area and causes misfire, your spark plugs wires are considered oil soak and you might as well get those replaced,

How do you change the spark plugs and air filter on a 1990 Merc 190e 2.6L? What type of plugs and gap do you recommend? What type of air filter is also recom?

the 2.6 engine is fairly simple, with hood open, check on the left hand side of the engine and you will see a black plastic cover on the top of the motor with six wires coming from it, these are attatched top six plug caps, twist all caps slightly to and fro to break the seal between the rubber of the cap and the plug ceramic, then gently ease each cap off the plugs, you'll then need a plug spanner to remove plugs, reassemble in reverse order. Check your hand book and it will tell you the correct plugs and gaps ( new plugs are normally gapped correctly for the application)

Headlight bulb change

Open the bonnet, look down at the back of the headlight, you will see 3 wires going into a plug which is surrounded by a large rubber seal.
Pull the plug out ( it plugs into the back of the headlight bulb ) . Once the plug is out, remove the rubber seal, it should have a tag to make this easier.
Under the seal there is a bulb holder, the bulb is held in by a springy piece of wire, one end if the wire clip has a small loop, push the loop toward the headlight and then ( with pressure on the loop ) move the clip sideways, ( there is a hook that holds the clip).
The clip will swing out ( one end will pivot ) and the bulb can be removed.
Do not touch the glass part of the bulb as the oils on your fingers can cause the bulb to blow prematurely.
Replace the bulb ,clip and seal ( the seal is marked TOP at the top) and plug the power back in.
Job Done!!
All the best , Marshall

You need a distributor seal. It's about $13. (not to be confused with the cam seal which is on the other side). It's a rubber "O" ring.

Instead of unplugging the plug wires from your distributor cap during removal of the distributor, unplug them from the spark plugs instead so you don't take the chance of scrambling your firing order.

Coolant in # 1 cylnder\clean intake port of intake manifold

Check the lower intake gasket again the new gaskets that are being use made out of plastic with rubber port seals sometimes don't seal right I still used gasket sealer with the new plastic gasket even if it has rubber seals. MY 4.2 v6 had that problem but I went ahead and replaced the head gaskets also just to cover all the bases. And my F-150 has 210,000 miles on it. Make sure you tight the bolts I know it probably calls for something like 8 ft lbs which to me is not tight enough. Double it.
