Last year I picked up a bad D15 Honda engine that I was going to use for tear down experience, so this weekend I pulled out the tools and started to tear it down. By end of Sunday night I had it all apart and pulled the crank and pistons. The experience was great and will help for when I start tearing into my D16Z6 Turbo build engine. There is a sequence of taking things apart and if you figure that out early it makes things easier the next time. I took some pictures of the engine and posted them below. As you can tell the engine was in bad shape with lots of water damage and rust. 1. Here you can see the block with the head pulled off. 2. This cylinder had major rust all over. 3. This image shows the bottom end of the engine including the oil pump pickup. 4. Oil pump is pulled out and is visible on the block. 5. Crankshaft is out and connecting rods are visible as well as bottoms of pistons. 6. Crankshaft out of D15B2 Honda engine. ... Read More

My friend’s car broke down this morning and her engine light came on but being a newer car she needs an ODB2 reader to find out what’s wrong with it. This got me thinking about the possible ODB1 engine error codes that the engine light in a Civic would show if you had a problem. So I made a table below of the possible engine error codes that a 1992-1995 Civic owner could encounter. These codes are easily readable by the number of flashes made by the engine light in diagnostic mode. To get into diagnostic mode you have to short out the diagnostic plug that is under the right side of the glow box. This is a green 2 wire plug that should be in a rubber sleeve. Make sure your ignition is in the OFF position, then pull the plug out of the sleeve and short the two pins with a small wire. Then turn your ignition to the "II" position and count the number of flashes. You might encounter long flashes or short flashes, each long flash means 10 and each short flash means 1. So if you get 2 long flashes and 2 short flashes, your error code is 22 - VTEC Pressure Valve Switch. If you get 3 short flashes ... Read More

Note: This procedure is the same for a 1992-1995 Honda Civic CX, DX, or Si Tools Needed: 8mm Socket Wrench or a Phillips Head Screw Driver   Step One: Open up your hood and make sure you secure the hood post in it's proper place.   Step Two: Use an 8mm Socket Wrench or a Phillips head screw driver to undo all 4 screws holding down the top of the airbox. I would use the 8mm Socket Wrench because it will not strip the head of the screw as easily as a Phillips head screw driver. But if you don't have a 8mm socket wrench then a Phillips head screw driver will do just fine with some do care.     Step Three: Make sure all the screws are totally unscrewed from the bottom part of the airbox. Then grab the top of the airbox and lift it up, if you are having trouble check the screws again but this should lift up with very little effort.    Step Four: Lift out the air filter and replace if needed. Honda recommends to replace every 48,000Km or sooner under severe driving conditions, like driving on dusty roads or near construction sites.   Step Five: Once you put the new air filter in it's place align the top part of the airbox with the bottom half and tighten all the screws. DO NOT ... Read More

Saturday I opened up the hood of the D15 Civic and pressure washed the engine bay, but being careful not to spray water on the distributor. I covered the distributor with a rag and plastic bag to protect it. When I was done spraying it off I got my air compressor out and used compressed air to blow off any water around all electrical plugs and air hoses. I had a friend of mine helping me out so it went really fast and once I was done she asked what those black plugs on top of the valve cover were. I told her they were spark plug wires and that she could pull one out and look at the plug down below. She tried but was scared not to break anything so I pulled one out and then something caught me of guard. When I pulled the plug wire out of the valve cover hole it was full of oil! I said crap how did that get in there. From what I know the only way oil could be in there is from bad plug hole seals. I checked all the plug wires for all cylinders and they ... Read More
