I have smoke, too. (White) - Honda Forum / Acura Forum

wdb4719 · 06-15-2008, 05:06 PM

Right now I am noticing white smoke from my exhaust when I am at WOT pushing 6,000 and above rpms. Sometimes it's quite alot and sometimes its just a little. My engine is a d series 1.6 liter. I did some searches on google about white smoke. It said the head gasket could need replacing. I have checked the oil. It looks normal. The page I read said to check the coolant level as well. I did. It was at a normal level. The car seems to operate fine. I am just trying to figure out if this smoke is normal. Anybody advice/help is appreciated.

Black smoke is fuel, Bluish gray to white is oil/coolant. If you check your compression that will tell you if it is bad head gasket. If your oil is not mearky with water it is not likely that it will be a head gasket. If you are burning oil, there are a couple of things that can cause that. Hope this helps.

OK, so I bought a compression guage yesterday from the auto parts store. It says I need to disable the ignition system. How would I go about doing this? Also, Would I need disable the fuel system some how? How would I go about doing this as well. Sorry for these nOOb questions.

Thanks for the help,

[Edit] I have been doing some more reading. Would it be possible to just unplug the ECU fuse under the hood? Would this take care of the fuel system and the ignition system with one stone?

No, you still need the ignition to run. What it is telling you is that you don't want spark and fuel. For a compression test you still need the motor to turn over. If you take out the fuel pump fuse that will stop the flow of fuel, that way you don't end up flooding it. If you take off the distributor cap, three screws, that will stop the spark. This way the engine will still turn over.

Here is a good video if you still need help.

Don't pull the cap, I mean you can if you want, but it's easier just to pull the plug on the side of the dizzy with the thick black wire w/ yellow stripe. Thats the power to your coil.
only thing wrong with compression test is it will only narrow down the cylinder, but won't tell you if it's rings gasket or valves.
To me it sounds like valve seals.

Ok, So. I think I got it figured out how to run the test. I just need to know where the fuel pump fuse is. My haynes manual says its somewhere under the drivers side dash. I couldn't find it so I did a google search. I found a yahoo thread that said it was in the underhood relay box. This is where I thought it would have been. But there is no fuse on the diagram that says "Fuel pump". Any pointers as to where and what I am looking for is appreciated! Thanks again for the help!

Should say something like EFI

Shiesh.. I always just disconnect the fuel injector wires.. the four clips easily unplug on top of you intake manifold.
the cylinder your testing has the gauge in it so no spark on the chamber.
who cares if the other chambers spark when there is no fuel in shot into them.
just remember to crank it the same amount for each cylinder to compare pressure properly..
